OpenSSL security update for Octopus container?
by Robert Sander 02 Oct '25

02 Oct '25

Hi, I am running a Ceph Octopus cluster in version 15.2.10 setup with the cephadm orchestrator and official Docker hub container images. Yesterday an important security fix was released for libssl and is already packaged for all major distributions. I tried to run "ceph orch upgrade check docker.io/ceph/ceph:v15" but it tells me that the containers do not need to be upgraded. How will this security fix of OpenSSL be deployed in a timely manner to users of the Ceph container images?

Problems with autoscaler (overlapping roots) after changing the pool class
by Massimo Sgaravatto 06 Jan '25

06 Jan '25

Dear all I have just changed the crush rule for all the replicated pools in the following way: ceph osd crush rule create-replicated replicated_hdd default host hdd ceph osd pool set <poolname> crush_rule replicated_hdd See also this [*] thread Before applying this change, these pools were all using the replicated_ruleset rule where the class is not specified. I am noticing now a problem with the autoscaler: "ceph osd pool autoscale-status" doesn't report any output and the mgr log complains about overlapping roots: [pg_autoscaler ERROR root] pool xyz has overlapping roots: {-18, -1} Indeed: # ceph osd crush tree --show-shadow ID CLASS WEIGHT TYPE NAME -18 hdd 1329.26501 root default~hdd -17 hdd 329.14154 rack Rack11-PianoAlto~hdd -15 hdd 54.56085 host ceph-osd-04~hdd 30 hdd 5.45609 osd.30 31 hdd 5.45609 osd.31 ... ... -1 1329.26501 root default -7 329.14154 rack Rack11-PianoAlto -8 54.56085 host ceph-osd-04 30 hdd 5.45609 osd.30 31 hdd 5.45609 osd.31 ... I have already read about this behavior but I have no clear ideas how to fix the problem. I read somewhere that the problem happens when there are rules that force some pools to only use one class and there are also pools which does not make any distinction between device classes All the replicated pools are using the replicated_hdd pool but I also have some EC pools which are using a profile where the class is not specified. As far I understand, I can't force these pools to use only the hdd class: according to the doc I can't change this profile specifying the hdd class (or at least the change wouldn't be applied to the existing EC pools) Any suggestions ? The crush map is available at https://cernbox.cern.ch/s/gIyjbQbmoTFHCrr, if you want to have a look Many thanks, Massimo [*] https://www.mail-archive.com/ceph-users@ceph.io/msg18534.html

Correct Migration Workflow Replicated -> Erasure Code
by Mac Wynkoop 19 Jun '24

19 Jun '24

Hi Everyone, So, I'm in the process of trying to migrate our rgw.buckets.data pool from a replicated rule pool to an erasure coded pool. I've gotten the EC pool set up, good EC profile and crush ruleset, pool created successfully, but when I go to "rados cppool xxx.rgw.buckets.data xxx.rgw.buckets.data.new", I get this error after it transfers 4GB of data: error copying object: (2) No such file or directory error copying pool xxx.rgw.buckets.data => xxx.rgw.buckets.data.new: (2) No such file or directory Is "rados cppool" still the blessed way to do the migration, or has something better/not deprecated been developed that I can use? Thanks, Mac

Re: NoSuchKey on key that is visible in s3 list/radosgw bk
by Eric Ivancich 03 Apr '24

03 Apr '24

I have some questions for those who’ve experienced this issue. 1. It seems like those reporting this issue are seeing it strictly after upgrading to Octopus. From what version did each of these sites upgrade to Octopus? From Nautilus? Mimic? Luminous? 2. Does anyone have any lifecycle rules on a bucket experiencing this issue? If so, please describe. 3. Is anyone making copies of the affected objects (to same or to a different bucket) prior to seeing the issue? And if they are making copies, does the destination bucket have lifecycle rules? And if they are making copies, are those copies ever being removed? 4. Is anyone experiencing this issue willing to run their RGWs with 'debug_ms=1'? That would allow us to see a request from an RGW to either remove a tail object or decrement its reference counter (and when its counter reaches 0 it will be deleted).

Why you might want packages not containers for Ceph deployments
by Matthew Vernon 25 Mar '24

25 Mar '24

Hi, In the discussion after the Ceph Month talks yesterday, there was a bit of chat about cephadm / containers / packages. IIRC, Sage observed that a common reason in the recent user survey for not using cephadm was that it only worked on containerised deployments. I think he then went on to say that he hadn't heard any compelling reasons why not to use containers, and suggested that resistance was essentially a user education question[0]. I'd like to suggest, briefly, that: * containerised deployments are more complex to manage, and this is not simply a matter of familiarity * reducing the complexity of systems makes admins' lives easier * the trade-off of the pros and cons of containers vs packages is not obvious, and will depend on deployment needs * Ceph users will benefit from both approaches being supported into the future We make extensive use of containers at Sanger, particularly for scientific workflows, and also for bundling some web apps (e.g. Grafana). We've also looked at a number of container runtimes (Docker, singularity, charliecloud). They do have advantages - it's easy to distribute a complex userland in a way that will run on (almost) any target distribution; rapid "cloud" deployment; some separation (via namespaces) of network/users/processes. For what I think of as a 'boring' Ceph deploy (i.e. install on a set of dedicated hardware and then run for a long time), I'm not sure any of these benefits are particularly relevant and/or compelling - Ceph upstream produce Ubuntu .debs and Canonical (via their Ubuntu Cloud Archive) provide .debs of a couple of different Ceph releases per Ubuntu LTS - meaning we can easily separate out OS upgrade from Ceph upgrade. And upgrading the Ceph packages _doesn't_ restart the daemons[1], meaning that we maintain control over restart order during an upgrade. And while we might briefly install packages from a PPA or similar to test a bugfix, we roll those (test-)cluster-wide, rather than trying to run a mixed set of versions on a single cluster - and I understand this single-version approach is best practice. Deployment via containers does bring complexity; some examples we've found at Sanger (not all Ceph-related, which we run from packages): * you now have 2 process supervision points - dockerd and systemd * docker updates (via distribution unattended-upgrades) have an unfortunate habit of rudely restarting everything * docker squats on a chunk of RFC 1918 space (and telling it not to can be a bore), which coincides with our internal network... * there is more friction if you need to look inside containers (particularly if you have a lot running on a host and are trying to find out what's going on) * you typically need to be root to build docker containers (unlike packages) * we already have package deployment infrastructure (which we'll need regardless of deployment choice) We also currently use systemd overrides to tweak some of the Ceph units (e.g. to do some network sanity checks before bringing up an OSD), and have some tools to pair OSD / journal / LVM / disk device up; I think these would be more fiddly in a containerised deployment. I'd accept that fixing these might just be a SMOP[2] on our part. Now none of this is show-stopping, and I am most definitely not saying "don't ship containers". But I think there is added complexity to your deployment from going the containers route, and that is not simply a "learn how to use containers" learning curve. I do think it is reasonable for an admin to want to reduce the complexity of what they're dealing with - after all, much of my job is trying to automate or simplify the management of complex systems! I can see from a software maintainer's point of view that just building one container and shipping it everywhere is easier than building packages for a number of different distributions (one of my other hats is a Debian developer, and I have a bunch of machinery for doing this sort of thing). But it would be a bit unfortunate if the general thrust of "let's make Ceph easier to set up and manage" was somewhat derailed with "you must use containers, even if they make your life harder". I'm not going to criticise anyone who decides to use a container-based deployment (and I'm sure there are plenty of setups where it's an obvious win), but if I were advising someone who wanted to set up and use a 'boring' Ceph cluster for the medium term, I'd still advise on using packages. I don't think this makes me a luddite :) Regards, and apologies for the wall of text, Matthew [0] I think that's a fair summary! [1] This hasn't always been true... [2] Simple (sic.)

Re: increasing number of (deep) scrubs
by Frank Schilder 13 Dec '23

13 Dec '23

Hi Dan, thanks for your answer. I don't have a problem with increasing osd_max_scrubs (=1 at the moment) as such. I would simply prefer a somewhat finer grained way of controlling scrubbing than just doubling or tripling it right away. Some more info. These 2 pools are data pools for a large FS. Unfortunately, we have a large percentage of small files, which is a pain for recovery and seemingly also for deep scrubbing. Our OSDs are about 25% used and I had to increase the warning interval already to 2 weeks. With all the warning grace parameters this means that we manage to deep scrub everything about every month. I need to plan for 75% utilisation and a 3 months period is a bit far on the risky side. Our data is to a large percentage cold data. Client reads will not do the check for us, we need to combat bit-rot pro-actively. The reasons I'm interested in parameters initiating more scrubs while also converting more scrubs into deep scrubs are, that 1) scrubs seem to complete very fast. I almost never catch a PG in state "scrubbing", I usually only see "deep scrubbing". 2) I suspect the low deep-scrub count is due to a low number of deep-scrubs scheduled and not due to conflicting per-OSD deep scrub reservations. With the OSD count we have and the distribution over 12 servers I would expect at least a peak of 50% OSDs being active in scrubbing instead of the 25% peak I'm seeing now. It ought to be possible to schedule more PGs for deep scrub than actually are. 3) Every OSD having only 1 deep scrub active seems to have no measurable impact on user IO. If I could just get more PGs scheduled with 1 deep scrub per OSD it would already help a lot. Once this is working, I can eventually increase osd_max_scrubs when the OSDs fill up. For now I would just like that (deep) scrub scheduling looks a bit harder and schedules more eligible PGs per time unit. If we can get deep scrubbing up to an average of 42PGs completing per hour with keeping osd_max_scrubs=1 to maintain current IO impact, we should be able to complete a deep scrub with 75% full OSDs in about 30 days. This is the current tail-time with 25% utilisation. I believe currently a deep scrub of a PG in these pools takes 2-3 hours. Its just a gut feeling from some repair and deep-scrub commands, I would need to check logs for more precise info. Increasing osd_max_scrubs would then be a further and not the only option to push for more deep scrubbing. My expectation would be that values of 2-3 are fine due to the increasingly higher percentage of cold data for which no interference with client IO will happen. Hope that makes sense and there is a way beyond bumping osd_max_scrubs to increase the number of scheduled and executed deep scrubs.

With 8+2, 8+3 pools each scrub is occupying the scrub slot on 10 or 11 OSDs, so at a minimum it could take 3-4x the amount of time to scrub the data than if those were replicated pools. If you want the scrub to complete in time, you need to increase the amount of scrub slots accordingly. On the other hand, IMHO the 1-week deadline for deep scrubs is often much too ambitious for large clusters -- increasing the scrub intervals is one solution, or I find it simpler to increase mon_warn_pg_not_scrubbed_ratio and mon_warn_pg_not_deep_scrubbed_ratio until you find a ratio that works for your cluster. Of course, all of this can impact detection of bit-rot, which anyway can be covered by client reads if most data is accessed periodically. But if the cluster is mostly idle or objects are generally not read, then it would be preferable to increase slots osd_max_scrubs.

It looks like too few scrubs are scheduled for these large OSDs. My estimate is as follows: we have 852 spinning OSDs backing a 8+2 pool with 2024 and an 8+3 pool with 8192 PGs. On average I see something like 10PGs of pool 1 and 12 PGs of pool 2 (deep) scrubbing.

We get the error "wrong peer at address" in dmesg and some jobs on that server seem to get stuck in fs access; log extract below. I found these 2 tracker items https://tracker.ceph.com/issues/23883 and https://tracker.ceph.com/issues/41519, which don't seem to have fixes. My questions: - Is this harmless or does it indicate invalid/corrupted client cache entries? - How to resolve, ignore, umount+mount or reboot? Here an extract from the dmesg log, the error has survived a couple of MDS restarts already: [Mon Mar 6 12:56:46 2023] libceph: mds1 192.168.32.87:6801 wrong peer at address [Mon Mar 6 13:05:18 2023] libceph: wrong peer, want 192.168.32.87:6801/-223958753, got 192.168.32.87:6801/-1572619386 [Mon Mar 6 13:05:18 2023] libceph: mds1 192.168.32.87:6801 wrong peer at address [Mon Mar 6 13:13:50 2023] libceph: wrong peer, want 192.168.32.87:6801/-223958753, got 192.168.32.87:6801/-1572619386 [Mon Mar 6 13:13:50 2023] libceph: mds1 192.168.32.87:6801 wrong peer at address [Mon Mar 6 13:16:41 2023] libceph: mds1 192.168.32.87:6801 socket closed (con state OPEN) [Mon Mar 6 13:16:41 2023] libceph: mds1 192.168.32.87:6801 socket closed (con state OPEN) [Mon Mar 6 13:16:45 2023] ceph: mds1 reconnect start [Mon Mar 6 13:16:45 2023] ceph: mds1 reconnect start [Mon Mar 6 13:16:48 2023] ceph: mds1 reconnect success [Mon Mar 6 13:16:48 2023] ceph: mds1 reconnect success [Mon Mar 6 13:18:13 2023] ceph: update_snap_trace error -22 [Mon Mar 6 13:18:17 2023] libceph: mds7 192.168.32.88:6801 socket closed (con state OPEN) [Mon Mar 6 13:18:17 2023] libceph: mds7 192.168.32.88:6801 socket closed (con state OPEN) [Mon Mar 6 13:18:23 2023] ceph: mds1 recovery completed [Mon Mar 6 13:18:23 2023] ceph: mds1 recovery completed [Mon Mar 6 13:18:28 2023] ceph: mds7 reconnect start [Mon Mar 6 13:18:28 2023] ceph: mds7 reconnect start [Mon Mar 6 13:18:28 2023] ceph: mds7 reconnect success [Mon Mar 6 13:18:29 2023] ceph: mds7 reconnect success [Mon Mar 6 13:18:35 2023] ceph: update_snap_trace error -22 [Mon Mar 6 13:18:35 2023] ceph: mds7 recovery completed [Mon Mar 6 13:18:35 2023] ceph: mds7 recovery completed [Mon Mar 6 13:22:22 2023] libceph: wrong peer, want 192.168.32.87:6801/-223958753, got 192.168.32.87:6801/-453143347 [Mon Mar 6 13:22:22 2023] libceph: mds1 192.168.32.87:6801 wrong peer at address [Mon Mar 6 13:30:54 2023] libceph: wrong peer, want 192.168.32.87:6801/-223958753, got 192.168.32.87:6801/-453143347 [...] [Thu Mar 9 09:37:24 2023] slurm.epilog.cl (31457): drop_caches: 3 [Thu Mar 9 09:38:26 2023] libceph: wrong peer, want 192.168.32.87:6801/-223958753, got 192.168.32.87:6801/-453143347 [Thu Mar 9 09:38:26 2023] libceph: mds1 192.168.32.87:6801 wrong peer at address [Thu Mar 9 09:46:58 2023] libceph: wrong peer, want 192.168.32.87:6801/-223958753, got 192.168.32.87:6801/-453143347 [Thu Mar 9 09:46:58 2023] libceph: mds1 192.168.32.87:6801 wrong peer at address [Thu Mar 9 09:55:30 2023] libceph: wrong peer, want 192.168.32.87:6801/-223958753, got 192.168.32.87:6801/-453143347 [Thu Mar 9 09:55:30 2023] libceph: mds1 192.168.32.87:6801 wrong peer at address [Thu Mar 9 10:04:02 2023] libceph: wrong peer, want 192.168.32.87:6801/-223958753, got 192.168.32.87:6801/-453143347 [Thu Mar 9 10:04:02 2023] libceph: mds1 192.168.32.87:6801 wrong peer at address Thanks and best regards, ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14

rgw multisite sync not syncing data, error: RGW-SYNC:data:init_data_sync_status: ERROR: failed to read remote data log shards
by Christian Rohmann 20 Jul '23

20 Jul '23

Hey ceph-users, I setup a multisite sync between two freshly setup Octopus clusters. In the first cluster I created a bucket with some data just to test the replication of actual data later. I then followed the instructions on https://docs.ceph.com/en/octopus/radosgw/multisite/#migrating-a-single-site… to add a second zone. Things went well and both zones are now happily reaching each other and the API endpoints are talking. Also the metadata is in sync already - both sides are happy and I can see bucket listings and users are "in sync": > # radosgw-admin sync status > realm 13d1b8cb-dc76-4aed-8578-2ce5d3d010e8 (obst) > zonegroup 17a06c15-2665-484e-8c61-cbbb806e11d2 (obst-fra) > zone 6d2c1275-527e-432f-a57a-9614930deb61 (obst-rgn) > metadata sync no sync (zone is master) > data sync source: c07447eb-f93a-4d8f-bf7a-e52fade399f3 (obst-az1) > init > full sync: 128/128 shards > full sync: 0 buckets to sync > incremental sync: 0/128 shards > data is behind on 128 shards > behind shards: [0...127] > and on the other side ... > # radosgw-admin sync status > realm 13d1b8cb-dc76-4aed-8578-2ce5d3d010e8 (obst) > zonegroup 17a06c15-2665-484e-8c61-cbbb806e11d2 (obst-fra) > zone c07447eb-f93a-4d8f-bf7a-e52fade399f3 (obst-az1) > metadata sync syncing > full sync: 0/64 shards > incremental sync: 64/64 shards > metadata is caught up with master > data sync source: 6d2c1275-527e-432f-a57a-9614930deb61 (obst-rgn) > init > full sync: 128/128 shards > full sync: 0 buckets to sync > incremental sync: 0/128 shards > data is behind on 128 shards > behind shards: [0...127] > also the newly created buckets (read: their metadata) is synced.

hi Ernesto and lists, > [1] https://github.com/ceph/ceph/pull/47501 are we planning to backport this to quincy so we can support centos 9 there? enabling that upgrade path on centos 9 was one of the conditions for dropping centos 8 support in reef, which i'm still keen to do if not, can we find another resolution to https://tracker.ceph.com/issues/58832? as i understand it, all of those python packages exist in centos 8. do we know why they were dropped for centos 9? have we looked into making those available in epel?

Small RGW objects and RADOS 64KB minimun size
by Loïc Dachary 31 May '23

31 May '23

Bonjour, Reading Karan's blog post about benchmarking the insertion of billions objects to Ceph via S3 / RGW[0] from last year, it reads: > we decided to lower bluestore_min_alloc_size_hdd to 18KB and re-test. As represented in chart-5, the object creation rate found to be notably reduced after lowering the bluestore_min_alloc_size_hdd parameter from 64KB (default) to 18KB. As such, for objects larger than the bluestore_min_alloc_size_hdd , the default values seems to be optimal, smaller objects further require more investigation if you intended to reduce bluestore_min_alloc_size_hdd parameter. There also is a mail thread dated 2018 on this topic as well, with the same conclusion although using RADOS directly and not RGW[3]. I read the RGW data layout page in the documentation[1] and concluded that by default every object inserted with S3 / RGW will indeed use at least 64kb. A pull request from last year[2] seems to confirm it and also suggests modifying bluestore_min_alloc_size_hdd has adverse side effects. That being said, I'm curious to know if people developed strategies to cope with this overhead. Someone mentioned packing objects together client side to make them larger. But maybe there are simpler ways to do the same?

ln: failed to create hard link 'file name': Read-only file system
by Frank Schilder 26 May '23

26 May '23

Hi all, on an NFS re-export of a ceph-fs (kernel client) I observe a very strange error. I'm un-taring a larger package (1.2G) and after some time I get these errors: ln: failed to create hard link 'file name': Read-only file system The strange thing is that this seems only temporary. When I used "ln src dst" for manual testing, the command failed as above. However, after that I tried "ln -v src dst" and this command created the hard link with exactly the same path arguments. During the period when the error occurs, I can't see any FS in read-only mode, neither on the NFS client nor the NFS server. Funny thing is that file creation and write still works, its only the hard-link creation that fails. For details, the set-up is: file-server: mount ceph-fs at /shares/path, export /shares/path as nfs4 to other server other server: mount /shares/path as NFS More precisely, on the file-server: fstab: MON-IPs:/shares/folder /shares/nfs/folder ceph defaults,noshare,name=NAME,secretfile=sec.file,mds_namespace=FS-NAME,_netdev 0 0 exports: /shares/nfs/folder -no_root_squash,rw,async,mountpoint,no_subtree_check DEST-IP On the host at DEST-IP: fstab: FILE-SERVER-IP:/shares/nfs/folder /mnt/folder nfs defaults,_netdev 0 0 Both, the file server and the client server are virtual machines. The file server is on Centos 8 stream (4.18.0-338.el8.x86_64) and the client machine is on AlmaLinux 8 (4.18.0-425.13.1.el8_7.x86_64). When I change the NFS export from "async" to "sync" everything works. However, that's a rather bad workaround and not a solution. Although this looks like an NFS issue, I'm afraid it is a problem with hard links and ceph-fs. It looks like a race with scheduling and executing operations on the ceph-fs kernel mount. Has anyone seen something like that? Thanks and best regards, ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14

deploying Ceph using FQDN for MON / MDS Services
by Lokendra Rathour 21 Apr '23

21 Apr '23

Hi Team, We have a ceph cluster with 3 storage nodes: 1. storagenode1 - abcd:abcd:abcd::21 2. storagenode2 - abcd:abcd:abcd::22 3. storagenode3 - abcd:abcd:abcd::23 The requirement is to mount ceph using the domain name of MON node: Note: we resolved the domain name via DNS server. For this we are using the command: ``` mount -t ceph [storagenode.storage.com]:6789:/ /backup -o name=admin,secret=AQCM+8hjqzuZEhAAcuQc+onNKReq7MV+ykFirg== ``` We are getting the following logs in /var/log/messages: ``` Jan 24 17:23:17 localhost kernel: libceph: resolve 'storagenode.storage.com' (ret=-3): failed Jan 24 17:23:17 localhost kernel: libceph: parse_ips bad ip ' storagenode.storage.com:6789' ``` We also tried mounting ceph storage using IP of MON which is working fine. Query: Could you please help us out with how we can mount ceph using FQDN.

Cephadm - Error ENOENT: Module not found
by elia.oggian＠cscs.ch 06 Apr '23

06 Apr '23

Hello, After a successful upgrade of a Ceph cluster from 16.2.7 to 16.2.11, I needed to downgrade it back to 16.2.7 as I found an issue with the new version. I expected that running the downgrade with:`ceph orch upgrade start --ceph-version 16.2.7` should have worked fine. However, it blocked right after the downgrade of the first MGR daemon. In fact, the downgraded daemon is not able to use the cephadm module anymore. Any `ceph orch` command fails with the following error: ``` $ ceph orch ps Error ENOENT: Module not found ``` And the downgrade process is therefore blocked. These are the logs of the MGR when issuing the command: ``` Mar 28 12:13:15 astano03 ceph-c57586c4-8e44-11eb-a116-248a07aa8d2e-mgr-astano03-qtzccn[2232770]: debug 2023-03-28T10:13:15.557+0000 7f828fe8c700 0 log_channel(audit) log [DBG] : from='client.3136173 -' entity='client.admin' cmd=[{"prefix": "orch ps", "target": ["mon-mgr", ""]}]: dispatch Mar 28 12:13:15 astano03 ceph-c57586c4-8e44-11eb-a116-248a07aa8d2e-mgr-astano03-qtzccn[2232770]: debug 2023-03-28T10:13:15.558+0000 7f829068d700 0 [orchestrator DEBUG root] _oremote orchestrator -> cephadm.list_daemons(*(None, None), **{'daemon_id': None, 'host': None, 'refresh': False}) Mar 28 12:13:15 astano03 ceph-c57586c4-8e44-11eb-a116-248a07aa8d2e-mgr-astano03-qtzccn[2232770]: debug 2023-03-28T10:13:15.558+0000 7f829068d700 -1 no module 'cephadm' Mar 28 12:13:15 astano03 ceph-c57586c4-8e44-11eb-a116-248a07aa8d2e-mgr-astano03-qtzccn[2232770]: debug 2023-03-28T10:13:15.558+0000 7f829068d700 0 [orchestrator DEBUG root] _oremote orchestrator -> cephadm.get_feature_set(*(), **{}) Mar 28 12:13:15 astano03 ceph-c57586c4-8e44-11eb-a116-248a07aa8d2e-mgr-astano03-qtzccn[2232770]: debug 2023-03-28T10:13:15.558+0000 7f829068d700 -1 no module 'cephadm' Mar 28 12:13:15 astano03 ceph-c57586c4-8e44-11eb-a116-248a07aa8d2e-mgr-astano03-qtzccn[2232770]: debug 2023-03-28T10:13:15.558+0000 7f829068d700 -1 mgr.server reply reply (2) No such file or directory Module not found ``` Other interesting MGR logs are: ``` 2023-03-28T11:05:59.519+0000 7fcd16314700 4 mgr get_store get_store key: mgr/cephadm/upgrade_state 2023-03-28T11:05:59.519+0000 7fcd16314700 -1 mgr load Failed to construct class in 'cephadm' 2023-03-28T11:05:59.519+0000 7fcd16314700 -1 mgr load Traceback (most recent call last): e "/usr/share/ceph/mgr/cephadm/module.py", line 450, in __init__ elf.upgrade = CephadmUpgrade(self) e "/usr/share/ceph/mgr/cephadm/upgrade.py", line 111, in __init__ elf.upgrade_state: Optional[UpgradeState] = UpgradeState.from_json(json.loads(t)) e "/usr/share/ceph/mgr/cephadm/upgrade.py", line 92, in from_json eturn cls(**c) rror: __init__() got an unexpected keyword argument 'daemon_types' 2023-03-28T11:05:59.521+0000 7fcd16314700 -1 mgr operator() Failed to run module in active mode ('cephadm') ``` Which seem to relate to the new feature of staggered upgrades. Please note that before, everything was working fine with version 16.2.7. I am currently stuck in this situation with only one MGR daemon on version 16.2.11 which is the only one still working fine: ``` [root@astano01 ~]# ceph orch ps | grep mgr mgr.astano02.mzmewn astano02 *:8443,9283 running (5d) 43s ago 2y 455M - 16.2.11 7a63bce27215 e2d7806acf16 mgr.astano03.qtzccn astano03 *:8443,9283 running (3m) 22s ago 95m 383M - 16.2.7 463ec4b1fdc0 cc0d88864fa1 ``` Does anyone already faced this issue or knows how can I make the 16.2.7 MGR load the cephadm module correctly? Thanks in advance for any help!

Misplaced objects greater than 100%
by Johan Hattne 06 Apr '23

06 Apr '23

Dear all; Up until a few hours ago, I had a seemingly normally-behaving cluster (Quincy, 17.2.5) with 36 OSDs, evenly distributed across 3 of its 6 nodes. The cluster is only used for CephFS and the only non-standard configuration I can think of is that I had 2 active MDSs, but only 1 standby. I had also doubled mds_cache_memory limit to 8 GB (all OSD hosts have 256 G of RAM) at some point in the past. Then I rebooted one of the OSD nodes. The rebooted node held one of the active MDSs. Now the node is back up: ceph -s says the cluster is healthy, but all PGs are in a active+clean+remapped state and 166.67% of the objects are misplaced (dashboard: -66.66% healthy). The data pool is a threefold replica with 5.4M object, the number of misplaced objects is reported as 27087410/16252446. The denominator in the ratio makes sense to me (16.2M / 3 = 5.4M), but the numerator does not. I also note that the ratio is *exactly* 5 / 3. The filesystem is still mounted and appears to be usable, but df reports it as 100% full; I suspect it would say 167% but that is capped somewhere. Any ideas about what is going on? Any suggestions for recovery? // Best wishes; Johan

CephFS thrashing through the page cache
by Ashu Pachauri 05 Apr '23

05 Apr '23

We have an internal use case where we back the storage of a proprietary database by a shared file system. We noticed something very odd when testing some workload with a local block device backed file system vs cephfs. We noticed that the amount of network IO done by cephfs is almost double compared to the IO done in case of a local file system backed by an attached block device. We also noticed that CephFS thrashes through the page cache very quickly compared to the amount of data being read and think that the two issues might be related. So, I wrote a simple test. 1. I wrote 10k files 400KB each using dd (approx 4 GB data). 2. I dropped the page cache completely. 3. I then read these files serially, again using dd. The page cache usage shot up to 39 GB for reading such a small amount of data. Following is the code used to repro this in bash: for i in $(seq 1 10000); do dd if=/dev/zero of=test_${i} bs=4k count=100 done sync; echo 1 > /proc/sys/vm/drop_caches for i in $(seq 1 10000); do dd if=test_${i} of=/dev/null bs=4k count=100 done The ceph version being used is: ceph version 15.2.13 (c44bc49e7a57a87d84dfff2a077a2058aa2172e2) octopus (stable) The ceph configs being overriden: WHO MASK LEVEL OPTION VALUE RO mon advanced auth_allow_insecure_global_id_reclaim false mgr advanced mgr/balancer/mode upmap mgr advanced mgr/dashboard/server_addr 127.0.0.1 * mgr advanced mgr/dashboard/server_port 8443 * mgr advanced mgr/dashboard/ssl false * mgr advanced mgr/prometheus/server_addr 0.0.0.0 * mgr advanced mgr/prometheus/server_port 9283 * osd advanced bluestore_compression_algorithm lz4 osd advanced bluestore_compression_mode aggressive osd advanced bluestore_throttle_bytes 536870912 osd advanced osd_max_backfills 3 osd advanced osd_op_num_threads_per_shard_ssd 8 * osd advanced osd_scrub_auto_repair true mds advanced client_oc false mds advanced client_readahead_max_bytes 4096 mds advanced client_readahead_max_periods 1 mds advanced client_readahead_min 0 mds basic mds_cache_memory_limit 21474836480 client advanced client_oc false client advanced client_readahead_max_bytes 4096 client advanced client_readahead_max_periods 1 client advanced client_readahead_min 0 client advanced fuse_disable_pagecache false The cephfs mount options (note that readahead was disabled for this test): /mnt/cephfs type ceph (rw,relatime,name=cephfs,secret=<hidden>,acl,rasize=0) Any help or pointers are appreciated; this is a major performance issue for us.

RGW can't create bucket
by Kamil Madac 05 Apr '23

05 Apr '23

Hi, One of my customers had a correctly working RGW cluster with two zones in one zonegroup and since a few days ago users are not able to create buckets and are always getting Access denied. Working with existing buckets works (like listing/putting objects into existing bucket). The only operation which is not working is bucket creation. We also tried to create a new user, but the behavior is the same, and he is not able to create the bucket. We tried s3cmd, python script with boto library and also Dashboard as admin user. We are always getting Access Denied. Zones are in-sync. Has anyone experienced such behavior? Thanks in advance, here are some outputs: $ s3cmd -c .s3cfg_python_client mb s3://test ERROR: Access to bucket 'test' was denied ERROR: S3 error: 403 (AccessDenied) Zones are in-sync: Primary cluster: # radosgw-admin sync status realm 5429b434-6d43-4a18-8f19-a5720a89c621 (solargis-prod) zonegroup 00e4b3ff-1da8-4a86-9f52-4300c6d0f149 (solargis-prod-ba) zone 6067eec6-a930-45c7-af7d-a7ef2785a2d7 (solargis-prod-ba-dc) metadata sync no sync (zone is master) data sync source: e84fd242-dbae-466c-b4d9-545990590995 (solargis-prod-ba-hq) syncing full sync: 0/128 shards incremental sync: 128/128 shards data is caught up with source Secondary cluster: # radosgw-admin sync status realm 5429b434-6d43-4a18-8f19-a5720a89c621 (solargis-prod) zonegroup 00e4b3ff-1da8-4a86-9f52-4300c6d0f149 (solargis-prod-ba) zone e84fd242-dbae-466c-b4d9-545990590995 (solargis-prod-ba-hq) metadata sync syncing full sync: 0/64 shards incremental sync: 64/64 shards metadata is caught up with master data sync source: 6067eec6-a930-45c7-af7d-a7ef2785a2d7 (solargis-prod-ba-dc) syncing full sync: 0/128 shards incremental sync: 128/128 shards data is caught up with source -- Kamil Madac

How mClock profile calculation works, and IOPS
by Luis Domingues 03 Apr '23

03 Apr '23

Hi, I am reading reading some documentation about mClock and have two questions. First, about the IOPS. Are those IOPS disk IOPS or other kind of IOPS? And what the assumption of those? (Like block size, sequential or random reads/writes)? And the second question, How mClock calculates its profiles? I have my lab cluster running Quincy, and I have this parameters for mClock: "osd_mclock_max_capacity_iops_hdd": "450.000000", "osd_mclock_profile": "balanced", According to the documentation: https://docs.ceph.com/en/quincy/rados/configuration/mclock-config-ref/#bala… I am expecting to have: "osd_mclock_scheduler_background_best_effort_lim": "999999", "osd_mclock_scheduler_background_best_effort_res": "90", "osd_mclock_scheduler_background_best_effort_wgt": "2", "osd_mclock_scheduler_background_recovery_lim": "675", "osd_mclock_scheduler_background_recovery_res": "180", "osd_mclock_scheduler_background_recovery_wgt": "1", "osd_mclock_scheduler_client_lim": "450", "osd_mclock_scheduler_client_res": "180", "osd_mclock_scheduler_client_wgt": "1", But what I get is: "osd_mclock_scheduler_background_best_effort_lim": "999999", "osd_mclock_scheduler_background_best_effort_res": "18", "osd_mclock_scheduler_background_best_effort_wgt": "2", "osd_mclock_scheduler_background_recovery_lim": "135", "osd_mclock_scheduler_background_recovery_res": "36", "osd_mclock_scheduler_background_recovery_wgt": "1", "osd_mclock_scheduler_client_lim": "90", "osd_mclock_scheduler_client_res": "36", "osd_mclock_scheduler_client_wgt": "1", Which seems very low according to what my disk seems to be able to handle. Is this calculation the expected one? Or did I miss something on how those profiles are populated? Luis Domingues Proton AG

Eccessive occupation of small OSDs
by Nicola Mori 03 Apr '23

03 Apr '23

Dear Ceph users, my cluster is made up of 10 old machines, with uneven number of disks and disk size. Essentially I have just one big data pool (6+2 erasure code, with host failure domain) for which I am currently experiencing a very poor available space (88 TB of which 40 TB occupied, as reported by df -h on hosts mounting the cephfs) compared to the raw one (196.5 TB). I have a total of 104 OSDs and 512 PGs for the pool; I cannot increment the PG number since the machines are old and with very low amount of RAM, and some of them are already overloaded. In this situation I'm seeing a high occupation of small OSDs (500 MB) with respect to bigger ones (2 and 4 TB) even if the weight is set equal to disk capacity (see below for ceph osd tree). For example OSD 9 is at 62% occupancy even with weight 0.5 and reweight 0.75, while the highest occupancy for 2 TB OSDs is 41% (OSD 18) and 4 TB OSDs is 23% (OSD 79). I guess this high occupancy for 500 MB OSDs combined with erasure code size and host failure domain might be the cause of the poor available space, could this be true? The upmap balancer is currently running but I don't know if and how much it could improve the situation. Any hint is greatly appreciated, thanks.

monitoring apply_latency / commit_latency ?
by Matthias Ferdinand 02 Apr '23

02 Apr '23

Hi, I would like to understand how the per-OSD data from "ceph osd perf" (i.e. apply_latency, commit_latency) is generated. So far I couldn't find documentation on this. "ceph osd perf" output is nice for a quick glimpse, but is not very well suited for graphing. Output values are from the most recent 5s-averages apparently. With "ceph daemon osd.X perf dump" OTOH, you get quite a lot of latency metrics, while it is just not obvious to me how they aggregate into apply_latency and commit_latency. Or some comparably easy read latency metric (something that is missing completely in "ceph osd perf"). Can somebody shed some light on this? Regards Matthias

avg apply latency went up after update from octopus to pacific
by Boris Behrens 02 Apr '23

02 Apr '23

Hi, today I did the first update from octopus to pacific, and it looks like the avg apply latency went up from 1ms to 2ms. All 36 OSDs are 4TB SSDs and nothing else changed. Someone knows if this is an issue, or am I just missing a config value? Cheers Boris

Failing to create monitor in a working cluster.
by pmestre＠gmail.com 01 Apr '23

01 Apr '23

Hello, i've been running a 3 node proxmox cluster with 4 ceph osd for 3 years as a production cluster. As a test for trying to move ceph cluster network, i destroyed one of the 3 working monitors and tried to recreate it. After destroying it, the new monitor refuses to join the cluster, even in the old network. I've tried all steps in documentation "Troubleshooting monitors" section.

