As they are LV's, you may try to make a snapshot and then mount it with
lock_nolock - faster and won't interfere with other services. If you are
not mounting it on dedicated backup node where the fs is not mounted, you
may need to change the UUID and lock table to be able to mount the snapshot
on the same machine.
