Hello,

Recently when running "rbd ls -l .. " I am seeing list of all the 
existing disks/snapshots but also this error:

rbd: error opening vm-225-state-XXXXXXXX_before_upgrade_03may2022: (2) 
No such file or directory
...
rbd: listing images failed: (2) No such file or directory

I am quite certain that this was a snapshot from vm-225-disk-0 however 
we only now have vm-225-disk-2 in use and -0 and -1 were deleted some 
time ago.

My question is how is the rbd ls command aware of this missing snap from 
a missing disk and then how can I clean this up so the error goes away. 
We have Proxmox mostly using this cluster and removing VMs and that in 
particular doesn't like the fact we're exiting non-zero when removing 
Ceph disks.

Thanks in advance.

Luke
