Hi Paul, This is a small test cluster, and the rbd pool is replicated. I am hardly using any clients on the cluster. Furthermore I have been the only one creating the snapshots and I know for sure that I was not trying to delete them. If so I have been doing this on one of the ceph nodes. I have these issues on images with create_timestamp: Tue Jul 18 20:51:40 2017 create_timestamp: Fri Sep 1 13:55:25 2017 create_timestamp: Fri Sep 1 13:59:10 2017 create_timestamp: Wed Jan 3 16:38:57 2018 Updates have been done in February, so theoretically I should not be seeing these than any more?

Should this snapshot be considered lost? And is deleting this snapshot the only way to fix this? -----Original Message----- From: Paul Emmerich [mailto:paul.emmerich@xxxxxxxx] Sent: dinsdag 10 april 2018 20:14 To: Marc Roos Cc: ceph-users Subject: Re: Ceph scrub logs: _scan_snaps no head for $object? Hi, you'll usually see this if there are "orphaned" snapshot objects. One common cause for this are pre-12.2.2 clients trying to delete RBD snapshots with a data pool (i.e., erasure coded pools) They send the snapshot requests to the wrong pool and you end up with lots of problems.
