Looks similar to a problem I had after a several OSDs crashed while trimming snapshots. In my case, the primary OSD thought the snapshot was gone, but some of the replicas are still there, so scrubbing flags it.
First I purged all snapshots and then ran ceph pg repair on the problematic placement groups. The first time I encountered this, that action was sufficient to repair the problem. The second time however, I ended up having to manually remove the snapshot objects. http://lists.ceph.com/pipermail/ceph-users-ceph.com/2018-June/027431.html Once I had done that, repair the placement group fixed the issue. -Steve On 11/16/2018 04:00 AM, Marc Roos wrote: > > > I am not sure that is going to work, because I have this error quite > some time, from before I added the 4th node.
