Ditto, I had a bad optic on 48x10 switch. The only way I detected it was my prometheus tcp fail retrans count. Looking back over the previous 4 weeks, I could seen it increment in small bursts, but Ceph was able to handle it.... and then it went crazy and a bunch of OSD’s just dropped out.

Thanks! Here it is: [root@gnosis ~]# ceph osd dump | grep require require_min_compat_client jewel require_osd_release mimic It looks like we had an extremely aggressive job running on our cluster, completely flooding everything with small I/O. I think the cluster built up a huge backlog and is/was really busy trying to serve the IO. It lost beacons/heartbeats in the process or theygot too old.

Hi Dan, looking at an older thread, I found that "OSDs do not send beacons if they are not active". Is there any way to activate an OSD manually? Or check which ones are inactive? Also, I looked at this here: [root@gnosis ~]# ceph mon feature ls all features supported: [kraken,luminous,mimic,osdmap-prune] persistent: [kraken,luminous,mimic,osdmap-prune] on current monmap (epoch 3) persistent: [kraken,luminous,mimic,osdmap-prune] required: [kraken,luminous,mimic,osdmap-prune] Our fs-clients report jewel as their release. Should I do something about that? Thanks! ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14 ________________________________________ From: Dan van der Ster &lt;dan(a)vanderster.com&gt; Sent: 05 May 2020 17:35:33 To: Frank Schilder Cc: ceph-users Subject: Re: [ceph-users] Ceph meltdown, need help OK those requires look correct. While the pgs are inactive there will be no client IO, so there's nothing to pause at this point. In general, I would evict those misbehaving clients with ceph tell mds.* client evict id=<id> For now, keep nodown and noout, let all the PGs get active again. You might need to mark some in, if they don't automatically come back in. Let the PGs recover, then once the MDSs report no slow ops you can consider taking the cephfs offline while the PGs heal fully. If the beacon messages continue, you need to keep investigating why they aren't sent. (also as a workaround you can set a much higher timeout). -- dan On Tue, May 5, 2020 at 5:30 PM Frank Schilder &lt;frans(a)dtu.dk&gt; wrote: > > Thanks!

Dear all, the command ceph config set mon.ceph-01 mon_osd_report_timeout 3600 saved the day. Within a few seconds, the cluster became: ============================== [root@gnosis ~]# ceph status cluster: id: health: HEALTH_WARN 2 slow ops, oldest one blocked for 10884 sec, daemons [mon.ceph-02,mon.ceph-03] have slow ops. services: mon: 3 daemons, quorum ceph-01,ceph-02,ceph-03 mgr: ceph-02(active), standbys: ceph-03, ceph-01 mds: con-fs2-1/1/1 up {0=ceph-08=up:active}, 1 up:standby-replay osd: 288 osds: 268 up, 268 in data: pools: 10 pools, 2545 pgs objects: 71.52 M objects, 170 TiB usage: 219 TiB used, 1.6 PiB / 1.8 PiB avail pgs: 2539 active+clean 6 active+clean+scrubbing+deep io: client: 26 MiB/s rd, 75 MiB/s wr, 601 op/s rd, 907 op/s wr ============================== I will wait for the slow mon ops to be flushed out (they are dispatched already) or restart the mons tomorrow. Now this event raises a number of questions and I will ask them in a separate thread. Our hypothesis is, that a very aggressive gob pushed the cluster to the limit. At some point an OSD lost beacons and got marked out. This caused peering to happen, adding to the already unbearable load. Shortly after, 5 more OSDs went down, adding even more to the problem. This looks very much like an avalance effect with heartbeat losses that was addressed in an earlier version of ceph. Are we looking at a regression here? Are beacons sent out of band or are they in the same queue as client OPs? To answer some of the recommendations and questions: - network seems fine, but I will look at the switch counters. - in our situation, recovery_sleep did not help although it slowed recovery down. Thanks for all your quick help!

You can force an individual osd to do a soft restart with "ceph osd down <osdid>" -- this will cause it to restart and recontact mons and osd peers. If that doesn't work, restart the process. Do this with a few at first just to make sure it helps, not hurts. You can also adjust "mon_osd_report_timeout" (which defaults to 900s) -- that's the timeout that is marking your osds down. -- dan On Tue, May 5, 2020 at 5:40 PM Frank Schilder &lt;frans(a)dtu.dk&gt; wrote: > > Hi Dan, > > looking at an older thread, I found that "OSDs do not send beacons if they are not active".

