[linux-lvm] LVM snapshot?

I have a machine that is running EL5 with xen. One of the DOMU's has an LV
from DOM0 mounted on it to allow access to the data. Is it safe to do 
a snapshot of the LV from DOM0 while it is still mounted rw on the DOMU?

What I would like to do is snapshot the LV, fsck the snapshot and if it comes
up clean, continue on. If it shows errors, then I will schedule downtime
for a real fsck.

Does this sound safe or am I going to get into trouble if I do that?
