Hello, No new information. Every two night server OSD 1 freeze with a load > 500. It's every 2 days. Sometime during scrub, sometime during fstrim, sometime during nothing... But this night, this OSD server came not a life after some minutes as before... 8 hours without this server and all its OSD (12/36). This morning, I restart it and now after some hours : HEALTH_WARN 1 pgs degraded; 1 pgs recovering; 1 pgs stuck unclean; recovery 304/46002595 objects degraded (0.001%); recovery 11288/46002595 objects misplaced (0.025%); recovery 3/9779473 unfound (0.000%) pg 50.2dd is stuck unclean for 23531.224308, current state active+recovering+degraded+remapped, last acting [7,28] pg 50.2dd is active+recovering+degraded+remapped, acting [7,28], 3 unfound recovery 304/46002595 objects degraded (0.001%) recovery 11288/46002595 objects misplaced (0.025%) recovery 3/9779473 unfound (0.000%) Pool 50.2dd is a RBD filesystem, XFS with replicat 2x. So what is the best solution ? #ceph pg 50.2dd mark_unfound_lost delete or #ceph pg 50.2dd mark_unfound_lost revert ? What can have more impact to RBD/XFS filesystem ? a xfs_repair required after ? So, I will probably try ceph version 10.2.6 this evening because I really found nothing to fix... Why this freeze ? why only this server OSD freeze and not others ? why every 2 days ? It's crazy. I already checked all : disk, network, soft, all servers are equals. (all issues started the day after upgrade to 10.2.5 from 10.2.3). Thanks for your help.
