Hi, I've been searching and trying things but to no avail yet. This is uncritical because it's a test cluster only, but I'd still like to have a solution in case this somehow will make it into our production clusters. It's an Openstack Victoria Cloud with Ceph backend. If one tries to remove a glance image (openstack image delete {UUID}' which usually has a protected snapshot it will fail to do so, but apparently the snapshot is actually moved to the trash namespace. And since it is protected, I can't remove it: storage01:~ # rbd -p images snap ls 278ffe2b-67a7-40d0-87b7-903f2fc9c3b4 --all SNAPID NAME SIZE PROTECTED TIMESTAMP NAMESPACE 159 1a97db13-307e-4820-8dc2-8549e9ba1ad7 39 MiB Thu Dec 14 08:29:56 2023 trash (snap) storage01:~ # rbd snap rm --snap-id 159 images/278ffe2b-67a7-40d0-87b7-903f2fc9c3b4 rbd: snapshot id 159 is protected from removal. storage01:~ # rbd snap ls images/278ffe2b-67a7-40d0-87b7-903f2fc9c3b4 storage01:~ # This is a small image and only a test environment, but these orphans could potentially fill up lots of space. In a newer openstack version (I tried with Antelope) this doesn't seem to work like that anymore, so that's good. But how would I get rid of that trash snapshot in this cluster? Thanks! Eugen
