Steps to reproduce:
1. Setup Fuel with multipath device and 3 slave nodes.
2. Create environment with 1 controller, 1 compute and 1 cinder.
3. Provision nodes.

Expected results:
All nodes a provisioned.

Actual results:
Controller node can't boot.

The boot process fails with the following messages:
 Incrementally starting RAID arrays...
 mdadm: CREATE user root not found
 mdadm: CREATE group disk not found
 Incrementally starting RAID arrays...
and slowly repeats the above at this point.
