This implies that you are (or were) using transparent image clones and that you deleted a snapshot that had one or more child images attached to it. If you run "rbd snap ls --all", you should see a snapshot in the "trash" namespace. You can also list its child images by running "rbd children --snap-id <id from snap ls> <image-spec>". There definitely is an issue w/ the "rbd ls --long" command in that when it attempts to list all snapshots in the image, it is incorrectly using the snapshot's name instead of it's ID. I've opened a tracker ticket to get the bug fixed [1]. It was fixed in Nautilus but it wasn't flagged for backport to Mimic. > I'm running ceph 13.2.4 on centos 7. > > I'd be gratefull any help > > BR > > nik > > > -- > ------------------------------------- > Ing.
