If you run a check on a degraded array and the check runs into errors it
can't recover from, I assume that the disk will get kicked off and
you'll have a nonfunctional array instead.

Not something I'd do in your situation.

I'll try to finish my patch ASAP.

It should be possible to convince the code to read from the offline disk
when absolutely necessary, but no guarantee that I'll get that in right
away. (On second thought, this only matters for RAID6.)
