Hi Igor, Thank you for the detailed analysis. That makes me hopeful we can get the cluster back on track. No pools have been removed, but yes, due to the initial crash of multiple OSDs and the subsequent issues with individual OSDs we’ve had substantial PG remappings happening constantly. I will look up the referenced thread(s) and try the offline DB compaction. It would be amazing if that does the trick. Will keep you posted, here.

Did you initiate some large pool removal recently? Or may be data rebalancing triggered PG migration (and hence source PG removal) for you? Highly likely you're facing a well known issue with RocksDB/BlueFS performance issues caused by massive data removal. So your OSDs are just processing I/O very slowly which triggers suicide timeout. We've had multiple threads on the issue in this mailing list - the latest one is at https://lists.ceph.io/hyperkitty/list/ceph-users@xxxxxxx/thread/YBHNOSWW72ZVQ6PD5NABEEYRDMX7OZTT/ For now the good enough workaround is manual offline DB compaction for all the OSDs (this might have temporary effect though as the removal proceeds). Additionally there are users' reports that recent default value's modification for bluefs_buffered_io setting has negative impact (or just worsen existing issue with massive removal) as well. So you might want to switch it back to true. As for OSD.10 - can't say for sure as I haven't seen its' logs but I think it's experiencing the same issue which might eventually lead it into unresponsive state as well. Just grep its log for "heartbeat_map is_healthy 'OSD::osd_op_tp thread" strings.

out of memory > > > > Hi, > > > > We recently upgraded a cluster from 15.2.1 to 15.2.5. About two days later, one of the server ran out of memory for unknown reasons (normally the machine uses about 60 out of 128 GB). Since then, some OSDs on that machine get caught in an endless restart loop. Logs will just mention system seeing the daemon fail and then restarting it. Since the out of memory incident, we’ve have 3 OSDs fail this way at separate times. We resorted to wiping the affected OSD and re-adding it to the cluster, but it seems as soon as all PGs have moved to the OSD, the next one fails. > > > > This is also keeping us from re-deploying RGW, which was affected by the same out of memory incident, since cephadm runs a check and won’t deploy the service unless the cluster is in HEALTH_OK status. > > > > Any help would be greatly appreciated. > > > > Thanks, > > Stefan > > > > _______________________________________________ > > ceph-users mailing list -- ceph-users@xxxxxxx > > To unsubscribe send an email to ceph-users-leave@xxxxxxx > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx > _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
