Public bug reported:
After upgrading to 12.04 from 11.10 my RAID array vanished and refused
to mount.
Entering the command "sudo dmraid -ay -vvv -d -i" shows this towards the
end of the output.

Note that dm-7 and sdc are in fact the same disk, the same goes for dm-6
and sdd. Prior to the 12.04 update dmraid would simply ignrore the sd*
disks.
