So the problem is that swap doesn't get unconfigured, and thus raid0 never
gets shutdown cleanly. Some options are:
1) move the swap to it's own RAID set. It still won't get shutdown properly,
but will take less time to rebuild, and you won't have critical filesystems
on a non-redundant RAID set after a shutdown.
2) Put a line like:
# KEYWORD: shutdown
in /etc/rc.d/swap1 . That way when you do a shutdown, the system will
(hopefully) be able to unconfigure the swap, which should allow the RAID set
to unconfigure cleanly. (Hmm.. there might be something else needed here,
but it's been a while since I last thought about this problem..)
