Hi,


After updated to version 6.2 when I try to create a Snapshot from a VM is taking forever and not finish.

I see the box Task - VMID - Snaphost, behind Preparing but stay this way.

If I stop the snapshot routine, the VM stay locked and with a Snapshot saying Delete that never disappear, just deleting VM and restore from some backup.

Is someone else having this problem?
 
I have this happening too. CT snapshot backups fail and leave a preparing snapshot that can only be deleted
from CT conf file...

My error is:

Code:
Use of uninitialized value in numeric eq (==) at /usr/share/perl5/PVE/VZDump.pm line 478.

It seems to be happening to all CT's that have a bind mount to the cephfs mount on the host.
Removing the bind mount the issue doesn't appear.

I've had it working until last week, why is this happening now?