Ceph Failure and OSD Node Stuck Incident
by petersun＠raksmart.com 31 Mar '23

31 Mar '23

We encountered a Ceph failure where the system became unresponsive with no IOPS or throughput after encountering a failed node. Upon investigation, it appears that the OSD process on one of the Ceph storage nodes is stuck, but ping is still responsive. However, during the failure, Ceph was unable to recognize the problematic node, which resulted in all other OSDs in the cluster experiencing slow operations and no IOPS in the cluster at all. Here's the timeline of the incident: - At 10:40, an alert is triggered, indicating a problem with the OSD. - After the alert, Ceph becomes unresponsive with no IOPS or throughput. - At 11:26, an engineer discovers that there is a gradual OSD failure, with 6 out of 12 OSDs on the node being down. - At 11:46, the Ceph engineer is unable to SSH into the faulty node and attempts a soft restart, but the "smartmontools" process is stuck while shutting down the server. Ping works during this time. - After waiting for about one or two minutes, a hard restart is attempted for the server. - At 11:57, after the Ceph node starts normally, service resumes as usual, indicating that the issue has been resolved. Here is some basic information about our services: - `Mon: 5 daemons, quorum host001, host002, host003, host004, host005 (age 4w)` - `Mgr: host005 (active, since 4w), standbys: host001, host002, host003, host004` - `Osd: 218 osds: 218 up (since 22h), 218 in (since 22h)` We have a cluster with 19 nodes, including 15 SSD nodes and 4 HDD nodes. In total, there are 218 OSDs. The SSD nodes have 11 OSDs with Samsung EVO 870 SSD and each drive DB/WAL by 1.6T NVME drive. We are using Ceph version 15.2.17 (8a82819d84cf884bd39c17e3236e0632ac146dc4) octopus (stable). Here is the health check detail: [root@node21 ~]# ceph health detail HEALTH_WARN 1 osds down; Reduced data availability: 12 pgs inactive, 12 pgs peering; Degraded data redundancy: 272273/43967625 objects degraded (0.619%), 88 pgs degraded, 5 pgs undersized; 18192 slow ops, oldest one blocked for 3730 sec, daemons [osd.0,osd.1,osd.101,osd.103,osd.107,osd.108,osd.109,osd.11,osd.111,osd.112]... have slow ops.

I have the following questions: 1. Why couldn't Ceph detect the faulty node and automatically abandon its resources? Can anyone provide more troubleshooting guidance for this case? 2. What is Ceph's detection mechanism and where can I find related information? All of our production cloud machines were affected and suspended. If RBD is unstable, we cannot continue to use Ceph technology for our RBD source. 3. Did we miss any patches or bug fixes? 4. Is there anyone who can suggest improvements and how we can quickly detect and avoid similar issues in the future?

./install-deps.sh takes several hours
by Arvid Picciani 31 Mar '23

31 Mar '23

Hi again, something is very wrong with my hardware it seems and i'm slowly turning insane. I'm trying to debug why ceph has incredibly poor performance for us. we've got - 3 EPYC 7713 dual-cpu systems - datacenter nvme drives (3GB/s top) - 100G infiniband ceph does 800MB/s read max, CPU is idle, network is idle, I/O nowhere near saturation now while hunting for queues, i wanted to recompile ceph and poke around abit, but ./install-deps.sh is now running for 6 hours with the exact same problem. CPU is idle, network is idle, zero I/O what am i doing wrong? is there another computer resource we're bottlenecked on that i just dont know about? -- +4916093821054

hi, how to understand ``Improvements in releases beginning with Nautilus 14.2.12 and Octopus 15.2.6 enable better utilization of arbitrary DB device sizes, and the Pacific release brings experimental dynamic level support. `` in the document ``https://docs.ceph.com/en/quincy/rados/configuration/bluestore-config-ref/#sizing`` is there a related patch??

Upgrade from 16.2.7. to 16.2.11 failing on OSDs
by Lo Re Giuseppe 31 Mar '23

31 Mar '23

Dear all, On one of our clusters I started the upgrade process from 16.2.7 to 16.2.11. Mon and mgr and crash processes were done easily/quickly, then at the first attempt of upgrading a OSD container the upgrade process stopped because of the OSD process is not able to start after the upgrade. Does anyone have any hint on how to unblock the upgrade? Some details below: Regards, Giuseppe I started the upgrade process with the cephadm command: “”” [root@naret-monitor01 ~]# ceph orch upgrade start --ceph-version 16.2.11 Initiating upgrade to quay.io/ceph/ceph:v16.2.11 “”” After a short time: “”” [root@naret-monitor01 ~]# ceph orch upgrade status { "target_image": quay.io/ceph/ceph@sha256:1b9803c8984bef8b82f05e233e8fe8ed8f0bba8e5cc2c57f6efaccbeea682add<mailto:quay.io/ceph/ceph@sha256:1b9803c8984bef8b82f05e233e8fe8ed8f0bba8e5cc2c57f6efaccbeea682add>, "in_progress": true, "which": "Upgrading all daemon types on all hosts", "services_complete": [ "crash", "mon", "mgr" ], "progress": "64/2039 daemons upgraded", "message": "Error: UPGRADE_REDEPLOY_DAEMON: Upgrading daemon osd.4 on host naret-osd01 failed.", "is_paused": true } “”” The ceph health command reports: “”” [root@naret-monitor01 ~]# ceph health detail HEALTH_WARN 1 failed cephadm daemon(s); 1 osds down; Degraded data redundancy: 2654362/6721382840 objects degraded (0.039%), 14 pgs degraded, 14 pgs undersized; Upgrading daemon osd.4 on host naret-osd01 failed.

how ceph OSD bench works?
by Luis Domingues 31 Mar '23

31 Mar '23

Hi, I am currently testing some new disks, doing some benchmarks and stuff, and I would like to undertand how the OSD bench works. If I quicky explain our setup, we have a small ceph cluster, where our new disks are inserted. And we have some pools with no replication at all, and 1 PG only, up-mapped to those new disks. So I can do some benchmarks on them. The thing that is odd, is that doing some tests with fio tool, I have similar results on all disks, and doing the rados bench during 5 minutes as well. But the OSD bench at startup of the OSD, for mClock to configure osd_mclock_max_capacity_iops_hdd gives me a very big difference between disks. (600 vs 2200). I am running Pacific on this test cluster. Is there anywhere documentation of how this works? Or if anyone could explain that would be great. I did not found any documentation on how OSD benchmark works, only how to used it. But playing a little bit with it, it seems the results we get is highly dependent on the block sizes we use. Same for rados bench, results are dependent, at least on my tests, of the block size we use, which I found a little bit weird to be honest. And as mClock depends on that, it is impactful performance wise. On our cluster we can reach a lot better performances if we teak those values, instead of letting the cluster do proper measurements. And this looks to impact certain disk vendors more than others. Luis Domingues Proton AG

Call for Submissions IO500 ISC23
by IO500 Committee 30 Mar '23

30 Mar '23

Stabilization Period: Monday, April 3rd - Friday, April 14th, 2023 Submission Deadline: Tuesday, May 16st, 2023 AoE The IO500 is now accepting and encouraging submissions for the upcoming 12th semi-annual IO500 list, in conjunction with ISC23. Once again, we are also accepting submissions to the 10 Client Node Challenge to encourage the submission of small scale results. The new ranked lists will be announced at the ISC23 BoF [1]. We hope to see many new results. What's New 1. Creation of Production and Research Lists - Starting with ISC'22, we proposed a separation of the list into separate Production and Research lists. This better reflects the important distinction between storage systems that run in production environments and those that may use more experimental hardware and software configurations. At ISC23, we will formally create these two lists and users will be able to submit to either of the two lists (and their 10 client-node counterparts). Please see the requirements for each list on the IO500 rules page [3]. 2. New Submission Tool - There is now a new IO500 submission tool that improves the overall submission experience. Users can create accounts and then update and manage all of their submissions through that account. As part of this new tool, we have improved the submission fields that describe the hardware and software of the system under test. For reproducibility and analysis reasons, we now made the easily obtainable fields mandatory - data from storage servers are for users often difficult to obtain, therefore, most remain optional. As a new system, there may be quirks, please reach out on Slack or the mailing list if you see any issues. Further details will be released on the submission page [2]. 3. Reproducibility - Every submission will now receive a reproducibility score based upon the provided system details and the reproducibility questionnaire. This score will inform the community on the amount of details provided in the submission and the obtainability of the storage system. Further, this score will be used to evaluate if a submission is eligible for the Production list. 4. New Phases - We are continuing to evaluate the inclusion of optional test phases for additional key workloads - split easy/hard find phases, 4KB and 1MB random read/write phases, and concurrent metadata operations. This is called an extended run. At the moment, we collect the information to verify that additional phases do not significantly impact the results of a standard run and an extended run to facilitate comparisons between the existing and new benchmark phases. In a future release, we may include some or all of these results as part of the standard benchmark. The extended results are not currently included in the scoring of any ranked list. Background The benchmark suite is designed to be easy to run and the community has multiple active support channels to help with any questions. Please note that submissions of all sizes are welcome; the site has customizable sorting, so it is possible to submit on a small system and still get a very good per-client score, for example. Additionally, the list is about much more than just the raw rank; all submissions help the community by collecting and publishing a wider corpus of data. More details below. Following the success of the Top500 in collecting and analyzing historical trends in supercomputer technology and evolution, the IO500 was created in 2017, published its first list at SC17, and has grown continually since then. The need for such an initiative has long been known within High-Performance Computing; however, defining appropriate benchmarks has long been challenging. Despite this challenge, the community, after long and spirited discussion, finally reached consensus on a suite of benchmarks and a metric for resolving the scores into a single ranking. The multi-fold goals of the benchmark suite are as follows: 1. Maximizing simplicity in running the benchmark suite 2. Encouraging optimization and documentation of tuning parameters for performance 3. Allowing submitters to highlight their "hero run" performance numbers 4. Forcing submitters to simultaneously report performance for challenging IO patterns. Specifically, the benchmark suite includes a hero-run of both IOR and mdtest configured however possible to maximize performance and establish an upper-bound for performance. It also includes an IOR and mdtest run with highly prescribed parameters in an attempt to determine a lower performance bound. Finally, it includes a namespace search as this has been determined to be a highly sought-after feature in HPC storage systems that has historically not been well-measured. Submitters are encouraged to share their tuning insights for publication. The goals of the community are also multi-fold: 1. Gather historical data for the sake of analysis and to aid predictions of storage futures 2. Collect tuning information to share valuable performance optimizations across the community 3. Encourage vendors and designers to optimize for workloads beyond "hero runs" 4. Establish bounded expectations for users, procurers, and administrators The IO500 follows a two-staged approach. First, there will be a two-week stabilization period during which we encourage the community to verify that the benchmark runs properly on a variety of storage systems. During this period the benchmark may be updated based upon feedback from the community. The final benchmark will then be released. We expect that runs compliant with the rules made during the stabilization period will be valid as a final submission unless a significant defect is found. 10 Client Node I/O Challenge The 10 Client Node Challenge is conducted using the regular IO500 benchmark, however, with the rule that exactly 10 client nodes must be used to run the benchmark. You may use any shared storage with any number of servers. We will announce the results in the Production and Research lists as well as in separate derived lists. Birds-of-a-Feather Once again, we encourage you to submit [2] to join our community, and to attend the ISC23 BoF [1], where we will announce the new IO500 Production and Research lists and their 10 client node counterparts. The current list includes results from twenty different storage system types and 70 institutions. We hope that the upcoming list grows even more.

I have a cluster that I increased the the number of PGs on because the autoscaler wasn't working as expected. It's recovering the misplaced objects, but a OSD just failed, and refuses to come back up. The device is readable to the OS, and there are 2 other OSDs on the same node that are online. I looked online, but haven't found anything relevant.

Controlling the number of open files from ceph client
by bhattacharya.soumya.ou＠gmail.com 30 Mar '23

30 Mar '23

Hi Ceph Users, My goal is to control the number of files a ceph client can open to the backend ceph filesystem at once to control the metadata transaction load. In this experiment, I have a ceph client on version Quincy on a physical server. The fstab entry below shows the options with which the ceph filesystem is mounted on it. In particular, I used caps_max=1900 option with the intention to limit the total number of open files by this client at once to 1900 at the mount point /ourdisk/hpc_scratch. # cat /etc/fstab ... 10.251.0.30:6789,10.251.0.31:6789,10.251.0.32:6789,10.251.0.33:6789,10.251.0.40:6789:/volumes/hpc_scratch/scratch/525205e7-4f71-4383-89ce-53e2ec68d017 /ourdisk/hpc_scratch ceph fsc,caps_max=1900,name=oscer,secretfile=/etc/ceph/client.oscer.secret 0 0 To test if this worked, I used fio command to create 4000 files at once in a directory on Ceph at /ourdisk/hpc_scratch/soumya/fio_tests/client_c003. During the run, I looked at the caps file (copied below), and it shows the number of used caps is 4007. Given my limited knowledge, it seems to me that the client was able to open 4000 files at once. # head /sys/kernel/debug/ceph/d5d5b0aa-1867-11eb-9f4a-bc97e1724ff1.client483151133/caps total 5032 avail 1025 used 4007 reserved 0 min 1024 ino mds issued implemented -------------------------------------------------- 0x200136e01b6 0 pAsLsXsFs pAsLsXsFs 0x1 0 pAsLsXsFs pAsLsXsFs Is there any way I can control how many simultaneous files a ceph client can open (preferably from the client side, if not then from the ceph side but on an individual client)? If so, how can I check the number of files a client is opening at a given time? Thank you for your time, Soumya PS: I understand that the number of capabilities is not the number of open files, but that's the closest mount option I could find for this experiment.

17.2.6 RC available
by Yuri Weinstein 30 Mar '23

30 Mar '23

We are publishing a release candidate this time for users to try for testing only. Please note this RC had only limited testing. Full testing is being done now. Upgrading has been tested on some internal clusters, and the final upgrade of the longest-running cluster there is in progress. The branch name: https://github.com/ceph/ceph/tree/quincy-release https://shaman.ceph.com/builds/ceph/quincy-release/23eb3b2f0fc65087846571af… To install dev packages see https://docs.ceph.com/en/quincy/install/get-packages/#ceph-development-pack… The container build see - https://quay.ceph.io/ceph-ci/ceph:quincy-release Release notes: https://github.com/ceph/ceph/pull/50721 ***Don’t use this RC on production clusters!*** The goal is to give users time to test and give feedback on RC releases while our upstream long-running cluster also runs the same RC release during that time (period of one week). Please respond to this email to provide any feedback on issues found in this release. Thx YuriW

OSD down cause all OSD slow ops
by petersun＠raksmart.com 30 Mar '23

30 Mar '23

We experienced a Ceph failure causing the system to become unresponsive with no IOPS or throughput due to a problematic OSD process on one node. This resulted in slow operations and no IOPS for all other OSDs in the cluster. The incident timeline is as follows: Alert triggered for OSD problem. 6 out of 12 OSDs on the node were down. Soft restart attempted, but smartmontools process stuck while shutting down server. Hard restart attempted and service resumed as usual. Our Ceph cluster has 19 nodes, 218 OSDs, and is using version 15.2.17 octopus (stable). Questions: 1. What is Ceph's detection mechanism? Why couldn't Ceph detect the faulty node and automatically abandon its resources? 2. Did we miss any patches or bug fixes? 3. Suggestions for improvements to quickly detect and avoid similar issues in the future?

