Great.  I'll continue testing as I start using it on one of my file
servers.

Another issue:  If I create a 6-disk RAID-6 array ...

... with 2 missing, no resync happens.
... with 1 missing, no resync happens.  (???)
... with 0 missing, resync happens.
... with 2 missing, then add 1, recovery happens.
... with 0 missing, then fail 1, resync continues.

Shouldn't resync happen in the created-with-1-disk-missing case?
