I ended up writing a small cron script to check the status of the
array.  It is located at
http://cvs.pfsense.org/~sullrich/misc/rc_scripts/rc.check_areca if
anyone else is
interested.   I also added a zfs watch script that runs from cron:
http://cvs.pfsense.org/~sullrich/misc/rc_scripts/rc.check_zfs_degraded

YMMV.
