Subject: [PATCH] MNAIO: Clean up existing data when switching backing store
When switching from LVM to a file backing store, the existing pool
cannot be undefined until any existing VM's and LV's are removed.
This ensures that if this is the case, it will be cleaned up so
that the switch is effortless.
