Can you try this: 1. Go to the host 2. Stop OSD 595 3. ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-595 --op info --pgid 1.323 What does osd.595 think about that PG? You could even try 'rm-past-intervals' with the object-store tool, but that might be a bit dangerous. Wouldn't do that immediately.
