Hi Craig, Yes we have stability problems. The cluster is definitely not suitable for a production environment. I will not describe the details here. I want to get to know ceph and this is possible with the Test-cluster. Some osds are very slow, less than 15 MB / sec writable. Also increases the load on the ceph nodes to over 30 when a osd is removed and a reorganistation of the data is necessary. If the load is very high (over 30) I have seen exactly what you describe. osds go down and out and come back up and in. OK. I'll try the slow osd to remove and then to scrub, deep-scrub the pgs. Many thanks for your help. Regards, Mike ________________________________ Von: Craig Lewis [clewis at centraldesktop.com] Gesendet: Mittwoch, 13.

Sorry about that. Are you having problems with OSD stability? There's a lot of history in the [recovery_state][past_intervals]. That's normal when OSDs go down, and out, and come back up and in. You have a lot of history there. You might even be getting into the point that you have so much failover history, the OSDs can't process it all before they hit the suicide timeout. [recovery_state][probing_osds] lists a lot of OSDs that have recently owned these PGs. If the OSDs are crashing frequently, you need to get that under control before proceeding. Once the OSDs are stable, I think Ceph just needs to scrub and deep-scrub those PGs. Until Ceph clears out the [recovery_state][probing_osds] section in the pg query, it's not going to do anything. ceph osd lost hears you, but doesn't trust you. Ceph won't do anything until it's actually checked those OSDs itself. Scrubbing and Deep scrubbing should convince it. Once that [recovery_state][probing_osds] section is gone, you should see the [recovery_state][past_intervals] section shrink or disappear. I don't have either section in my pg query. Once that happens, your ceph pg repair or ceph pg force_create_pg should finally have some effect. You may or may not need to re-issue those commands.
