Ah sadly those logs don't look like they have enough debugging to be of much use.
But from what I'm seeing here, I don't think this state should actually hurt anything. It ought to go away the next time you delete a snapshot (maybe only if it has data in those PGs? not sure) and otherwise be ignorable. I've created a ticket at http://tracker.ceph.com/issues/24876

And it doesn't get cleared by scrubbing; only when it starts snaptrimming again.If you have any OSD logs of when this happened, that would be helpful.And, uh, Sage? Do you know what was supposed to happen here? It's a bit odd as a PG state.-Greg_______________________________________________I tried to restart OSD, then I run deep-scrub and repair, but it didn't solve the problem.In the documentation the page "Repairing PG inconsistencies" is empty - http://docs.ceph.com/docs/mimic/rados/operations/pg-repair/,so I don't know, what else can I do?Cluster info;vaersion 12.2.525 OSD nodes12 OSD per node. The most of them still have filestore as storage backend.
