that is, i just need to sync open devices so i can see on server #2 if the device is mounted in server #1.

as you see in one server the device is *marked* as open, in the other is not.

i need just to see open in both server,
if it is marked as open, xen refuse to boot vm with that device open, and i will not care about the filesystem that is contained in lvm.
