Re: [PVE-User] Cannot delete snapshot from aborted snapshot creation process

[Frank Thommen <f.thommen@dkfz-heidelberg.de>]

Thanks for the hint, but I am still at a loss here. I haven't 
(knowingly) configured any pools (*). The VM has two virtual disks, 
listed as

   Hard Disk (scsi0): ceph-rbd:vm-118-disk-0
   Hard Disk (scsi1): ceph-rbd:vm-118-disk-1

in the dashboard (Hardware tab). But with a similar `rbd` command I get 
an error:

$ rbd snap ls ceph-rbd/vm-118-disk-0
rbd: error opening pool 'ceph-rbd': (2) No such file or directory
$ rbd snap ls ceph-rbd/vm-118-disk-1
rbd: error opening pool 'ceph-rbd': (2) No such file or directory
$

I could not find an `rbd` subcommand to list all available pools.


(*) well, there is one resource pool "mypool" which I have created when 
playing around a long time ago, but there are no members in that pool 
(see attached screenshot)


Any hint on how to proceed from here?

Frank

In the meantime I found `ceph osd lspools`, which lists

1 pve-pool1
2 cephfs_data
3 cephfs_metadata
4 device_health_metrics

(shouldn't one be able to see that somewhere in the PVE UI?)

and there doesn't seem to be any snapshots there:

$ rbd snap ls pve-pool1/vm-118-disk-1
$ rbd snap ls pve-pool1/vm-118-disk-0
$

I have deleted the snapshot from /etc/pve/qemu-server/118.conf and now 
it's also gone from the UI.

Thanks a lot, Frank
