Alas, this (type of) compute node is designed specifically to use local
storage instead of (shared) network storage. This prevents live migration.
If live migration were possible (and it would include migrating the
disk storage), then this would more or less automatically solve
the problem: on the new node the LV would be a fresh one
and thus nicely mirrored.

Maybe somebody could add support for something like that to OpenStack,
but right now it can't do it.