Dear Marc, This e-mail is two-part. First part is about the problem of a single client being able to crash a ceph cluster. Yes, I think this applies to many, if not any cluster. Second part is about your question about the time-out value. Part 1: Yes, I think there is a serious problem with certain client I/O that can take a complete cluster down. My oldest report of this is "ceph fs crashes on simple fio test" (https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/4L543LKHB5W…), which gave me: osd op queue = wpq osd op queue cut off = high <-- This was set to "low" The cut-off value was low by default and this seems wrong in any case. It was proposed to make "high" the default, but this did not make it into the code. The default is still "low" (mimic 13.2.8). Setting cut-off to "high" seems to have helped a little bit, but doesn't address the underlying problem. In addition, it seems to be retained in the beacon send mechanism (see part 2 below). If I understood correctly, all ceph deamons use a single event queue (OPs queue) for all communication, meaning that client I/O and cluster health communication like heartbeats or becon sends all end up in a single queue. As a consequence, a client filling up these queues fast enough is able to timeout heartbeats and take a cluster down in an avalanche process just by filling up OP queues. Firstly, the client starts stressing the cluster with overloading every queue. At some point, the first OSD gets marked down, which triggers remapping and recovery, adding load on top of an already overloaded system. More OSDs go down, more remapping, more peering, more clients trying to reconnect, ..., a total meltdown. In my opinion, client I/O and all cluster communication should be handled by two different queues, where cluster communication always has precedence over client I/O. Cluster health must be ensured at all cost, even if client I/O might be a bit slower in certain situations. We are trying to find out what workload exactly killed our cluster. It is most likely something like the fio test I posted in my earlier thread, but amplified by multi-node concurrent access this time. We saw an enourmous amount of small packets sent from a few clients. To give an idea of scale, the pool backing the file system has 10 servers, 150 spinning disks for an 8+2 EC data pool, and 10 SSDs for the meta-data and the replicated default data pool. The SSDs have very high IO performance, for my taste they are too fast for the spindles in the EC pool. The MDS is able to acknowledge operations multiple times faster than operations can get transferred to the HDDs. Our suspect for the critical workload is a compute job that run on just 8 servers from an HPC cluster (application is probably wrf). The suspected workload is small size random I/O with lots of explicit sunc() calls. I plan to create a separate thread "Cluster outage due to client IO" for this discussion. Part 2: As far as I understand from the documentation (https://docs.ceph.com/docs/mimic/rados/configuration/mon-osd-interaction/#o…), the parameter "mon_osd_report_timeout" sets a time-out for how long a monitor will wait for a status report from an OSD . This health mechanism seems to be independent of heartbeats. Unfortunately, the documentation is not in sync with the implementation, parameters that are described do not exist ("osd_mon_report_interval_max") and parameters that exist are not described ("osd_beacon_report_interval"). I guess "osd_beacon_report_interval" defines the minimum frequency of beacon reports sent to the mons. Default is 5min (not 2min as documented for "osd_mon_report_interval_max"). The default for "mon_osd_report_timeout" is 15min. So it seems quite possible that a busy OSD misses to send its beacons in time when client I/O has the same (or even higher??) priority. Since heartbeats seem to have worked fine even though they are sent with much higher frequency, I decided not to rely on the beacon send too much. When an OSD goes down, its peers will react fast. Hence, I might increase "mon_osd_report_timeout" even further, it seems secondary and more a source of pain than help. In addition, the documented functionality does not work. According to the documentation, a mon marks an OSD down when it does not receive its beacons for the time-out period. I had a few OSDs shut down on purpose after draining, but they were never marked down. So, something does either not work properly, or the documentation is wrong here as well. Note that the OSDs in question were in their own sub-tree and all shut down at the same time. In the past (mimic 13.2.2), such OSDs were marked down after some time. This time (mimic 13.2.8), they stayed up and in for 4 to 5 days until I restarted them in a different crush location. This was a long one. Hope you made it all the way down.

Is this related to the suggested ntp / time sync? From the name I assume that now your monitor just waits longer before it reports the osd as 'unreachable'(?) So your osd has more time to 'announce' itself. And I am a little worried when I read that a job, can bring down your cluster. Is this possible with any cluster? -----Original Message----- Cc: ceph-users Subject: [ceph-users] Re: Ceph meltdown, need help Dear all, the command ceph config set mon.ceph-01 mon_osd_report_timeout 3600 saved the day. Within a few seconds, the cluster became: ============================== [root@gnosis ~]# ceph status cluster: id: health: HEALTH_WARN 2 slow ops, oldest one blocked for 10884 sec, daemons [mon.ceph-02,mon.ceph-03] have slow ops. services: mon: 3 daemons, quorum ceph-01,ceph-02,ceph-03 mgr: ceph-02(active), standbys: ceph-03, ceph-01 mds: con-fs2-1/1/1 up {0=ceph-08=up:active}, 1 up:standby-replay osd: 288 osds: 268 up, 268 in data: pools: 10 pools, 2545 pgs objects: 71.52 M objects, 170 TiB usage: 219 TiB used, 1.6 PiB / 1.8 PiB avail pgs: 2539 active+clean 6 active+clean+scrubbing+deep io: client: 26 MiB/s rd, 75 MiB/s wr, 601 op/s rd, 907 op/s wr ============================== I will wait for the slow mon ops to be flushed out (they are dispatched already) or restart the mons tomorrow. Now this event raises a number of questions and I will ask them in a separate thread. Our hypothesis is, that a very aggressive gob pushed the cluster to the limit. At some point an OSD lost beacons and got marked out. This caused peering to happen, adding to the already unbearable load. Shortly after, 5 more OSDs went down, adding even more to the problem. This looks very much like an avalance effect with heartbeat losses that was addressed in an earlier version of ceph. Are we looking at a regression here? Are beacons sent out of band or are they in the same queue as client OPs? To answer some of the recommendations and questions: - network seems fine, but I will look at the switch counters. - in our situation, recovery_sleep did not help although it slowed recovery down. Thanks for all your quick help!

