Hi Sam, I saw that ceph 0.94.3 is out and it contains a resolution to the issue below (http://tracker.ceph.com/issues/12577). I installed it on our cluster, but unfortunately it didn't resolve the issue. Same as before, I have a couple of inconsistent pg's, and run ceph pg repair on them - the OSD says: 2015-09-08 11:21:53.930324 7f49c17ea700 0 log_channel(cluster) log [INF] : 2.439 repair starts 2015-09-08 11:27:57.708394 7f49c17ea700 -1 log_channel(cluster) log [ERR] : repair 2.439 b029e439/10000022d93.00000f0c/head//2 on disk data digest 0xb3d78a6e != 0xa3944ad0 2015-09-08 11:28:32.359938 7f49c17ea700 -1 log_channel(cluster) log [ERR] : 2.439 repair 1 errors, 0 fixed 2015-09-08 11:28:32.364506 7f49c17ea700 0 log_channel(cluster) log [INF] : 2.439 deep-scrub starts 2015-09-08 11:29:18.650876 7f49c17ea700 -1 log_channel(cluster) log [ERR] : deep-scrub 2.439 b029e439/10000022d93.00000f0c/head//2 on disk data digest 0xb3d78a6e != 0xa3944ad0 2015-09-08 11:29:23.136109 7f49c17ea700 -1 log_channel(cluster) log [ERR] : 2.439 deep-scrub 1 errors $ ceph tell osd.* version | grep version | sort | uniq -c 94 "version": "ceph version 0.94.3 (95cefea9fd9ab740263bf8bb4796fd864d9afe2b)" Could you have another look?