Re: Upgrade from 16.2.7. to 16.2.11 failing on OSDs
by Lo Re Giuseppe 30 Mar '23

30 Mar '23

To add, on this, the issue seemed related to a process (ceph-volume) which was doing check operations on all devices. The systemctl osd service was timing out because of that and the osd daemon was going into error state. We noticed that version 17.2.5 had a change related to ceph-volume, in particular https://tracker.ceph.com/issues/57627. We decided to skip 16.2.11 and jump to 17.2.5. This second attempt went well, so the issue is now solved. Note: the upgrade 16.2.7 -> 16.2.11 went smoothly in a TDS cluster with identical OS/software, but much smaller, 3 nodes with a couple of disk each, so the issue seems really to be about the number of devices and nodes. Regards, Giuseppe On 30.03.23, 16:56, "Lo Re Giuseppe" <giuseppe.lore(a)cscs.ch <mailto:giuseppe.lore@cscs.ch>> wrote: Dear all, On one of our clusters I started the upgrade process from 16.2.7 to 16.2.11.

I think that the backported fix for this issue made it into ceph v16.2.11. https://ceph.io/en/news/blog/2023/v16-2-11-pacific-released/ "ceph-volume: Pacific backports (pr#47413, Guillaume Abrioux, Zack Cerza, Arthur Outhenin-Chalandre)" https://github.com/ceph/ceph/pull/47413/commits/4252cc44211f0ccebf388374744… -Patrick

ceph osd new: possible inconsistency whether UUID is a mandatory argument
by Oliver Schmidt 29 Mar '23

29 Mar '23

Hi everyone, I discovered a documentation inconsistency in Ceph Nautilus and would like to know whether this is still the case in the latest ceph release before reporting a bug. Unfortunately, I only have access to a Nautilus cluster right now. The quincy docs state [1]: > Create the OSD. If no UUID is given, it will be set automatically when the OSD starts up. The following command will output the OSD number, which you will need for subsequent steps: > >ceph osd create [{uuid} [{id}]] But the man pages [2] state that `ceph osd create` is deprecated in favour of `ceph osd new {<uuid>} {<id>} -i {<params.json>}`, with both uuid and id still being marked as optional parameters. But when actually running `ceph osd new` without a specified UUID, I get ``` Invalid command: missing required parameter uuid(<uuid>) osd new <uuid> {<osdname (id|osd.id)>} : Create a new OSD. If supplied, the `id` to be replaced needs to exist and have been previously destroyed. Reads secrets from JSON file via `-i <file>` (see man page). Error EINVAL: invalid command ``` under Nautilus. Is this still the case under Quincy, can someone reproduce this for me?

5 host setup with NVMe's and HDDs
by Tino Todino 29 Mar '23

29 Mar '23

Hi folks. Just looking for some up to date advice please from the collective on how best to set up CEPH on 5 Proxmox hosts each configured with the following: AMD Ryzen 7 5800X CPU 64GB RAM 2x SSD (as ZFS boot disk for Proxmox) 1x 500GB NVMe for DB/WAL 1x 1TB NVMe as an OSD 1x 16TB SATA HDD as an OSD 2x 10GB NIC (One for Public and one for Cluster networks) 1 GB NIC for management interface The CEPH solution will be used primarily for storage of another Proxmox cluster's virtual machines and their data. We'd like a fast pool using the NVMe's for critical VMs and a slower HDD based pool for VM's that don't require such fast disk access and perhaps require more storage capacity. To expand in the future we will probably add more hosts in the same sort of configuration and/or replace NVMe/HDDs OSDs with more capacious ones. Ideas for configuration welcome please.

orphan multipart objects in Ceph cluster
by Ramin Najjarbashi 29 Mar '23

29 Mar '23

I hope this email finds you well. I wanted to share a recent experience I had with our Ceph cluster and get your feedback on a solution I came up with. Recently, we had some orphan objects stuck in our cluster that were not visible by any client like s3cmd, boto3, and mc. This caused some confusion for our users, as the sum of all objects in their buckets was much less than what we showed in the panel. We made some adjustments for them, but the issue persisted. As we have billions of objects in our cluster, using normal tools to find orphans was impossible. So, I came up with a tricky way to handle the situation. I created a bash script that identifies and removes the orphan objects using radosgw-admin and rados commands. Here is the script: https://gist.github.com/RaminNietzsche/b9baa06b69fc5f56d907f3c953769182 I am hoping to get some feedback from the community on this solution. Have any of you faced similar challenges with orphan objects in your Ceph clusters? Do you have any suggestions or improvements for my script? Thank you for your time and help.

osd_mclock_max_capacity_iops_ssd && multiple osd by nvme ?
by DERUMIER, Alexandre 29 Mar '23

29 Mar '23

Hi, I would like to advise to correctly tune osd_mclock_max_capacity_iops_ssd when you have multiple osd by nvme ? Does it need simply to divide the total iops of the nvme by number of osd ? But maybe it'll impact performance if more read/write are done on one of the osd ? I really don't known if we still need multiple osd by nvme in quincy ? Maybe it could be easier with a simple osd ? Regards, Alexandre

RGW can't create bucket
by kamil.madac＠gmail.com 29 Mar '23

29 Mar '23

Hi, One of my customers had a correctly working RGW cluster with two zones in one zonegroup and since a few days ago users are not able to create buckets and are always getting Access denied. Working with existing buckets works (like listing/putting objects into existing bucket). The only operation which is not working is bucket creation. We also tried to create a new user, but the behavior is the same, and he is not able to create the bucket. We tried s3cmd, python script with boto library and also Dashboard as admin user. We are always getting Access Denied. Zones are in-sync. Has anyone experienced such behavior? Thanks in advance, here are some outputs: $ s3cmd -c .s3cfg_python_client mb s3://test ERROR: Access to bucket 'test' was denied ERROR: S3 error: 403 (AccessDenied) Zones are in-sync: Primary cluster: # radosgw-admin sync status realm 5429b434-6d43-4a18-8f19-a5720a89c621 (solargis-prod) zonegroup 00e4b3ff-1da8-4a86-9f52-4300c6d0f149 (solargis-prod-ba) zone 6067eec6-a930-45c7-af7d-a7ef2785a2d7 (solargis-prod-ba-dc) metadata sync no sync (zone is master) data sync source: e84fd242-dbae-466c-b4d9-545990590995 (solargis-prod-ba-hq) syncing full sync: 0/128 shards incremental sync: 128/128 shards data is caught up with source Secondary cluster: # radosgw-admin sync status realm 5429b434-6d43-4a18-8f19-a5720a89c621 (solargis-prod) zonegroup 00e4b3ff-1da8-4a86-9f52-4300c6d0f149 (solargis-prod-ba) zone e84fd242-dbae-466c-b4d9-545990590995 (solargis-prod-ba-hq) metadata sync syncing full sync: 0/64 shards incremental sync: 64/64 shards metadata is caught up with master data sync source: 6067eec6-a930-45c7-af7d-a7ef2785a2d7 (solargis-prod-ba-dc) syncing full sync: 0/128 shards incremental sync: 128/128 shards data is caught up with source

s3-select introduction blog / Trino integration
by Gal Salomon 28 Mar '23

28 Mar '23

Hi https://ceph.io/en/news/blog/2022/s3select-intro/ Recently I published a blog on s3-select. the Blog discusses what it is, and why it is required. the last paragraph discusses the Trino(analytic SQL utility) and its integration with Ceph/s3select. that integration is still on-work, and it is quite promising. Trino does not just provides a comprehensive SQL but also provides scalable processing for the SQL statements. we will be glad to hear your ideas and comments. Gal.

Unexpected slow read for HDD cluster (good write speed)
by Rafael Weingartner 28 Mar '23

28 Mar '23

Hello guys! I would like to ask if somebody has already experienced a similar situation. We have a new cluster with 5 nodes with the following setup: - 128 GB of RAM - 2 cpus Intel(R) Intel Xeon Silver 4210R - 1 NVME of 2 TB for the rocks DB caching - 5 HDDs of 14TB - 1 NIC dual port of 25GiB in BOND mode. We are starting with a single dual port NIC (the bond has 50GiB in total), the design has been prepared so a new NIC can be added, and a new BOND can be created, where we intend to offload the cluster network. Therefore, logically speaking, we already configured different VLANs and networks for public and cluster traffic of Ceph. We are using Ubuntu 20.04 with Ceph Octopus. It is a standard deployment that we are used to. During our initial validations and evaluations of the cluster, we are reaching write speeds between 250-300MB/s, which would be the ballpark for this kind of setup for HDDs with the NVME as Rocks.db cache (in our experience). However, the issue is the reading process. While reading, we barely hit the mark of 100MB/s; we would expect at least something similar to the write speed. These tests are being performed in a pool with a replication factor of 3. We have already checked the disks, and they all seem to be reading just fine. The network does not seem to be the bottleneck either (checked with atop while reading/writing to the cluster). Have you guys ever encountered similar situations? Do you have any tips for us to proceed with the troubleshooting? We suspect that we are missing some small tuning detail, which is affecting the read performance only, but so far we could not pinpoint it. Any help would be much appreciated :)

Question about adding SSDs
by Kyriazis, George 27 Mar '23

27 Mar '23

Hello ceph community, We have a ceph cluster (Proxmox based) with is HDD-based. We’ve had some performance and “slow MDS” issues while doing VM/CT backups from the Proxmox cluster, especially when rebalancing is going on at the same time. My thought is that one of following is going to improve performance / response: 1. Add an M.2 drive for DB store on each node 2. Migrate the cephfs metadata pool to SSDs We have ~25 nodes with ~3 OSDs per node. (1) is a lot of work and will cost more. (2) seems more risky (to me) since the metadata pool would have to be migrated (potential loss in transit?) Which one of the 2 solutions above will give us more bang for the buck, or just plain better performance? I would hate to implement (1) to find out that another solution would’ve been better. Any other solutions that I haven’t thought of? Thank you! George

rbd cp vs. rbd clone + rbd flatten
by Tony Liu 27 Mar '23

Hi, I want 1) copy a snapshot to an image, 2) no need to copy snapshots, 3) no dependency after copy, 4) all same image format 2. In that case, is rbd cp the same as rbd clone + rbd flatten? I ran some tests, seems like it, but want to confirm, in case of missing anything. Also, seems cp is a bit faster and flatten, is that true? Thanks! Tony

Hi, Has anybody noticed this? ceph orch ps shows version, container and image id as unknown only for mon, mgr and osds. Ceph health is OK and all daemons are running fine. cephadm ls shows values for version, container and image id. root@cr21meg16ba0101:~# cephadm shell ceph orch ps Inferring fsid a6f52598-e5cd-4a08-8422-7b6fdb1d5dbe Using recent ceph image ceph/daemon@sha256:261bbe628f4b438f5bf10de5a8ee05282f2697a5a2cb7ff7668f776b61b9d586 NAME HOST PORTS STATUS REFRESHED AGE MEM USE MEM LIM VERSION IMAGE ID CONTAINER ID crash.cr21meg16ba0101 cr21meg16ba0101 running (4d) 2m ago 5w 7107k -

ceph orch ps shows unknown in version, container and image id columns
by anantha.adiga＠intel.com 27 Mar '23

27 Mar '23

Hi Has anybody noticed this issue? For all mgr, mon and osd daemons orch ps shows version, container and image ids as unknown. Ceph health is ok and all daemons are running fine. cephadm ls shows correct details of version, container and image ids . What could be the issue? and how to resolve it? ceph version 16.2.5 (0883bdea7337b95e4b611c768c0279868462204a) pacific (stable) cephadm shell ceph -s Inferring fsid a6f52598-e5cd-4a08-8422-7b6fdb1d5dbe Using recent ceph image ceph/daemon@sha256:261bbe628f4b438f5bf10de5a8ee05282f2697a5a2cb7ff7668f776b61b9d586 cluster: id: a6f52598-e5cd-4a08-8422-7b6fdb1d5dbe health: HEALTH_OK services: mon: 3 daemons, quorum cr21meg16ba0101,cr21meg16ba0102,cr21meg16ba0103 (age 4d) mgr: cr21meg16ba0101(active, since 42h), standbys: cr21meg16ba0103, cr21meg16ba0102 mds: 1/1 daemons up, 2 standby osd: 72 osds: 72 up (since 4d), 72 in (since 5w) rgw: 3 daemons active (3 hosts, 1 zones) data: volumes: 1/1 healthy pools: 16 pools, 577 pgs objects: 3.86M objects, 12 TiB usage: 18 TiB used, 108 TiB / 126 TiB avail pgs: 577 active+clean io: client: 255 B/s rd, 115 KiB/s wr, 0 op/s rd, 3 op/s wr mds.cephfs.cr21meg16ba0103.yacxeu cr21meg16ba0103 running (5w) 2m ago 5w 38.2M - 16.2.5 6e73176320aa 79599f7ca3c8 mgr.cr21meg16ba0101 cr21meg16ba0101 running 2m ago 5w - - <unknown> <unknown> <unknown> mgr.cr21meg16ba0102 cr21meg16ba0102 running 2m ago 5w - - <unknown> <unknown> <unknown> mgr.cr21meg16ba0103 cr21meg16ba0103 running 2m ago 5w - - <unknown> <unknown> <unknown> mon.cr21meg16ba0101 cr21meg16ba0101 running 2m ago 5w - 2048M <unknown> <unknown> <unknown> mon.cr21meg16ba0102 cr21meg16ba0102 running 2m ago 5w - 2048M <unknown> <unknown> <unknown> mon.cr21meg16ba0103 cr21meg16ba0103 running 2m ago 5w - 2048M <unknown> <unknown> <unknown> nfs.nfs-1.0.63.cr21meg16ba0102.kkxpfh cr21meg16ba0102 *:12049 running (5w) 2m ago 5w 132M - 3.5 6e73176320aa fd617b99d70a nfs.nfs-1.1.0.cr21meg16ba0101.qhdmrq cr21meg16ba0101 *:12049 running (4d) 2m ago 5w 117M - 3.5 6e73176320aa 15e21064041d nfs.nfs-1.2.0.cr21meg16ba0103.wvmquo cr21meg16ba0103 *:12049 running (5w) 2m ago 5w 136M - 3.5 6e73176320aa edb9df63489d node-exporter.cr21meg16ba0101 cr21meg16ba0101 *:9100 running (4d) 2m ago 5w 79.3M - 0.17.0 b3e7f67a1480 e94d14814946 node-exporter.cr21meg16ba0102 cr21meg16ba0102 *:9100 running (5w) 2m ago 5w 102M - 0.17.0 b3e7f67a1480 86165fa7b916 node-exporter.cr21meg16ba0103 cr21meg16ba0103 *:9100 running (5w) 2m ago 5w 88.1M - 0.17.0 b3e7f67a1480 898008baaa66 osd.0 cr21meg16ba0101 running 2m ago 5w - 22.0G <unknown> <unknown> <unknown> osd.1 cr21meg16ba0103 running 2m ago 5w - 22.0G <unknown> <unknown> <unknown>

