[CentOS-virt] LVM Lockout

[Ben M.]

That worked the first time (or second time, I still keep trying to add 
the additional storage). I couldn't it mount until I unplugged the 
second (new) raid1 this time.

It might be connected to how dmraid is loading up. dmraid loads during 
the xen-kernel bootup, right?
