[PVE-User] PVE 1.9 + DRBD + GFS2 backup issue

Hi all,

We have some problems with backups with VMs with disks in a DRBD
"shared" storage.

Shared storage is over DRBD and GFS2, raw files.

Dynamic VM migration in the proxmox cluster works OK.

Backup of those VMs fails. Other backups with non-shared non-GFS2
filesystem work ok.

Error in syslog:

14:48:22 camelot vzdump[8070]: INFO: Starting Backup of VM 110 (qemu)
14:48:24 camelot gfs_controld[9755]: different fs
dev /dev/mapper/netraid1-vm--images with same name
14:48:24 camelot vzdump[8070]: ERROR: Backup of VM 110 failed - command
'mount -t gfs2  /dev/netraid1/vzsnap-camelot-0 /mnt/vzsnap0' failed with
exit code 1

Seems GFS is refusing to mount the snapshot due to having the same
"name" as the original partition.

Is this a known issue? Any work around?

Thanks a lot
Eneko
