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? Regards, -- Tom Diehl tdiehl@rogueind.com Spamtrap address mtd123@rogueind.com
