Re: Reef - what happened to OSD spec?

Thanks Eugen for following up. Sorry my second response was incomplete. I can confirm that it works as expected too. My confusion was that the section from the online documentation seemed to be missing/moved, and when it initially failed I wrongly thought that the OSD-add process had changed in the Reef release. There might still need to be a way that "destroy" does additional clean-up to clear remnants of LVM fingerprints on the devices as this tripped me up when the OSDspec apply failed due to "filesystem on device" checks. Documentation has been improved and OSD spec is now under this heading for Reef: https://docs.ceph.com/en/reef/cephadm/services/osd/#advanced-osd-service-sp…

Multisite RGW setup not working when following the docs step by step
by Petr Bena 30 Aug '23

30 Aug '23

Hello, My goal is to setup multisite RGW with 2 separate CEPH clusters in separate datacenters, where RGW data are being replicated. I created a lab for this purpose in both locations (with latest reef ceph installed using cephadm) and tried to follow this guide: https://docs.ceph.com/en/reef/radosgw/multisite/ Unfortunatelly, even after multiple attempts it always failed when creating a secondary zone. I could succesfully pull the realm from master, but that was pretty much the last trully succesful step. I can notice that immediately after pulling the realm to secondary, radosgw-admin user list returns an empty list (which IMHO should contain replicated user list from master). Continuing by setting default real and zonegroup and creating the secondary zone in secondary cluster I end up having 2 zones in each cluster, both seemingly in same zonegroup, but with replication failing - this is what I see in sync status: (master) [ceph: root@ceph-lab-brn-01 /]# radosgw-admin sync status realm d2c4ebf9-e156-4c4e-9d56-3fff6a652e75 (ceph) zonegroup abc3c0ae-a84d-48d4-8e78-da251eb78781 (cz) zone 97fb5842-713a-4995-8966-5afe1384f17f (cz-brn) current time 2023-08-30T12:58:12Z zonegroup features enabled: resharding disabled: compress-encrypted metadata sync no sync (zone is master) 2023-08-30T12:58:13.991+0000 7f583a52c780 0 ERROR: failed to fetch datalog info data sync source: 13a8c663-b241-4d8a-a424-8785fc539ec5 (cz-hol) failed to retrieve sync info: (13) Permission denied (secondary) [ceph: root@ceph-lab-hol-01 /]# radosgw-admin sync status realm d2c4ebf9-e156-4c4e-9d56-3fff6a652e75 (ceph) zonegroup abc3c0ae-a84d-48d4-8e78-da251eb78781 (cz) zone 13a8c663-b241-4d8a-a424-8785fc539ec5 (cz-hol) current time 2023-08-30T12:58:54Z zonegroup features enabled: resharding disabled: compress-encrypted metadata sync failed to read sync status: (2) No such file or directory 2023-08-30T12:58:55.617+0000 7ff37c9db780 0 ERROR: failed to fetch datalog info data sync source: 97fb5842-713a-4995-8966-5afe1384f17f (cz-brn) failed to retrieve sync info: (13) Permission denied In master there is one user created during the process (synchronization-user), on slave there are no users and when I try to re-create this synchronization user it complains I shouldn't even try and instead execute the command on master. I can see same realm and zonegroup IDs on both sides, zone list is different though: (master) [ceph: root@ceph-lab-brn-01 /]# radosgw-admin zone list { "default_info": "97fb5842-713a-4995-8966-5afe1384f17f", "zones": [ "cz-brn", "default" ] } (secondary) [ceph: root@ceph-lab-hol-01 /]# radosgw-admin zone list { "default_info": "13a8c663-b241-4d8a-a424-8785fc539ec5", "zones": [ "cz-hol", "default" ] } The permission denied error is puzzling me - could it be because real pull didn't sync the users? I tried this multiple times with clean ceph install on both sides - and always ended up the same. I even tried force creating the same user with same secrets on the other side, but it didn't help. How can I debug what kind of secret is secondary trying to use when communicating with master? Could it be that this multisite RGW setup is not yet truly supported in reef? I noticed that the documentation itself seems written for older ceph versions, as there are no mentions about orchestrator (for example in steps where configuration files of RGW need to be edited, which is done differently when using cephadm). I think that documentation is simply wrong at this time. Either it's missing some crucial steps, or it's outdated or otherwise unclear - simply by following all the steps as outlined there, you are likely to end up the same. Thanks for help!

radosgw mulsite multi zone configuration: current period realm name not same as in zonegroup
by Adiga, Anantha 30 Aug '23