Ceph cluster out of balance after adding OSDs
by Pat Vaughan 27 Mar '23

27 Mar '23

We setup a small Ceph cluster about 6 months ago with just 6x 200GB OSDs with one EC 4x2 pool. When we created that pool, we enabled pg_autoscale. The OSDs stayed pretty well balanced. After our developers released a new "feature" that caused the storage to balloon up to over 80%, we added another 6x 200GB OSDs. When we did that, we looked at the number of PGs for that pool, and found that there was only 1 for the rgw.data and rgw.log pools, and "osd pool autoscale-status" doesn't return anything, so it looks like that hasn't been working. The rebalance operation was extremely slow, and wasn't balancing out osd.0, so we bumped up the PGs for the rgw.data pool to 16. All the OSDs except osd.0 balanced out quickly, but that one OSDs utilization keeps climbing, and the number of misplaced objects is increasing, rather than decreasing. We set noscrub and nodeep-scrub so scrubbing wouldn't slow down the process. At this point, I don't want to do any more tuning to this cluster until we can get it back to a healthy state, but it's not fixing itself. I'm open to any ideas. Here's the output of ceph -s: cluster: id: 159d23e4-2a36-11ed-8b6e-fd27d573fa65 health: HEALTH_WARN 1 pools have many more objects per pg than average noscrub,nodeep-scrub flag(s) set 1 backfillfull osd(s) Low space hindering backfill (add storage if this doesn't resolve itself): 12 pgs backfill_toofull 7 pool(s) backfillfull services: mon: 3 daemons, quorum ceph3,ceph5,ceph6 (age 6h) mgr: ceph5.ksxevx(active, since 23h), standbys: ceph4.frkyyl, ceph6.slvpzl osd: 12 osds: 12 up (since 11h), 12 in (since 11h); 12 remapped pgs flags noscrub,nodeep-scrub rgw: 3 daemons active (3 hosts, 1 zones) data: pools: 7 pools, 161 pgs objects: 28.61M objects, 211 GiB usage: 1.5 TiB used, 834 GiB / 2.3 TiB avail pgs: 91779228/171665865 objects misplaced (53.464%) 149 active+clean 12 active+remapped+backfill_toofull io: client: 11 KiB/s rd, 61 KiB/s wr, 11 op/s rd, 27 op/s wr progress: Global Recovery Event (23h) [=========================...] (remaining: 115m) ceph df: --- RAW STORAGE --- CLASS SIZE AVAIL USED RAW USED %RAW USED ssd 2.3 TiB 834 GiB 1.5 TiB 1.5 TiB 65.24 TOTAL 2.3 TiB 834 GiB 1.5 TiB 1.5 TiB 65.24 --- POOLS --- POOL ID PGS STORED OBJECTS USED %USED MAX AVAIL .mgr 1 1 897 KiB 2 2.6 MiB 0.18 479 MiB .rgw.root 2 32 7.1 KiB 18 204 KiB 0.01 479 MiB charlotte.rgw.log 3 32 27 KiB 347 2.0 MiB 0.14 479 MiB charlotte.rgw.control 4 32 0 B 9 0 B 0 479 MiB charlotte.rgw.meta 5 32 9.7 KiB 16 167 KiB 0.01 479 MiB charlotte.rgw.buckets.data 6 16 734 GiB 28.61M 1.1 TiB 99.87 958 MiB charlotte.rgw.buckets.index 7 16 16 GiB 691 47 GiB 97.12 479 MiB ceph osd tree: ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF -1 2.34357 root default -3 0.39059 host ceph1 0 ssd 0.19530 osd.0 up 0.89999 1.00000 1 ssd 0.19530 osd.1 up 1.00000 1.00000 -5 0.39059 host ceph2 6 ssd 0.19530 osd.6 up 1.00000 1.00000 7 ssd 0.19530 osd.7 up 1.00000 1.00000 -7 0.39059 host ceph3 2 ssd 0.19530 osd.2 up 1.00000 1.00000 8 ssd 0.19530 osd.8 up 1.00000 1.00000 -9 0.39059 host ceph4 3 ssd 0.19530 osd.3 up 1.00000 1.00000 9 ssd 0.19530 osd.9 up 1.00000 1.00000 -11 0.39059 host ceph5 4 ssd 0.19530 osd.4 up 1.00000 1.00000 10 ssd 0.19530 osd.10 up 1.00000 1.00000 -13 0.39059 host ceph6 5 ssd 0.19530 osd.5 up 1.00000 1.00000 11 ssd 0.19530 osd.11 up 1.00000 1.00000 ceph osd df: ID CLASS WEIGHT REWEIGHT SIZE RAW USE DATA OMAP META AVAIL %USE VAR PGS STATUS 0 ssd 0.19530 0.89999 200 GiB 190 GiB 130 GiB 12 GiB 48 GiB 10 GiB 94.94 1.46 52 up 1 ssd 0.19530 1.00000 200 GiB 7.3 GiB 9.8 MiB 6.4 GiB 858 MiB 193 GiB 3.64 0.06 42 up 6 ssd 0.19530 1.00000 200 GiB 148 GiB 97 GiB 14 GiB 38 GiB 52 GiB 74.06 1.14 51 up 7 ssd 0.19530 1.00000 200 GiB 133 GiB 97 GiB 2 KiB 35 GiB 67 GiB 66.47 1.02 43 up 2 ssd 0.19530 1.00000 200 GiB 134 GiB 97 GiB 12 KiB 37 GiB 66 GiB 66.94 1.03 40 up 8 ssd 0.19530 1.00000 200 GiB 136 GiB 97 GiB 2.2 GiB 36 GiB 64 GiB 67.85 1.04 40 up 3 ssd 0.19530 1.00000 200 GiB 134 GiB 97 GiB 4 KiB 37 GiB 66 GiB 66.95 1.03 41 up 9 ssd 0.19530 1.00000 200 GiB 138 GiB 97 GiB 5.2 GiB 36 GiB 62 GiB 69.19 1.06 49 up 4 ssd 0.19530 1.00000 200 GiB 137 GiB 97 GiB 4.3 GiB 36 GiB 63 GiB 68.62 1.05 42 up 10 ssd 0.19530 1.00000 200 GiB 139 GiB 97 GiB 5.5 GiB 36 GiB 61 GiB 69.31 1.06 48 up 5 ssd 0.19530 1.00000 200 GiB 134 GiB 97 GiB 7 KiB 38 GiB 66 GiB 67.13 1.03 34 up 11 ssd 0.19530 1.00000 200 GiB 136 GiB 97 GiB 2.2 GiB 36 GiB 64 GiB 67.80 1.04 49 up TOTAL 2.3 TiB 1.5 TiB 1.1 TiB 52 GiB 414 GiB 834 GiB 65.24 MIN/MAX VAR: 0.06/1.46 STDDEV: 19.95 Thanks in advance if anyone has any suggestions.

EC profiles where m>k (EC 8+12)
by Fabien Sirjean 27 Mar '23

27 Mar '23

Hi Ceph users! I've been proposed an interesting EC setup I hadn't thought about before. Scenario is : we have two server rooms and want to store ~4PiB with the ability to loose 1 server room without loss of data or RW availability. For the context, performance is not needed (cold storage mostly, used as a big filesystem). The idea is to use EC 8+12 over 24 servers (12 on each server room), so if we loose 1 room we still have half of the EC parts (10/20) and are able to loose 2 more servers before reaching the point where we loose data. I find this pretty elegant when working on a two-sites context, as efficiency is 40% (better than 33% three times replication) and the redundancy is good. What do you think of this setup ? Did you ever used EC profiles with M > K ? Thanks for sharing your thoughts! Cheers, Fabien

Workload performance varying between 2 executions
by Nguetchouang Ngongang Kevin 27 Mar '23

27 Mar '23

Good morning. I just setup a ceph environment, 9 storage nodes and i mount it on a cephfs on a 10th independent node. I execute a fio workload once i got a 3Mb/s throughput. When i reexecute the same workload after a certain time i got this time a 9Mb/s throughput. Do you know why this is happening ?

cephadm cluster move /var/lib/docker to separate device fails
by Karsten Nielsen 25 Mar '23

25 Mar '23

Hi, I have setup a ceph cluster with cephadm with docker backend. I want to move /var/lib/docker to a separate device to get better performance and less load on the OS device. I tried that by stopping docker copy the content of /var/lib/docker to the new device and mount the new device to /var/lib/docker. The other containers started as expected and continues to work and run as expected. But the ceph containers seems to be broken. I am not able to get them back in working state. I have tried to remove the host with `ceph orch host rm itcnchn-bb4067` and readd it but no effect. The strange thing is that 2 of 4 containers comes up as expected. ceph orch ps itcnchn-bb4067 NAME HOST STATUS REFRESHED AGE VERSION IMAGE NAME IMAGE ID CONTAINER ID crash.itcnchn-bb4067 itcnchn-bb4067 running (18h) 10m ago 4w 15.2.7 docker.io/ceph/ceph:v15 2bc420ddb175 2af28c4571cf mds.cephfs.itcnchn-bb4067.qzoshl itcnchn-bb4067 error 10m ago 4w <unknown> docker.io/ceph/ceph:v15 <unknown> <unknown> mon.itcnchn-bb4067 itcnchn-bb4067 error 10m ago 18h <unknown> docker.io/ceph/ceph:v15 <unknown> <unknown> rgw.ikea.dc9-1.itcnchn-bb4067.gtqedc itcnchn-bb4067 running (18h) 10m ago 4w 15.2.7 docker.io/ceph/ceph:v15 2bc420ddb175 00d000aec32b Docker logs from the active manager does not say much about what is wrong debug 2021-01-05T09:57:52.537+0000 7fdb69691700 0 log_channel(cephadm) log [INF] : Reconfiguring mds.cephfs.itcnchn-bb4067.qzoshl (unknown last config time)... debug 2021-01-05T09:57:52.541+0000 7fdb69691700 0 log_channel(cephadm) log [INF] : Reconfiguring daemon mds.cephfs.itcnchn-bb4067.qzoshl on itcnchn-bb4067 debug 2021-01-05T09:57:52.973+0000 7fdb64e88700 0 log_channel(cluster) log [DBG] : pgmap v347: 241 pgs: 241 active+clean; 18 GiB data, 50 GiB used, 52 TiB / 52 TiB avail; 18 KiB/s rd, 78 KiB/s wr, 24 op/s debug 2021-01-05T09:57:53.085+0000 7fdb69691700 0 log_channel(cephadm) log [INF] : Reconfiguring mon.itcnchn-bb4067 (unknown last config time)... debug 2021-01-05T09:57:53.085+0000 7fdb69691700 0 log_channel(cephadm) log [INF] : Reconfiguring daemon mon.itcnchn-bb4067 on itcnchn-bb4067 debug 2021-01-05T09:57:53.625+0000 7fdb69691700 0 log_channel(cephadm) log [INF] : Reconfiguring rgw.ikea.dc9-1.itcnchn-bb4067.gtqedc (unknown last config time)... debug 2021-01-05T09:57:53.629+0000 7fdb69691700 0 log_channel(cephadm) log [INF] : Reconfiguring daemon rgw.ikea.dc9-1.itcnchn-bb4067.gtqedc on itcnchn-bb4067 debug 2021-01-05T09:57:54.141+0000 7fdb69691700 0 log_channel(cephadm) log [INF] : Reconfiguring crash.itcnchn-bb4067 (unknown last config time)... debug 2021-01-05T09:57:54.141+0000 7fdb69691700 0 log_channel(cephadm) log [INF] : Reconfiguring daemon crash.itcnchn-bb4067 on itcnchn-bb4067 - Karsten

Unbalanced OSDs when pg_autoscale enabled
by 郑亮 24 Mar '23

24 Mar '23

Hi all, I have a 9 node cluster running *Pacific 16.2.10*. OSDs live on 9 of the nodes with each one having 4 x 1.8T ssd and 8 x 10.9T hdd for a total of 108 OSDs. We create three crush roots as belows. 1. The hdds (8x9=72) of all nodes form a large crush root, which is used as a data pool, and object storage and cephfs share this crush root. 2. Take 3 ssds from the 4 ssds of each node as rbd block storage. 3. An ssd on each remaining node is used as an index pool for cephfs and object storage.

Generated signurl is accessible from restricted IPs in bucket policy
by Aggelos Toumasis 24 Mar '23

24 Mar '23

Hi there, We noticed after creating a signurl that the bucket resources were accessible from IPs that were originally restricted from accessing them (using a bucket policy). Using the s3cmd utility we confirmed that the Policy is correctly applied and you can access it only for the allowed IPs. Is this an expected behavior or do we miss something? Thanks!

With Ceph Quincy, the "ceph" package does not include ceph-volume anymore
by Geert Kloosterman 24 Mar '23

24 Mar '23

Hi all, Until Ceph Pacific, installing just the "ceph" package was enough to get everything needed to deploy Ceph. However, with Quincy, ceph-volume was split off into its own package, and it is not automatically installed anymore. Here we can see it is not listed as a dependency: $ rpm -q --requires ceph binutils ceph-mds = 2:17.2.5-0.el8 ceph-mgr = 2:17.2.5-0.el8 ceph-mon = 2:17.2.5-0.el8 ceph-osd = 2:17.2.5-0.el8 rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(FileDigests) <= 4.6.0-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rpmlib(PayloadIsXz) <= 5.2-1 systemd Should I file a bug for this? Best regards, Geert Kloosterman

RGW can't create bucket
by Kamil Madac 24 Mar '23

24 Mar '23

Hi, One of my customers had a correctly working RGW cluster with two zones in one zonegroup and since a few days ago users are not able to create buckets and are always getting Access denied. Working with existing buckets works (like listing/putting objects into existing bucket). The only operation which is not working is bucket creation. We also tried to create a new user, but the behavior is the same, and he is not able to create the bucket. We tried s3cmd, python script with boto library and also Dashboard as admin user. We are always getting Access Denied. Zones are in-sync. Has anyone experienced such behavior? Thanks in advance, here are some outputs: $ s3cmd -c .s3cfg_python_client mb s3://test ERROR: Access to bucket 'test' was denied ERROR: S3 error: 403 (AccessDenied) Zones are in-sync: Primary cluster: # radosgw-admin sync status realm 5429b434-6d43-4a18-8f19-a5720a89c621 (solargis-prod) zonegroup 00e4b3ff-1da8-4a86-9f52-4300c6d0f149 (solargis-prod-ba) zone 6067eec6-a930-45c7-af7d-a7ef2785a2d7 (solargis-prod-ba-dc) metadata sync no sync (zone is master) data sync source: e84fd242-dbae-466c-b4d9-545990590995 (solargis-prod-ba-hq) syncing full sync: 0/128 shards incremental sync: 128/128 shards data is caught up with source Secondary cluster: # radosgw-admin sync status realm 5429b434-6d43-4a18-8f19-a5720a89c621 (solargis-prod) zonegroup 00e4b3ff-1da8-4a86-9f52-4300c6d0f149 (solargis-prod-ba) zone e84fd242-dbae-466c-b4d9-545990590995 (solargis-prod-ba-hq) metadata sync syncing full sync: 0/64 shards incremental sync: 64/64 shards metadata is caught up with master data sync source: 6067eec6-a930-45c7-af7d-a7ef2785a2d7 (solargis-prod-ba-dc) syncing full sync: 0/128 shards incremental sync: 128/128 shards data is caught up with source -- Kamil Madac <https://kmadac.github.io/>

Unexpected ceph pool creation error with Ceph Quincy
by Geert Kloosterman 23 Mar '23

23 Mar '23

Hi all, I'm trying out Ceph Quincy (17.2.5) for the first time and I'm running into unexpected behavior of "ceph osd pool create". When not passing any pg_num and pgp_num values, I get the following error with Quincy: [root@gjk-ceph ~]# ceph osd pool create asdf Error ERANGE: 'pgp_num' must be greater than 0 and lower or equal than 'pg_num', which in this case is 1 I checked with Ceph Pacific (16.2.11) and there the extra arguments are not needed. I expected it would use osd_pool_default_pg_num and osd_pool_default_pgp_num as defined in my ceph.conf: [root@gjk-ceph ~]# ceph-conf -D | grep 'osd_pool_default_pg' osd_pool_default_pg_autoscale_mode = on osd_pool_default_pg_num = 8 osd_pool_default_pgp_num = 8 At least, this is what appears to be used with Pacific. Is this an intended change of behavior? I could not find anything related in the release notes. Best regards, Geert Kloosterman

Ceph performance problems
by Dominik Baack 23 Mar '23

23 Mar '23

Hi, we are currently testing out ways to increase Ceph performance because what we experience so far is very close to unusable. For the test cluster we utilizing 4 nodes with the following hardware data: Dual 200GBe Mellanox Ethernet 2x EPYC Rome 7302 16x 32GB 3200MHz ECC 9x 15.36TB Micron 9300 Pro For production this will be extended to all 8 nodes if it shows promising results. - Ceph was installed with cephadm. - MDS and ODS are located on the same nodes. - Mostly using stock config - Network performance tested with iperf3 seems fine, 26Gbits/s with -P4 on single port (details below). Close to 200Gbits with 10 parallel instances and servers. When testing a mounted CephFS on the working nodes in various configurations I only got <50MB/s for fuse mount and <270MB/s for kernel mounts. (dd command and output attached below) In addition ceph dashboard and our graphana monitoring reports packet loss on all relevant interfaces during load. Which does not occur during the normal iperf load tests or rsync/scp file transfer. Rados Bench shows performance around 2000MB/s which is not max performance of the SSDs but fine for us (details below). Why is the filesystem so slow compared to the individual components?

MDS host in OSD blacklist
by Frank Schilder 23 Mar '23

23 Mar '23

Hi all, we have an octopus v15.2.17 cluster and observe that one of our MDS hosts showed up in the OSD blacklist: # ceph osd blacklist ls 192.168.32.87:6801/3841823949 2023-03-22T10:08:02.589698+0100 192.168.32.87:6800/3841823949 2023-03-22T10:08:02.589698+0100 I see an MDS restart that might be related; see log snippets below. There are no clients running on this host, only OSDs and one MDS. What could be the reason for the blacklist entries? Thanks!

