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? The fix was merged into master in 6a949e10198a1787f2008b6c537b7060d191d236, after v0.94.3 was released. It will be in v0.94.4. Note that we had a bunch of similar errors on our internal lab cluster and this resolved them. We installed the test build from gitbuilder, available at http://gitbuilder.ceph.com/ceph-rpm-centos7-x86_64-basic/ref/hammer/ (or similar, adjust URL for your distro). sage > > Thanks, > > Andras > > > ________________________________________ > From: Andras Pataki > Sent: Monday, August 3, 2015 4:09 PM > To: Samuel Just > Cc: ceph-users@xxxxxxxxxxxxxx; ceph-devel@xxxxxxxxxxxxxxx > Subject: Re: Inconsistent PGs that ceph pg repair does not fix > > Done: http://tracker.ceph.com/issues/12577 > BTW, I¹m using the latest release 0.94.2 on all machines. > > Andras > > > On 8/3/15, 3:38 PM, "Samuel Just" <sjust@xxxxxxxxxx> wrote: > > >Hrm, that's certainly supposed to work.
