Hi,
If you run "rbd snap ls --all", you should see a snapshot in
the "trash" namespace.
I just tried the command "rbd snap ls --all" on a lab cluster
(nautilus) and get this error:
ceph-2:~ # rbd snap ls --all
rbd: image name was not specified
Are there any requirements I haven't noticed? This lab cluster was
upgraded from Mimic a couple of weeks ago.
ceph-2:~ # ceph version
ceph version 14.1.0-559-gf1a72cff25
(f1a72cff2522833d16ff057ed43eeaddfc17ea8a) nautilus (dev)
Regards,
Eugen

Hi,
on one of my clusters, I'm getting error message which is getting
me a bit nervous.. while listing contents of a pool I'm getting
error for one of images:

is this something to worry about? What is snap-trash feature?
wasn't able to google
much about it..
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
