[ceph-users] Re: Orphaned CephFS objects

Thanks, Greg. Suggestions for remediation?

The MDS/client created the snapshotted data, but deleting a snapshot is just a metadata update: it tells the monitor “please delete snapshot ID 1234”, and the monitor puts 1234 in the osdmap as a snapshot to be deleted. Then the OSDs do that work asynchronously and outside of cephfs’ supervision. So, that must have happened, and there was this bug in RADOS that meant the snapshot didn’t actually get (fully) trimmed. -Greg
