It's probably because you have swap space in use on the raid set. Either be sure to do a 'swapctl -U' or similar before 'reboot' or just use 'shutdown', which will execute /etc/rc.shutdown which will "do the right thing" because the "swapoff=YES" rc.conf is now set by default. The latter is the best idea anyway.
There is no swap space on the RAID. And it doesn't make a difference whether I use "shutdown -r" or reboot. The parity is still dirty after the reboot.
