I figured you were just busy, but wanted to see if anyone else could
guide my debugging before my boss made me give up and do RAID-5 :)
Thanks for the reply.

Yes, same problem. If I create a full array with 6 devices, wait for
it to finish the synchronizing, then fail the first drive, I see the
same corruption. See attached r6test-full.sh to demonstrate.

FWIW, this does occur with an array created with 2 missing drives, as
well.
