Hi,
My ceph cluster has a inconsistent pg. I tried to deep scrub pg and repair pg but not fix problems.
I found that the object that made pg inconsistent depends on snapshot (snap id is 2ccac = 183468) of a image, I deleted this snapshot, then query inconsistent pg and it showed empty, but my ceph cluster still show error inconsistent pg. It's strange that the mismatch object depends on the deleted snapshot still exist on disk.
After deleting the snapshot has the mismatch object, I re-tried to deep scrub and repair pg but it doesn't help to fix.
Information of commands as below. I don't know how to clear this status of inconsistent. Please help me to fix this bug.
