backup failed - command 'qm set 101 --lock backup' failed with exit code 255

[doknet]

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.

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

 qm unlock 101

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.

Seems the VM is looked bay another "vzdump" already running?

If not, simply unlock it:

qm unlock 101