30 Aug '23

Hi, I have a multi zone configuration with 4 zones. While adding a secondary zone, getting this error: root@cs17ca101ja0702:/# radosgw-admin realm pull --rgw-realm=global --url=http://10.45.128.139:8080 --default --access-key=sync_user --secret=sync_secret request failed: (13) Permission denied If the realm has been changed on the master zone, the master zone's gateway may need to be restarted to recognize this user. root@cs17ca101ja0702:/# The realm name is "global". Is the cause of the error due to the primary cluster having a current period listing the realm name as "default" instead of "global" ? However, the realm id is of realm "global" AND the zonegroup does not list realm name but has the correct realm id. See below. How to fix this issue. root@fl31ca104ja0201:/# radosgw-admin realm get { "id": "3da7b5ea-c44b-4d44-aced-fae2aabce97b", "name": "global", "current_period": "b8bc1187-2a2d-4d9e-b7be-c4f4667e3fa6",

Is there any way to fine tune peering/pg relocation/rebalance?
by Szabo, Istvan (Agoda) 30 Aug '23

30 Aug '23

Hello, Is there a way to somehow fine tune the rebalance even further than basic tuning steps when adding new osds? Today I've added some osd to the index pool and it generated many slow ops due to OSD op latency increase + read operation latency increase = high put get latency. https://ibb.co/album/9mN6GQ osd max backfill, max recovery, recovery ops priority are 1. 1 nvme drive has 4 osd, each osd has around 80pg. The steps how I add the osds: 1. Set norebalance 2. add the osds 3. wait for peering 4. unset rebalance It takes like 15-20 mins to became normal without interrupting the rebalance the user traffic.

hardware setup recommendations wanted
by Kai Zimmer 29 Aug '23

29 Aug '23

Dear listers, my employer already has a production Ceph cluster running but we need a second one. I just wanted to ask your opininion on the following setup. It is planned for 500 TB net capacity, expandable to 2 PB. I expect the number of OSD servers to double in the next 4 years. Erasure Code 3:2 will be used for OSDs. Usage will be file storage, Rados block devices and S3: 5x OSD servers (12x18 TB Toshiba MG09SCA18TE SAS spinning disks for data, 2x512 GB Samsung PM9A1 M.2 NVME SSD 0,55 DWPD for system, 1xAMD 7313P CPU with 16 cores @3GHz, 256 GB RAM, LSI SAS 9500 HBA, Broadcom P425G network adapter 4x25 Gbit/s) 3x MON servers (1x2 TB Samsung PM9A1 M.2 NVME SSD 0,55 DWPD for system, 2x1.6TB Kioxia CD6-V SSD 3.0 DWPD for data, 2x Broadcom P210/N210 network 4x10 GBit/s, 1xAMD 7232P CPU with 8 cores @3.1 GHz, 64 GB RAM) 3x MDS servers (1x2 TB Samsung PM9A1 M.2 NVME SSD 0,55 DWPD for system, 2x1.6 TB Kioxia CD6-V SSD 3.0 DWPD for data, 2x Broadcom P210/N210 network 4x10 GBit/s, 1xAMD 7313P CPU with 16 cores @3 GHz, 128 GB RAM) OSD servers will be connected via 2x25 GBit fibre interfaces "backend" to 2x Mikrotik CRS518-16XS-2XQ (which are connected for high-availability via 100 GBit) For the "frontend" connection to servers/clients via 2x10 GBit we're looking into 3x Mikrotik CRS326-24S+2Q+RM (which are connected for high-availability via 40 GBit) Especially for the "frontend" switches i'm looking for alternatives. Currently we use Huawei C6810-32T16A4Q-LI models with 2x33 LACP connections connected via 10 GBit/s RJ45. But those had ports blocking after a number of errors which resulted in some trouble. We'd like to avoid IOS and clones in general and would prefer a decent web interface. Any comments/recommendations? Best regards, Kai

two ways of adding OSDs? LVN vs ceph orch daemon add

Hi, I am learning about Ceph, and I found this two ways of adding OSDs: https://docs.ceph.com/en/quincy/install/manual-deployment/#short-form <https://docs.ceph.com/en/quincy/install/manual-deployment/#short-form> (via LVM) AND https://docs.ceph.com/en/quincy/cephadm/services/osd/#creating-new-osds <https://docs.ceph.com/en/quincy/cephadm/services/osd/#creating-new-osds> (ceph orch daemon add osd *<host>*:*<device-path>*) Are these two ways equivalents? Thanks, Giuliano,