You can force an individual osd to do a soft restart with "ceph osd down <osdid>" -- this will cause it to restart and recontact mons and osd peers. If that doesn't work, restart the process. Do this with a few at first just to make sure it helps, not hurts. You can also adjust "mon_osd_report_timeout" (which defaults to 900s) -- that's the timeout that is marking your osds down. -- dan On Tue, May 5, 2020 at 5:40 PM Frank Schilder &lt;frans(a)dtu.dk&gt; wrote: they are not active".

Dear Marc, thank you for your endurance. I had another slightly different "meltdown", this time throwing the MGRs out and I adjusted yet another beacon grace time. Fortunately, after your communication, I didn't need to look very long. To harden our cluster a bit further, I would like to adjust a number of advanced parameters I found after your hints. I would be most grateful if you (or anyone else receiving this) still have enough endurance left and could check whether what I want to do makes sense and if the choices I suggest will achieve what I want. Parameters with section of documentation, default in "{}", current value plain, new value prefixed with "*". There is an error in the documentation, please let me know if my interpretation is correct. MON-MGR beacon adjustments -------------------------- https://docs.ceph.com/docs/mimic/mgr/administrator/ mon mgr beacon grace {30} 300 This helped mitigating the second type of meltdown. I took 2 times the longest observed "mon slow op" time to be safe (MGR beacon handling was slow op). Our MGRs are no longer thrown out in case of the incident (see very end for more info). MON-OSD communication adjustments ------------------------ https://docs.ceph.com/docs/mimic/rados/configuration/mon-osd-interaction/ osd beacon report interval {300} 300 mon osd report timeout {900} 3600 mon osd min down reporters {2} *3 mon osd reporter subtree level {host} *datacenter mon osd down out subtree limit {rack} *host "mon osd report timeout" is increased after your recommendation. It is set to a really high value as I don't see this critical for fail-over (the default time-out suggests that this is merely for clean-up and not essential for healthy I/O). OSDs are no longer thrown out in case of the incident (see very end for more info). "down reporter options": We have 3 sites (sub-clusters) under region in our crush map (see below). Each of these regions can be considered "equally laggy" as described in the documentation. I do not want a laggy site to mark down OSDs from another (healthy) site without a single OSD of the other site confirming an issue. I would like to require that at least 1 OSD from each site needs to report an OSD down before something happens. Does "3" and "datacenter" achieve what I want? Is this a reasonable choice with our crush map? Note that, as a speciality, DC2 currently links to some hosts of DC3 (to change in the future). "mon osd down out subtree limit": A host in our cluster is currently the atomic unit which, if it goes down, should not trigger rebalancing on the cluster as this indicates a server and not a disk fail. In addition, if I understand it correctly, this will also act as an automatic "noout" on host level if, for example, a host gets rebooted. mon osd laggy * I saw tuning parameters for laggy OSDs. However, our incidents happen very sporadically and are extremely radical. I do not think that any reasonable estimator will be able to handle that. So my working hypothesis is, that I should not touch these. Error in documentation -------------------- https://docs.ceph.com/docs/mimic/rados/configuration/mon-osd-interaction/#o… osd_mon_report_interval_max {Error ENOENT:} osd beacon report interval The documentation mentions "osd mon report interval max", which doesn't exist. However "osd beacon report interval" exists but is not mentioned. I assume the second replaced the first? Condensed crush tree -------------------- region R1 datacenter DC1 room DC1-R1 host ceph-08 host ceph-09 host ceph-10 host ceph-11 host ceph-12 host ceph-13 host ceph-14 host ceph-15 host ceph-16 host ceph-17 datacenter DC2 host ceph-04 host ceph-05 host ceph-06 host ceph-07 host ceph-18 host ceph-19 host ceph-20 datacenter DC3 room DC3-R1 host ceph-04 host ceph-05 host ceph-06 host ceph-07 host ceph-18 host ceph-19 host ceph-20 host ceph-21 host ceph-22 Additional info about our meltdowns: With "mon mgr beacon grace" and "mon osd report timeout" set to really high values, I finally managed to isolate a signal in our recordings that is connected with these strange incidents. It looks like a package storm is hitting exactly two MON+MGR nodes, leading to beacon time-outs with default settings. I will not continue this here, but rather prepare another thread "Cluster outage due to client IO" after checking network hardware. It looks as if two MON+MGR nodes are desperately trying to talk to each other but fail. And this after only 1.5 years of relationship :) Thanks for making it a second time!
