Hi I have configured and working properly Proxmox system and drbd, under the guidance of http://pve.proxmox.com/wiki/DRBD
But now I have a problem trying to make some bk snapshot vm running on that system.
Probe both the kernel 2.6.24 to 2.6.32 ; both giving me error, as when the machine is active and when it turned off.
I read the post, and Im do not clear, you need a disk separately to make a snapshot?
How toy make snapshot of vm ?
The problem occurs both when I try from the command line and when I try to do it from scheduled backups from the web interface .-
Thank.

Code:

Sorry now I see the post
http://forum.proxmox.com/threads/3777-SOLVED-Problem-with-backup-qemu-kvm-VID
And change the line of the conf last line
Code:
 qm unlock 101
vm1:~# cat /etc/qemu-server/101.conf
ostype: l26

Code:
rum 
vzdump --dumpdir /var/lib/vz/dump/  --snapshot  101

Code:
ls -l /var/lib/vz/dump 
ls -l /var/lib/vz/dump/

I ask now.
Has any utility or serves some protection in the conf line lock: backup?
Is there any way to create a new machine in the drbd device with backups.?
Someone might suggest the command
From already thank you very much.
