Hello List, 

Im using the following setup:

Two Nodes:
physical harddisks contains a LVM with one VG and 4 LV. Each LV contains a xen based virtual machine.
each LV is connected to the other node by an explicied drbd configuration in drbd.conf /dev/drbd1 to /dev/drbd4. 

Can I make consistend LVM snapshot backups from these four LVs on the secondary side? I've tested it twice and to backup was consistend. Was it luck or does it work? Im not sure.

My Systems:
Kernel: 2.6.32.12-0.7-xen #1 SMP 2010-05-20 11:14:20 +0200 x86_64 x86_64 x86_64 GNU/Linux
drbd: 8.3.7
