I fake background fsck with a 108G drive. I have it not auto fsck on boot,
(sleep 30; fsck -p /dev/wd1a && mount /export && mount -a ) &
to the end of my /etc/rc.local. That mount is not nessesary for
normal use, of course. /etc/fstab for that mount has a 6th field of
"0". On an unclean boot, it fscks all of the other partitions, then
errors (but continues with regular boot) on /export.
