restore a vm : dos signature detected on /dev/drbdvg0

[whitewater]

Hello,
On 2 servers, I reinstalled proxmox on a LSI 2208 card with 3 volumes.
1 volume for Proxmox, the other 2 for DRBD.

I created the volumes DRBDr0 and DRBDr1.
Restoring a backup to DRBDr1 is going well.

The following message appears on DRBDr0.
One or more drive were used.

I tried this:
- Suppression of the volume LVM DRBDr0 of proxmox
- Deleting the volume group group DRBDVG0
- a command drbdadm wipefs drbd0
- a wipefs command drbd0 and wipefs/dev/sdb
- All recreate and ...

Message appear again.

What can I do to restore and wipe the signature,
Or how to delete it.

The backup ends and the VM runs, but I still want to overwrite the signature. I think it's cleaner.
