So this crash means we failed to write all the blocks required to commi=
t
the transaction. The reason is that we're getting failed bios to the
missing device, and that failure isn't properly eaten by the
raid aware endio code.
If you pull the top commit from my for-linus branch, it should all work=
=2E
I know you've got a big FS here, I haven't tested this on raid10 yet,
only raid1. If you want to wait a bit for safety I'll do a raid10 run
too.

The fix looks good to me, and I've tested it on raid10.