Moving From BlueJeans to Jitsi for Ceph meetings
by Mike Perez 22 Mar '23

22 Mar '23

Hi everyone, We have been using BlueJeans to meet and record some of our meetings that later get posted to our YouTube channel. Unfortunately, we have to figure out a new meeting platform due to Red Hat discontinuing BlueJeans by the end of this month. Google Meets is an option, but some users in other countries have trouble using Google's services. For some meetings, we have tried out Jitsi, and it works well, meets our requirements, and is free. Does anyone else have suggestions for another free meeting platform that provides recording capabilities? -- Mike Perez

Re: Ceph Bluestore tweaks for Bcache
by Matthias Ferdinand 21 Mar '23

21 Mar '23

ceph version: 17.2.0 on Ubuntu 22.04 non-containerized ceph from Ubuntu repos cluster started on luminous I have been using bcache on filestore on rotating disks for many years without problems. Now converting OSDs to bluestore, there are some strange effects. If I create the bcache device, set its rotational flag to '1', then do ceph-volume lvm create ... --crush-device-class=hdd the OSD comes up with the right parameters and much improved latency compared to OSD directly on /dev/sdX. ceph osd metatdata ... shows "bluestore_bdev_type": "hdd", "rotational": "1" But after reboot, bcache rotational flag is set '0' again, and the OSD now comes up with "rotational": "0" Latency immediately starts to increase (and continually increases over the next days, possibly due to accumulating fragmention). These wrong settings stay in place even if I stop the OSD, set the bcache rotational flag to '1' again and restart the OSD. I have found no way to get back to the original settings other than destroying and recreating the OSD. I guess I am just not seeing something obvious, like from where these settings get pulled at OSD startup. I even created udev rules to set bcache rotational=1 at boot time, before any ceph daemon starts, but it did not help. Something running after these rules reset the bcache rotationl flags back to 0. Haven't found the culprit yet, but not sure if it even matters. Are these OSD settings (bluestore_bdev_type, rotational) persisted somewhere and can they be edited and pinned? Alternatively, can I manually set and persist the relevant bluestore tunables (per OSD / per device class) so as to make the bcache rotational flag irrelevant after the OSD is first created?

Changing os to ubuntu from centos 8
by Szabo, Istvan (Agoda) 21 Mar '23

21 Mar '23

Hi, I'd like to change the os to ubuntu 20.04.5 from my bare metal deployed octopus 15.2.14 on centos 8. On the first run I would go with octopus 15.2.17 just to not make big changes in the cluster. I've found couple of threads on the mailing list but those were containerized (like: Re: Upgrade/migrate host operating system for ceph nodes (CentOS/Rocky) or Re: Migrating CEPH OS looking for suggestions). Wonder what is the proper steps for this kind of migration? Do we need to start with mgr or mon or rgw or osd? Is it possible to reuse the osd with ceph-volume scan on the reinstalled machine? I'd stay with baremetal deployment and even maybe with octopus but I'm curious your advice.

Very slow backfilling/remapping of EC pool PGs
by Gauvain Pocentek 21 Mar '23

21 Mar '23

Hello all, We have an EC (4+2) pool for RGW data, with HDDs + SSDs for WAL/DB. This pool has 9 servers with each 12 disks of 16TBs. About 10 days ago we lost a server and we've removed its OSDs from the cluster. Ceph has started to remap and backfill as expected, but the process has been getting slower and slower. Today the recovery rate is around 12 MiB/s and 10 objects/s. All the remaining unclean PGs are backfilling: data: volumes: 1/1 healthy pools: 14 pools, 14497 pgs objects: 192.38M objects, 380 TiB usage: 764 TiB used, 1.3 PiB / 2.1 PiB avail pgs: 771559/1065561630 objects degraded (0.072%) 1215899/1065561630 objects misplaced (0.114%) 14428 active+clean 50 active+undersized+degraded+remapped+backfilling 18 active+remapped+backfilling 1 active+clean+scrubbing+deep We've checked the health of the remaining servers, and everything looks like (CPU/RAM/network/disks). Any hints on what could be happening? Thank you, Gauvain

Upgrade 16.2.10 --> 16.2.11 OSD "UPGRADE_REDEPLOY_DAEMON" failed
by Marco Pizzolo 20 Mar '23

20 Mar '23

Hello Everyone, We made the mistake of trying to patch to 16.2.11 from 16.2.10 which has been stable as we felt that 16.2.11 had been out for a while already. As luck would have it, we are having failure after failure with OSDs not upgrading successfully, and have 355 more OSDs to go. I'm pretty sure we're not alone on this and am wondering what others have done to address. Appreciate all suggestions. Thanks, Marco

Multiple instance_id and services for rbd-mirror daemon
by Aielli, Elia 20 Mar '23

20 Mar '23

Hi, I'm facing a strange issue and google doesn't seem to help me. I've a couple of clusters with Octopus v15.2.17, recently upgraded from 15.2.13 I had a rbd mirror service correctly working between the two clusters, i then updated, and after some days where all was ok, I've come to the situation where I have a single DAEMON, but multiple services (on different version tho), each one with its own instance_id, giving you some insight: rbd mirror pool status mypool --verbose health: WARNING daemon health: OK image health: WARNING images: 37 total 2 starting_replay 35 replaying DAEMONS service 123673101: instance_id: 127483700 client_id: admin hostname: DR-Host1 version: *15.2.13* leader: false health: OK service 123674106: instance_id: 127208040 client_id: admin hostname: DR-Host1 version: *15.2.13* leader: false health: OK service 123675375: instance_id: 124630539 client_id: admin hostname: DR-Host1 version: *15.2.13* leader: true health: OK service 124670331: instance_id: 127208013 client_id: backup hostname: DR-Host1 version: *15.2.17* leader: false health: OK As you can see one has the "leader" section as true, and the other are false, I'd like to delete the first 2 false ones, then delete the true one with 15.2.13 and hope the last one becomes true. Do any of you faced any similar issue or can help me in killing the wrong services? Let me know, thanks in advance! Elia

RBD latency
by Murilo Morais 17 Mar '23

17 Mar '23

Good evening everyone! Guys, what to expect latency for RBD images in a cluster with only HDD (36 HDDs)? Sometimes I see that the write latency is around 2-5 ms in some images even with very low IOPS and bandwidth while the read latency is around 0.2-0.7 ms. For a cluster with only HDD is this latency expected? Is there any parameter I can study to improve? What do you recommend for tuning in the OS? The latency between machines is always around 0.1ms, all connected via fiber optics. Thanks in advance!

Concerns about swap in ceph nodes
by sbryan Song 16 Mar '23

16 Mar '23

Hello, We have a 6-node ceph cluster, all of them have osd running and 3 of them (ceph-1 to ceph-3 )also has the ceph-mgr and ceph-mon. Here is the detailed configuration of each node (swap on ceph-1 to ceph-3 has been disabled after the alarm): # ceph-1 free -h total used free shared buff/cache available Mem: 187Gi 38Gi 5.4Gi 4.1Gi 143Gi 142Gi Swap: 0B 0B 0B # ceph-2 free -h total used free shared buff/cache available Mem: 187Gi 49Gi 2.6Gi 4.0Gi 135Gi 132Gi Swap: 0B 0B 0B # ceph-3 free -h total used free shared buff/cache available Mem: 187Gi 37Gi 4.6Gi 4.0Gi 145Gi 144Gi Swap: 0B 0B 0B # ceph-4 free -h total used free shared buff/cache available Mem: 251Gi 31Gi 8.3Gi 231Mi 211Gi 217Gi Swap: 124Gi 3.8Gi 121Gi # ceph-5 free -h total used free shared buff/cache available Mem: 251Gi 32Gi 14Gi 135Mi 204Gi 216Gi Swap: 124Gi 4.0Gi 121Gi # ceph-6 free -h total used free shared buff/cache available Mem: 251Gi 30Gi 16Gi 145Mi 204Gi 218Gi Swap: 124Gi 4.0Gi 121Gi We have configured swap space on all of them, for ceph-mgr nodes, we have 8G swap space and 128G swap configured for osd nodes, and our zabbix has monitored a swap over 50% usage for ceph-1 to ceph-3, but our available space are still around 140G against the total 187G. Just wondering whether the swap space is necessary when we have lots of memory available? Thanks very much for your answering.

Ceph NFS data - cannot read files, getattr returns NFS4ERR_PERM
by Wyll Ingersoll 16 Mar '23

16 Mar '23

ceph pacific 16.2.11 (cephadm managed) I have configured some NFS mounts from the ceph GUI from cephfs. We can mount the filesystems and view file/directory listings, but cannot read any file data. The permissions on the shares are RW. We mount from the client using "vers=4.1". Looking at debug logs from the container running nfs-ganesha, I see the following errors when trying to read a file's content: 15/03/2023 15:27:13 : epoch 6411e209 : gw01 : ganesha.nfsd-7[svc_8] complete_op :NFS4 :DEBUG :Status of OP_READ in position 2 = NFS4ERR_PERM, op response size is 7480 total response size is 7568 15/03/2023 15:27:13 : epoch 6411e209 : gw01 : ganesha.nfsd-7[svc_8] complete_nfs4_compound :NFS4 :DEBUG :End status = NFS4ERR_PERM lastindex = 3 Also, watching the TCP traffic, I see errors in the NFS protocol corresponding to these messages: 11:44:43.745570 IP xxx.747 > gw01.nfs: Flags [P.], seq 24184536:24184748, ack 11409577, win 602, options [nop,nop,TS val 342245425 ecr 2683489461], length 212: NFS request xid 156024373 208 getattr fh 0,1/53 11:44:43.745683 IP gw01.nfs > xxx.747: Flags [P.], seq 11409577:11409677, ack 24184748, win 3081, options [nop,nop,TS val 2683489461 ecr 342245425], length 100: NFS reply xid 156024373 reply ok 96 getattr ERROR: Operation not permitted So there appears to be a permissions problem where nfs-ganesha is not able to "getattr" on cephfs data. The export looks like this (read from rados): EXPORT { FSAL { name = "CEPH"; user_id = "nfs.cephfs.7"; filesystem = "cephfs"; secret_access_key = "xxx"; } export_id = 7; path = "/exports/nfs/foobar"; pseudo = "/foobar"; access_type = "RW"; squash = "no_root_squash"; attr_expiration_time = 0; security_label = false; protocols = 4; transports = "TCP"; } ceph auth permissions for the nfs.cephfs.7 client: [client.nfs.cephfs.7] key = xxx caps mds = "allow rw path=/exports/nfs/foobar" caps mon = "allow r" caps osd = "allow rw pool=.nfs namespace=cephfs, allow rw tag cephfs data=cephfs" Any suggestions?

Re: Stuck OSD service specification - can't remove
by Eugen Block 16 Mar '23

16 Mar '23

Hi, I tried to respond directly in the web ui of the mailing list but my message is queued for moderation. I just wanted to update a solution that worked for me when a service spec is stuck in a pending state, maybe this will help others in the same situation. While playing around with a test cluster I ended up with a "deleting" osd service spec. The SUSE team has an article [1] for this case, the following helped me resolve this issue. I had three different osd specs in place for the same three nodes: ---snip--- osd 3 <deleting> 3w nautilus2;nautilus3 osd.osd-hdd-ssd 3 2m ago 2w nautilus;nautilus2;nautilus3 osd.osd-hdd-ssd-mix 3 2m ago - <unmanaged> ---snip--- I replaced the "service_name" with the more suiting value ("osd.osd-hdd-ssd") in the unit.meta file of each OSD containing the invalid spec, then restarted each affected OSD. It probably wouldn't have been necessary but I wanted to see the effect immediately, so I failed over the mgr (ceph mgr fail), now I only have one valid osd spec. ---snip--- # before nautilus3:~ # grep service_name /var/lib/ceph/201a2fbc-ce7b-44a3-9ed7-39427972083b/osd.3/unit.meta "service_name": "osd", # after nautilus3:~ # grep service_name /var/lib/ceph/201a2fbc-ce7b-44a3-9ed7-39427972083b/osd.3/unit.meta "service_name": "osd.osd-hdd-ssd", nautilus3:~ # ceph orch ls osd NAME PORTS RUNNING REFRESHED AGE PLACEMENT osd.osd-hdd-ssd 9 10m ago 2w nautilus;nautilus2;nautilus3 ---snip--- Regards, Eugen [1] https://www.suse.com/support/kb/doc/?id=000020667

External Auth (AssumeRoleWithWebIdentity) , STS by default, generic policies and isolation by ownership
by Christian Rohmann 16 Mar '23

16 Mar '23

Hello ceph-users, unhappy with the capabilities in regards to bucket access policies when using the Keystone authentication module I posted to this ML a while back - https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/message/S2TV7GVFJT… In general I'd still like to hear how others are making use of external authentication and STS and what your experiences are in replacing e.g. Keystone authentication In the meantime we looked into OIDC authentication (via Keycloak) and the potentials there. While this works in general, AssumeRoleWithWebIdentity comes back with an STS token and that can be used to access S3 buckets, I am wondering about a few things: 1) How to enable STS for everyone (without user-individual policy to AssumeRole) In the documentation on STS (https://docs.ceph.com/en/quincy/radosgw/STS/#sts-in-ceph) and also STS-Lite (https://docs.ceph.com/en/quincy/radosgw/STSLite/#sts-lite) it's implied at one has to attach an dedicated policy to allow for STS to each user individually. This does not scale well with thousands of users. Also when using a federated / external authentication, there is no explicit user creation "A shadow user is created corresponding to every federated user. The user id is derived from the ‘sub’ field of the incoming web token." Is there a way to automatically have a role corresponding to each user that can be assumed via a OIDC token? So an implicit role that would allow for an externally authenticated user to have full access to S3 and all buckets owned? Looking at STS Lite documentation, it seems all the more natural to be able to allow keystone users to make use of STS. Is there any way to apply such an AssumeRole policy "globally" or for a whole set of users at the same time? I just found PR https://github.com/ceph/ceph/pull/44434 aiming to add policy variables such as ${aws:username} to allow for generic policies. But this is more about restricting bucket names or granting access to certain pattern of names. 2) Isolation in S3 Multi-Tenancy with external IdP (AssumeRoleWithWebIdentity), how does bucket ownership come into play? Following the question about generic policies for STS I am wondering about the role (no pun intended) that the bucket ownership or tenant play here? If one creates a role policy of e.g. {"Version":"2012-10-17","Statement":{"Effect":"Allow","Action":"s3:*","Resource":"arn:aws:s3:::*"}} Would this allow someone assuming this role access to all, "*", buckets, or just those owned by the user that created this role policy? In case of Keystone auth the owner of a bucket is the project, not the individual (human) user. So this creates somewhat of a tenant which I'd want to isolate. 3) Allowing users to create their own roles and policies by default Is there a way to allow users to create their own roles and policies to use them by default? All the examples talk about the requirement for admin caps and individual setting of '--caps="user-policy=*'. If there was a default role + policy (question #1) that could be applied to externally authenticated users, I'd like for them to be able to create new roles and policies to grant access to their buckets to other users. Regards Christian

Dear List, Today i was sucessfully upgrading with cephadm from 16.2.8 -> 16.2.9 -> 16.2.10 -> 16.2.11 Now i wanted to upgrade to 17.2.0 but after starting the upgrade with ``` # ceph orch upgrade start --ceph-version 17.2.0 ``` The orch manager module seems to be gone now and the upgrade don't seem to run. ``` # ceph orch upgrade status Error ENOENT: No orchestrator configured (try `ceph orch set backend`) # ceph orch set backend cephadm Error ENOENT: Module not found ``` During the failed upgrade all nodes had the 16.2.11 cephadm installed. Fortunately the cluster is still running... somehow. I installed the latest 17.2.X cephadm on all nodes and rebooted them nodes, but this didn't help. Does someone have a hint? Yours, bbk

Bluestore RocksDB Compression how to set
by Feng, Hualong 16 Mar '23

16 Mar '23

Hi all I want to study the effect of bluestore rocksdb compression on ceph and whether it is necessary to optimize it. But currently, bluestore rocksdb compression is disabled by default in ceph. I simply replaced the rocksdb compression algorithm, and then performed a 4KB rand read fio test, but the test results are not different. So I would like to ask you, is there any scenario where rocksdb needs to be compressed in ceph, and if so, what type of test is used to better demonstrate the impact of rocksdb compression on the upper layer of ceph. // create 10GB image ceph osd pool create rbd 128 rbd pool init rbd rbd create --size 10240 --image rbd/image --image-format 2 --thick-provision //fio [global] ioengine=rbd iodepth=128 rw=randwrite bs=4KB time_based=1 ramp_time=60s runtime=300s clientname=admin pool=rbd group_reporting buffer_compress_percentage=80 refill_buffers buffer_pattern=0xdeadbeef [volumes] rbdname=image numjobs=1 Thanks -Hualong

Ganesha NFS: Files disappearing
by Patrick Schlangen 15 Mar '23

15 Mar '23

Hi, today I saw a strange situation where files which were copied to a cephfs via Ganesha NFS (deployed via cephadm) disappeared from the NFS directory and then did not show up anymore until I restarted the ganesha instance. This could be observed on different NFS client hosts. While the files were not showing, they could still be seen via cephfs-shell, so I assume the issue is somewhere on the NFS side. Interestingly, the folder modification time (shown in ls) matched the time the file was copied to that folder. Any idea what could be the issue here? Unfortunately there were no interesting logs and I couldn't find a way yet to reproduce this. The ceph version in use is 17.2.5. Thanks, Patrick

