Trying to move a VM from one cluster to another using an intermediary NFS share.

VM is pretty standard with LVM disks.

Debug output:

Running the command manually:

# ls -l /dev/vg01/vm-109-disk-0
lrwxrwxrwx 1 root root 8 Dec  5 09:19 /dev/vg01/vm-109-disk-0 -> ../dm-22

I had turned the VM off, but then pve deactivates the lvm disks so i activated them manually for it to be able to check the size..

Not sure whats going on, i searched bugs and i got a hit on one that seemed like the same but was flagged for not fixing.
Seems like it should support regular LVM disks tho?
