[ovirt-users] iscsi data domain when engine is down

[Chris Adams]

It's easy enough to verify; just SSH in to the physical machine running
the hosted engine and look.  You can see the qemu command line, follow
the links to the block device, then look at the LVM physical volume and
see that it is a multipath device.
