While trying to do a backup We are getting a strange error:


Code: 
trying to remove stale snapshot '/dev/pve/vzsnap-xanadu-three-0'
INFO: umount: /mnt/vzsnap0: not mounted
ERROR: command 'umount /mnt/vzsnap0' failed: exit code 1

when running mount I see:

Code: 
mount

I am thinking it would/should be safe to remove that snapshot via lvremove - but figured i should ask just in case:
