When I've had an unclean shutdown on one of my systems (10x 50gb raid5) it's
always slowed the system down when booting up.  Quite significantly I must
say.  I wait until I can login and change the rebuild max speed to slow it
down while I'm using it.   But that is another thing.

i use an external write-intent bitmap on a raid1 to avoid this... you 
could use internal bitmap but that slows down i/o too much for my tastes.  
i also use an external xfs journal for the same reason.  2 disk raid1 for 
root/journal/bitmap, N disk raid5 for bulk storage.  no spindles in 
common.

I must remember this if I have to rebuild the array.  Although I'm
considering moving to a hardware raid solution when I upgrade my storage.
