Hmm... it sure should... At least, I'm sure that functionality was
there in 2.0... (it's certainly there for 3.0)

If the set gets shutdown properly, then the spare disk should show up
in the right spot when the system comes back up... I know there were
a few minor bugs related to that, but they should have been fixed for
2.0 (IIRC). You may also be able to cheat your way around those bugs by
doing another "raidctl -I" on the set before rebooting -- that should at
least force the labels to be close enough that after a reboot, the
used_spare should show up in the regular component spot (though depending
on the bug, it may be marked as failed or something).