10x more used space than expected
by Gaël THEROND 15 Mar '23

15 Mar '23

Hi everyone, I’ve got a quick question regarding one of our RadosGW bucket. This bucket is used to store docker registries, and the total amount of data we use is supposed to be 4.5Tb BUT it looks like ceph told us we rather use ~53Tb of data. One interesting thing is, this bucket seems to shard for unknown reason as it is supposed to be disabled by default, but even taking that into account we’re not supposed to see such a massive amount of additional data isn’t it? Here is the bucket stats of it: https://paste.opendev.org/show/bdWFRvNFtxyHnbPfXWu9/

Stuck OSD service specification - can't remove

Has anybody run into a 'stuck' OSD service specification? I've tried to delete it, but it's stuck in 'deleting' state, and has been for quite some time (even prior to upgrade, on 15.2.x). This is on 16.2.3: NAME PORTS RUNNING REFRESHED AGE PLACEMENT osd.osd_spec 504/525 <deleting> 12m label:osd root@ceph01:/# ceph orch rm osd.osd_spec Removed service osd.osd_spec From active monitor: debug 2021-05-06T23:14:48.909+0000 7f17d310b700 0 log_channel(cephadm) log [INF] : Remove service osd.osd_spec Yet in ls, it's still there, same as above. --export on it: root@ceph01:/# ceph orch ls osd.osd_spec --export service_type: osd service_id: osd_spec service_name: osd.osd_spec placement: {} unmanaged: true spec: filter_logic: AND objectstore: bluestore We've tried --force, as well, with no luck. To be clear, the --export even prior to delete looks nothing like the actual service specification we're using, even after I re-apply it, so something seems 'bugged'. Here's the OSD specification we're applying: service_type: osd service_id: osd_spec placement: label: "osd" data_devices: rotational: 1 db_devices: rotational: 0 db_slots: 12 I would appreciate any insight into how to clear this up (without removing the actual OSDs, we're just wanting to apply the updated service specification - we used to use host placement rules and are switching to label-based). Thanks, David

pg wait too long when osd restart
by yite gu 14 Mar '23

14 Mar '23

Hi all, osd_heartbeat_grace = 20 and osd_pool_default_read_lease_ratio = 0.8 by default, so, pg will wait 16s when osd restart in the worst case. This wait time is too long, client i/o can not be unacceptable. I think adjusting the osd_pool_default_read_lease_ratio to lower is a good way. Have any good suggestions about reduce pg wait time？ Best Regard Yite Gu

rbd on EC pool with fast and extremely slow writes/reads
by Andrej Filipcic 14 Mar '23

14 Mar '23

Hi, I have a problem on one of ceph clusters I do not understand. ceph 17.2.5 on 17 servers, 400 HDD OSDs, 10 and 25Gb/s NICs 3TB rbd image is on erasure coded 8+3 pool with 128pgs , xfs filesystem, 4MB objects in rbd image, mostly empy. I have created a bunch of 10G files, most of them were written with 1.5GB/s, few of them were really slow, ~10MB/s, a factor of 100. When reading these files back, the fast-written ones are read fast, ~2-2.5GB/s, the slowly-written are also extremely slow in reading, iotop shows between 1 and 30 MB/s reading speed. This does not happen at all on replicated images. There are some OSDs with higher apply/commit latency, eg 200ms, but there are no slow ops. The tests were done actually on proxmox vm with librbd, but the same happens with krbd, and on bare metal with mounted krbd as well. I have tried to check all OSDs for laggy drives, but they all look about the same. I have also copied entire image with "rados get...", object by object, the strange thing here is that most of objects were copied within 0.1-0.2s, but quite some took more than 1s. The cluster is quite busy with base traffic of ~1-2GB/s, so the speeds can vary due to that. But I would not expect a factor of 100 slowdown for some writes/reads with rbds. Any clues on what might be wrong or what else to check? I have another similar ceph cluster where everything looks fine.

Undo "radosgw-admin bi purge"
by Robert Sander 13 Mar '23

13 Mar '23

Hi, There is an operation "radosgw-admin bi purge" that removes all bucket index objects for one bucket in the rados gateway. What is the undo operation for this? After this operation the bucket cannot be listed or removed any more.

quincy: test cluster on nvme: fast write, slow read
by Arvid Picciani 12 Mar '23

12 Mar '23

Hi, Doing some lab tests to understand why ceph isnt working for us, and here's the first puzzle: setup: A completely fresh quincy cluster, 64 core EPYC 7713, 2 nvme drives > ceph osd crush rule create-replicated osd default osd ssd > ceph osd pool create rbd replicated osd --size 2 > dd if=/dev/rbd0 of=/tmp/testfile status=progress bs=4M count=1000 4194304000 bytes (4.2 GB, 3.9 GiB) copied, 7.0152 s, 598 MB/s > dd of=/dev/rbd0 if=/tmp/testfile status=progress bs=4M count=1000 4194304000 bytes (4.2 GB, 3.9 GiB) copied, 3.82156 s, 1.1 GB/s write performance is 1/3 of raw nvme, which i suppose is expected (not very good tho) but why is read performance so bad? top shows only one core is being utilized at 40% cpu. it can't be network either, since this is all localhost. thanks Arvid -- +4916093821054

pg wait too long when osd restart
by yite gu 10 Mar '23

10 Mar '23

Hi all, osd_heartbeat_grace = 20 and osd_pool_default_read_lease_ratio = 0.8 by default, so, pg will wait 16s when osd restart in the worst case. This wait time is too long, client i/o can not be unacceptable. I think adjusting the osd_pool_default_read_lease_ratio to lower is a good way. Have any good suggestions about reduce pg wait time？ Best Regard Yite Gu

restoring ceph cluster from osds
by Ben 09 Mar '23

09 Mar '23

Hi, I ended up with having whole set of osds to get back original ceph cluster. I figured out to make the cluster running. However, it's status is something as below: bash-4.4$ ceph -s cluster: id: 3f271841-6188-47c1-b3fd-90fd4f978c76 health: HEALTH_WARN 7 daemons have recently crashed 4 slow ops, oldest one blocked for 35077 sec, daemons [mon.a,mon.b] have slow ops. services: mon: 3 daemons, quorum a,b,d (age 9h) mgr: b(active, since 14h), standbys: a osd: 4 osds: 0 up, 4 in (since 9h) data: pools: 0 pools, 0 pgs objects: 0 objects, 0 B usage: 0 B used, 0 B / 0 B avail pgs: All osds are down. I checked the osds logs and attached with this. Please help and I wonder if it's possible to get the cluster back. I have some backup for monitor's data. Till now I haven't restore that in the course. Thanks, Ben

Trying to throttle global backfill
by Rice, Christian 09 Mar '23

09 Mar '23

I have a large number of misplaced objects, and I have all osd settings to “1” already: sudo ceph tell osd.\* injectargs '--osd_max_backfills=1 --osd_recovery_max_active=1 --osd_recovery_op_priority=1' How can I slow it down even more? The cluster is too large, it’s impacting other network traffic 😉

In the same time we've had >20k PUT requests the were working fine on other buckets. This error also seem to happen to other buckets, but only very sporadically. Did someone encounter this issue or knows what it could be? Cheers Boris

LRC k6m3l3, rack outage and availability
by steve.bakerx1＠gmail.com 09 Mar '23

09 Mar '23

Hi, currently we are testing LRC codes and I got a cluster setup with 3 racks and 4 hosts in each of those. What I want to achieve is to have a storage efficient erasure code (<=200%) and also availability during a rack outage. In (my) theory, that should have worked with the LRC k6m3l3 having a crush-locality=rack and a crush-failure domain=host. But when I tested it, the PGs of the pool all go in the "down" state. So, when we've got k=6 data chunks and m=3 coding chunks, the data should be reconstructable with 6 of these 9 objects. With l=3, LRC splits these 9 objects in 3 groups of 3 objects and creates one additional locality-chunk per group. We now got 3 groups of 4 objects. These 3 groups get distributed over the 3 racks, the 4 objects of each group get distributed over the 4 hosts of a rack. I thought that on a full rack outage, the 6 remaining k/m chunks on the other 2 racks should still be enough to keep up the availability and the cluster could proceed in a degraded state. But it does not, so I guess my thinking is wrong :) I wonder what's the reason for this, is it maybe some min_size setting ? The default min_size of this pool becomes 7 - I also changed that to 6 (yes, one shouldn't do that in productrion I think) but got the same result. Below I've added some details about the cluster, pool creation and pg dumps. Any ideas ? Can s.o. explain why this does not work or give another solution how to achieve the described specifications?

Error deploying Ceph Qunicy using ceph-ansible 7 on Rocky 9
by wodel youchi 09 Mar '23

09 Mar '23

Hi, I am trying to deploy Ceph Quincy using ceph-ansible on Rocky9. I am having some problems and I don't know where to search for the reason. PS : I did the same deployment on Rocky8 using ceph-ansible for the Pacific version on the same hardware and it worked perfectly. I have 03 controllers nodes : mon, mgr, mdss and rgws and 27 osd nodes : with 04 nvme disks (osd) each I am using a 10Gb network with jumbo frames. The deployment starts with no issues, the 03 monitors are created correctly, then the 03 managers are created, after that the OSD are prepared and formatted, until here everything is working fine, but when the "*wait for all osd to be up*" task is launched, which means starting all OSDs containers in all OSD nodes, things go south, the monitors become out of quorum, ceph -s takes a lot of time to respond and not all OSDs are being activated, and the deployment fails at the end. cluster 2023-03-06T12:00:26.431947+0100 mon.controllera (mon.0) 3864 : cluster [WRN] [WRN] MON_DOWN: 1/3 mons down, quorum controllera,controllerc cluster 2023-03-06T12:00:26.431953+0100 mon.controllera (mon.0) 3865 : cluster [WRN] mon.controllerb (rank 1) addr [v2: 20.1.0.27:3300/0,v1:20.1.0.27:6789/0] is down (out of quorum) The monitor container in 2 of my controllers nodes stays at 100% of cpu utilization.

Difficulty with rbd-mirror on different networks.
by Murilo Morais 08 Mar '23

08 Mar '23

Good evening everyone. I'm having trouble with rbd-mirror. In test environment I have the following scenario: DC1: public_network: 172.20.0.0/24, 192.168.0.0/24 --mon-ip 172.20.0.1 ip: 192.168.0.1 DC2: public_network: 172.21.0.0/24, 192.168.0.0/24 --mon-ip 172.21.0.1 ip 192.168.0.2 If I add the peer as being from the 192.168.0.0/24 network, the mirror does not work, both machines see each other, if I add a machine within the same block as the other (the first public_network network of each), that is, DC1 with 172.21.0.2/24 and DC2 with 172.20.0.2/24, the mirror works. Why can't I make the mirror work on the 192.168.0.0/24 network? Thank you very much in advance.

Dashboard for Object Servers using wrong hostname
by Wyll Ingersoll 08 Mar '23

08 Mar '23

I have an ochestrated (cephadm) ceph cluster (16.2.11) with 2 radosgw services on 2 separate hosts without HA (i.e. no ingress/haproxy in front). Both of the rgw servers use SSL and have a properly signed certificate. We can access them with standard S3 tools like s3cmd, cyberduck, etc. The problem seems to be that the the Ceph mgr dashboard fails to access the RGW API because it uses the shortname "gw01" instead of the FQDN "gw01.domain.com" when forming the S3 signature which makes the S3 signature check fail and we get the following error: Error connecting to Object Gateway: RGW REST API failed request with status code 403 (b'{"Code":"SignatureDoesNotMatch","RequestId":"tx00000521ceca28974e94b-006408e' b'f93-454bbb4e-default","HostId":"454bbb4e-default-default"}') It seems that the ceph mgr (which we have restarted several times) uses just the short hostname from the inventory and I don't see how to tell it to use the FQDN. Neither is it possible to configure the RGW to listen on an alternate non-SSL port on the cluster private network since the service spec for RGW only allows to set the rgw_frontend_port and rgw_frontend_type, but not the full frontend spec (which would allow for multiple listeners). When we did have HA (haproxy) ingress configured, we ran into issues with the user clients getting lots of 503 errors due to some interaction between the RGW and the haproxy so we gave up on that config and now talk directly to the RGW over SSL which is working well. Any suggestions? thanks, Wyllys Ingersoll

Problem with cephadm and deploying 4 ODSs on nvme Storage
by claas.goltz＠contact-software.com 08 Mar '23

08 Mar '23

Hi Community, currently i’m installing an nvme only storage cluster with cephadm from scratch (v.17.2.5). Everything works fine. Each of my nodes (6) has 3 enterprise nvme’s with 7TB capacity. At the beginning I only installed one OSD per nvme, now I want to use four instead of one but I’m struggling with that. Frist of all I set the following option in my cluster: ceph orch apply osd --all-available-devices --unmanaged=true As I understand this option should prevent cephadm to automatically fetch new, available disks and deploying OSD daemons. But that seems not to work. If I delete and purge my OSD and zapping the disk with ceph orch device zap ceph-nvme01 /dev/nvme2n1 –force the disk came available for the cluster and seconds later it deploys the same OSD ID than it has before. I checked that the old OSD was completely removed and the docker container was not started. My next try was to set: ceph orch host label add ceph-nvme01 _no_schedule purge the OSD zapping the disk and following: ceph orch daemon add osd ceph-nvme01:/dev/nvme2n1,osds_per_device=4 removing the _no_schedule flag and again: the old OSD was recreated and not 4. So where is my mistake? Thank you!

Upgrade problem from 1.6 to 1.7
by Oğuz Yarımtepe 08 Mar '23

08 Mar '23

Hi, I have a cluster with rook operator running the ceph version 1.6 and upgraded first rook operator and then the ceph cluster definition. Everything was fine, every component except from osds are upgraded. Below is the reason of OSD not being upgraded: not updating OSD 1 on node "some-node-name". node no longer exists in the storage spec. if the user wishes to remove OSDs from the node, they must do so manually. Rook will not remove OSDs from nodes that are removed from the storage spec in order to prevent accidental data loss Any idea or anyone had seen it before? Regards.

Issue upgrading 17.2.0 to 17.2.5
by aellahib＠gmail.com 07 Mar '23

07 Mar '23

I initially ran the upgrade fine but it failed @ around 40/100 on an osd, so after waiting for along time i thought I'd try restarting it and then restarting the upgrade. I am stuck with the below debug error, I have tested docker pull from other servers and they dont fail for the ceph images but on ceph it does. If i even try to redeploy or add or remove mon damons for example it comes up with the same error related to the images. The error that ceph is giving me is: 2023-03-02T07:22:45.063976-0700 mgr.mgr-node.idvkbw [DBG] _run_cephadm : args = [] 2023-03-02T07:22:45.070342-0700 mgr.mgr-node.idvkbw [DBG] args: --image stop --no-container-init pull 2023-03-02T07:22:45.081086-0700 mgr.mgr-node.idvkbw [DBG] Running command: which python3 2023-03-02T07:22:45.180052-0700 mgr.mgr-node.idvkbw [DBG] Running command: /usr/bin/python3 /var/lib/ceph/5058e342-dac7-11ec-ada3-01065e90228d/cephadm.059bfc99f5cf36ed881f2494b104711faf4cbf5fc86a9594423cc105cafd9b4e --image stop --no-container-init pull 2023-03-02T07:22:46.500561-0700 mgr.mgr-node.idvkbw [DBG] code: 1 2023-03-02T07:22:46.500787-0700 mgr.mgr-node.idvkbw [DBG] err: Pulling container image stop...

Re: Very slow backfilling
by Joffrey 07 Mar '23

07 Mar '23

My Ceph Version is 17.2.5 and all configuration about osd_scrub* are defaults. I tried some updates on osd-max-backfills but no change. I have many HDD with NVME for db and all are connected in a 25G network. Yes, it's the same PG since 4 days. I got a failure on a HDD and get many days of recovery+backfilling last 2 weeks.

Theory about min_size and its implications
by stefan.pinter＠bearingpoint.com 06 Mar '23

06 Mar '23

Hi! it is unclear for us what min_size means besides what it does. i hope someone can clear this up :) scenario: size is 3 and min_size is 2 2 rooms with 100 OSDs each and this crush rule "op": "take", "item": -10, "item_name": "default" "op": "choose_firstn", "num": 2, "type": "room" "op": "chooseleaf_firstn", "num": 2, "type": "host" "op": "emit" so if one room goes down/offline, around 50% of the PGs would be left with only 1 replica making them read-only. if we'd set min_size to 1 and one room goes down, user wouldn't still be able to access all PGs - but what is the problem with only one active PG? someone pointed out "split brain" but I am unsure about this. i think what happens in the worst case is this: only 1 PG is available, client writes changes to this PG, the disk of this 1 PG dies as well - so i guess we'd need to restore the data from the 2 offline PGs in the room that is down and we would have lots of trouble with restoring and also with data inconsistency, right? thank you!

