That's pretty ugly, and not an option for me. But I had this exact
same problem, it seems that there are some assumptions about the
disk label in the raid code. Tsk-tsk. Everything would run fine
after setting up the raid as long as I didn't reboot ~:^) Then the
label on the second drive would be toast. SS20, 2.2.x kernel.