We got rid of the errors, but the Openshift cluster did not want to work with the old persistence volumes. The pods wrote an error that they could not find it, while it was present and moreover, this volume was associated with pvc. Now we have rolled back the cluster and are trying to remove the mds error. Any ideas what to try? Thanks

orchestrator issues on ceph 16.2.9
by Adrian Nicolae 06 Mar '23

06 Mar '23

Hi, I have some orchestrator issues on our cluster running 16.2.9 with rgw only services. We first noticed these issues a few weeks ago when adding new hosts to the cluster - the orch was not detecting the new drives to build the osd containers for them. Debugging the mgr logs, I noticed that the mgr was crashing due to the dashboard module. I disabled the dashboard module and the new drives were detected and added to the cluster. Now we have other similar issues : we have a failed drive. The failure was detected , the osd was marked as down and the rebalancing is finished. I want to remove the failed osd from the cluster but it looks like the orch is not working : - I launched the osd removal with 'ceph orch osd rm 92 --force' where 92 is the osd id in question - I checked the progress but nothing happens even after a few days : ceph orch osd rm status OSD HOST STATE PGS REPLACE FORCE ZAP DRAIN STARTED AT *92 node10 started 0 False True False* - the osd process is stopped on that host and from the orch side I can see this : ceph orch ps --daemon_type osd --daemon_id 92 NAME HOST PORTS STATUS REFRESHED AGE MEM USE MEM LIM VERSION IMAGE ID osd.92 node10 error 11h ago 4w - 4096M <unknown> <unknown> - I have the same long refresh interval on other osds as well. I know it should be 10 minutes or so : NAME HOST PORTS STATUS REFRESHED AGE MEM USE MEM LIM VERSION IMAGE ID CONTAINER ID osd.93 node09 running (4w) 11h ago 4w 5573M 4096M 16.2.9 3520ead5eb19 d2f658e9e37b osd: *116 osds: 115 up* (since 11d), 115 in (since 11d) 90 hdd 16.37109 1.00000 16 TiB 4.0 TiB 4.0 TiB 0 B 17 GiB 12 TiB 24.66 0.97 146 up * 92 hdd 0 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 0 down* 94 hdd 16.37109 1.00000 16 TiB 4.0 TiB 4.0 TiB 0 B 17 GiB 12 TiB 24.66 0.97 146 up - I activated debug 20 on the mgr but I can't see any errors or other clues regarding the osd removal. I also switched to the standby manager with 'ceph mgr fail'. The mgr switch works but still nothing happens - It's not only the osd removal thing. I also tried to deploy new rgw services by applying rgw labels on 2 new hosts , we have specs for building rgw containers when detecting the label. Again, nothing happens. I'm planning to upgrade to 16.2.11 to see if this solves the issues but I'm not very confident, I didn't see anything regarding this in the changelogs. Is there anything else I can try to debug this issue ? Thanks.

Hi, I ended up with having whole set of osds to get back original ceph cluster. I figured out to make the cluster running. However, it's status is something as below: bash-4.4$ ceph -s cluster: id: 3f271841-6188-47c1-b3fd-90fd4f978c76 health: HEALTH_WARN 7 daemons have recently crashed 4 slow ops, oldest one blocked for 35077 sec, daemons [mon.a,mon.b] have slow ops. services: mon: 3 daemons, quorum a,b,d (age 9h) mgr: b(active, since 14h), standbys: a osd: 4 osds: 0 up, 4 in (since 9h) data: pools: 0 pools, 0 pgs objects: 0 objects, 0 B usage: 0 B used, 0 B / 0 B avail pgs: All osds are down. I checked the osds logs following this. Please help and I wonder if it's possible to get the cluster back. I have some backup for monitor's data. Until now I haven't restored that in the course. Thanks, Ben osd0 log: debug 2023-03-04T04:41:50.620+0000 7f824d7043c0 0 set uid:gid to 167:167 (ceph:ceph) debug 2023-03-04T04:41:50.620+0000 7f824d7043c0 0 ceph version 17.2.5

The conditional policy for the List operations does not work as expected for the bucket with tenant.
by Dmitry Kvashnin 04 Mar '23

04 Mar '23

The conditional policy for the List operations does not work as expected for the bucket with tenant. With buckets and users without a tenant, everything is fine. The owner of t1\bucket1 is t1$user1. Bucket Policy: { "Version":"2012-10-17", "Statement":[ { "Sid":"PolicyForUser2Prefix", "Effect":"Allow", "Principal":{"AWS": ["arn:aws:iam::t1:user/user2"] }, "Action": ["s3:List*","s3:Get*"], "Condition" : { "StringLike" : { "s3:prefix": [ "obj*"], "s3:delimiter":["/"] } }, "Resource": [ "arn:aws:s3::t1:bucket1", "arn:aws:s3::t1:bucket1/obj*" ] } ] } t1$user2 can list bucket1\obj1 but can't get bucket1\obj1 Get returns Error403 If the "Condition" section is removed from the policy, t1$user2 can get obj1 but can't list. If I change the condition to "StringLikeIfExists", everything is fine, but t1$user2 can List the root of the bucket1, which is undesirable. Are there any errors in the policy or is it a bug?

ceph quincy nvme drives displayed in device list sata ssd not displayed
by Chris Brown 03 Mar '23

03 Mar '23

Hello, Setting up first ceph cluster in lab. Rocky 8.6 Ceph quincy Using curl install method Following cephadm deployment steps Everything works as expected except ceph orch device ls --refresh Only displays nvme devices and not the sata ssds on the ceph host. Tried sgdisk --zap-all /dev/sda wipefs -a /dev/sda Adding sata osd manually I get: ceph orch daemon add osd ceph-a:data_devices=/dev/sda Created no osd(s) on host ceph-a; already created? nvme osd gets added without issue. I have looked in the volume log on the node and monitor log on the admin server and have not seen anything that seems like an obvious clue. I can see commands running successfully against /dev/sda in the logs. Ideas? Thanks, cb

RGW Multisite archive zone bucket removal restriction
by Ondřej Kukla 03 Mar '23

03 Mar '23

Hello, I’m planning a Ceph multisite deployment with two clusters. One being a primary one the clients will be intereacting with and a second one with zone tier type set as an archive one. There is also a one way sync from the primary zone set - I would like to have this cluster as a "backup zone”. The setup works as expected for me, but with one exception. When I delete a bucket on the primary zone the bucket in the archive zone gets also deleted which is a issue as I would like to be able to restore the bucket in case of unintentional deletion on the primary zone. I know that there is the object lock, but I would like to know if there is some other way? I would imagine for example a situation where when the bucket is removed on the primary zone the bucket on the archive zone would be marked as to be removed in some time period like 1day or 1week or something. Your thoughts are much appreciated. Kind regards, Ondrej

Minimum client version for Quincy
by Massimo Sgaravatto 03 Mar '23

03 Mar '23

Dear all I am going to update a ceph cluster (where I am using only rbd and rgw, i.e. I didn't deploy cephfs) from Octtopus to Quincy Before doing that I would like to understand if some old nautilus clients (that I can't update for several reasons) will still be able to connect In general: I am not able to find this information in the documentation of any ceph release Should I refer to get-require-min-compat-client ? Now in my Octopus cluster I see: [root@ceph-mon-01 ~]# ceph osd get-require-min-compat-client luminous but I have the feeling that this value is simply the one I set a while ago to support the upmap feature Thanks, Massimo

3 node clusters and a corner case behavior
by Victor Rodriguez 03 Mar '23

03 Mar '23

Hello, Before we start I'm fully aware that this kind of setup is not recommended by any means and I'm familiar with it's implications. I'm just trying to practice extreme situations, just in case... I have a test cluster with: 3 nodes with Proxmox 7.3 + Ceph Quincy 17.2.5 3 monitors + 3 managers in server01, server02 and server03 4 OSD, two in server01, two in server02. No OSD in server03. All OSD are class "ssd". 1 pool with replica=2, min_replica=1. Crush rule uses just ssd class OSD. I do wait for ceph status to be fully OK between each test. A.- If I orderly shutdown server01, it's OSDs get marked down as expected. I/O on the pool works correctly before, during and after the shutdown. B.- If I poweroff server01, it's OSDs do not get marked down. I/O on the pool does not work at all, neither reads nor writes. A small number of slow-ops show in ceph status, something like 7 to 25. After 30 minutes, the server01's OSDs get marked down, I/O on the pool gets restored and slow-ops disappear. C.- Now I create an OSD on server03 with class "noClass". This OSD won't be used by the pool. If I now poweroff server01, it's OSDs get marked down as soon as some I/O is sent to the pool and I/O works correctly. Looks like I am in this exact situation: https://tracker.ceph.com/issues/16910#note-2 Questions: Why does Ceph behave this way in test B? Shouldn't it simply mark the OSDs down like in test A and C? Which config setting(s) set that 30 minute wait time before marking all OSD down? Many thanks in advance! --

Interruption of rebalancing
by Jeffrey Turmelle 02 Mar '23

02 Mar '23

I have a Nautilus cluster with 7 nodes, 210 HDDs. I recently added the 7th node with 30 OSDs which are currently rebalancing very slowly. I just noticed that the ethernet interface only negotiated a 1Gb connection, even though it has a 10Gb interface. I’m not sure why, but would like to reboot the node to get the interface back to 10Gb. Is it ok to do this? What should I do to prep the cluster for the reboot?

Very slow backfilling

Hi, I have many 'not {deep-}scrubbed in time' and a1 PG remapped+backfilling and I don't understand why this backfilling is taking so long. root@hbgt-ceph1-mon3:/# ceph -s cluster: id: c300532c-51fa-11ec-9a41-0050569c3b55 health: HEALTH_WARN 15 pgs not deep-scrubbed in time 13 pgs not scrubbed in time services: mon: 3 daemons, quorum hbgt-ceph1-mon1,hbgt-ceph1-mon2,hbgt-ceph1-mon3 (age 36h) mgr: hbgt-ceph1-mon2.nteihj(active, since 2d), standbys: hbgt-ceph1-mon1.thrnnu, hbgt-ceph1-mon3.gmfzqm osd: 60 osds: 60 up (since 13h), 60 in (since 13h); 1 remapped pgs rgw: 3 daemons active (3 hosts, 2 zones) data: pools: 13 pools, 289 pgs objects: 67.74M objects, 127 TiB usage: 272 TiB used, 769 TiB / 1.0 PiB avail pgs: 288 active+clean 1 active+remapped+backfilling io: client: 3.3 KiB/s rd, 1.5 MiB/s wr, 3 op/s rd, 8 op/s wr recovery: 790 KiB/s, 0 objects/s What can I do to understand this slow recovery (is it the backfill action ?)

ceph 16.2.10 - misplaced object after changing crush map only setting hdd class
by xadhoom76＠gmail.com 02 Mar '23

02 Mar '23

Hi to all and thanks for sharing your experience on ceph ! We have an easy setup with 9 osd all hdd and 3 nodes, 3 osd for each node. We started the cluster to test how it works with hdd with default and easy bootstrap . Then we decide to add ssd and create a pool to use only ssd. In order to have pools on hdd and pools on ssd only we edited the crushmap to add class hdd We do not enter anything about ssd till now, nor disk or rules only add the class map to the default rule. So i show you the rules before introducing class hdd # rules rule replicated_rule { id 0 type replicated min_size 1 max_size 10 step take default step chooseleaf firstn 0 type host step emit } rule erasure-code { id 1 type erasure min_size 3 max_size 4 step set_chooseleaf_tries 5 step set_choose_tries 100 step take default step chooseleaf indep 0 type host step emit } rule erasure2_1 { id 2 type erasure min_size 3 max_size 3 step set_chooseleaf_tries 5 step set_choose_tries 100 step take default step chooseleaf indep 0 type host step emit } rule erasure-pool.meta { id 3 type erasure min_size 3 max_size 3 step set_chooseleaf_tries 5 step set_choose_tries 100 step take default step chooseleaf indep 0 type host step emit } rule erasure-pool.data { id 4 type erasure min_size 3 max_size 3 step set_chooseleaf_tries 5 step set_choose_tries 100 step take default step chooseleaf indep 0 type host step emit } And here is the after # rules rule replicated_rule { id 0 type replicated min_size 1 max_size 10 step take default class hdd step chooseleaf firstn 0 type host step emit } rule erasure-code { id 1 type erasure min_size 3 max_size 4 step set_chooseleaf_tries 5 step set_choose_tries 100 step take default class hdd step chooseleaf indep 0 type host step emit } rule erasure2_1 { id 2 type erasure min_size 3 max_size 3 step set_chooseleaf_tries 5 step set_choose_tries 100 step take default class hdd step chooseleaf indep 0 type host step emit } rule erasure-pool.meta { id 3 type erasure min_size 3 max_size 3 step set_chooseleaf_tries 5 step set_choose_tries 100 step take default class hdd step chooseleaf indep 0 type host step emit } rule erasure-pool.data { id 4 type erasure min_size 3 max_size 3 step set_chooseleaf_tries 5 step set_choose_tries 100 step take default class hdd step chooseleaf indep 0 type host step emit } Just doing this triggered the misplaced of all pgs bind to EC pool. Is that correct ? and why ? Best regards Alessandro Bolgia

How do I troubleshoot radosgw errors STS?
by mat＠hazmat.dev 02 Mar '23

02 Mar '23

I've setup RadosGW with STS ontop of my ceph cluster. It works great and fine but I'm also trying to setup authentication with an OpenIDConnect provider. I'm have a hard time troubleshooting issues because the radosgw log file doesn't have much information in it. For example when I try to use the `sts:AssumeRoleWithWebIdentity` API it fails with `{'Code': 'AccessDenied', ...}` and all I see is the beat log showing an HTTP 403. Is there a way to enable more verbose logging so I can see what is failing and why I'm getting certain errors with STS, S3, or IAM apis? My ceph.conf looks like this for each node (mildly redacted): ``` [client.radosgw.pve4] host = pve4 keyring = /etc/pve/priv/ceph.client.radosgw.keyring log file = /var/log/ceph/client.radosgw.$host.log rgw_dns_name = s3.lab rgw_frontends = beast endpoint=0.0.0.0:7480 ssl_endpoint=0.0.0.0:443 ssl_certificate=/etc/pve/priv/ceph/s3.lab.crt ssl_private_key=/etc/pve/priv/ceph/s3.lab.key rgw_sts_key = 1111111111111111 rgw_s3_auth_use_sts = true rgw_enable_apis = s3, s3website, admin, sts, iam ```

PG Sizing Question
by Deep Dish 01 Mar '23

01 Mar '23

Hello Looking to get some official guidance on PG and PGP sizing. Is the goal to maintain approximately 100 PGs per OSD per pool or for the cluster general? Assume the following scenario: Cluster with 80 OSD across 8 nodes; 3 Pools: - Pool1 = Replicated 3x - Pool2 = Replicated 3x - Pool3 = Erasure Coded 6-4 Assuming the well published formula: Let (Target PGs / OSD) = 100 [ (Target PGs / OSD) * (# of OSDs) ] / (Replica Size) - Pool1 = (100*80)/3 = 2666.67 => 4096 - Pool2 = (100*80)/3 = 2666.67 => 4096 - Pool3 = (100*80)/10 = 800 => 1024 Total cluster would have 9216 PGs and PGPs. Are there any implications (performance / monitor / MDS / RGW sizing) with how many PGs are created on the cluster? Looking for validation and / or clarification of the above. Thank you.

RadosGW multipart fragments not being cleaned up by lifecycle policy on Quincy
by Sean Houghton 01 Mar '23

01 Mar '23

The latest version of quincy seems to be having problems cleaning up multipart fragments from canceled uploads. The bucket is empty: % s3cmd -c .s3cfg ls s3://warp-benchmark % However, it's got 11TB of data and 700k objects. # radosgw-admin bucket stats --bucket=warp-benchmark { "bucket": "warp-benchmark", "num_shards": 10, "tenant": "", "zonegroup": "6be863e8-a9f2-42c9-b114-c8651b1f1afa", "placement_rule": "ssd.ec63", "explicit_placement": { "data_pool": "", "data_extra_pool": "", "index_pool": "" }, "id": "aa099b5e-01d5-4394-b287-df99a4d63298.18924.1", "marker": "aa099b5e-01d5-4394-b287-df99a4d63298.37403.1", "index_type": "Normal", "owner": "warp_benchmark", "ver": "0#5580404,1#5593184,2#5586262,3#5591427,4#5591937,5#5588120,6#5589760,7#5582923,8#5579062,9#5578699", "master_ver": "0#0,1#0,2#0,3#0,4#0,5#0,6#0,7#0,8#0,9#0", "mtime": "0.000000", "creation_time": "2023-02-10T21:45:12.721604Z", "max_marker": "0#,1#,2#,3#,4#,5#,6#,7#,8#,9#", "usage": { "rgw.main": { "size": 12047620866048, "size_actual": 12047620866048, "size_utilized": 12047620866048, "size_kb": 11765254752, "size_kb_actual": 11765254752, "size_kb_utilized": 11765254752, "num_objects": 736113 } }, "bucket_quota": { "enabled": false, "check_on_raw": false, "max_size": -1, "max_size_kb": 0, "max_objects": -1 } } A bucket list shows that they are all multipart fragments # radosgw-admin bucket list --bucket=warp-benchmark [ ...

Running a gc pass also has no effect # radosgw-admin gc list [] # radosgw-admin gc process # radosgw-admin gc list [] Any ideas?
