The -F option isn't "added" to the array. It's a mdadm run-time
argument that tells it to check the array for errors. The -F option
isn't useful (and may even be illegal) during the array creation phase.
You would typically either create a cron job that does
/sbin/mdadm -F -s -1
periodically, or more typically you would have a system start-up script
that runs
/sbin/mdadm -F -s -f -i /var/run/mdadm.pid -m root
The first version tells mdadm to check the array only once, and output
the status on stdout (which cron then emails to the crontab owner). The
second version tells mdadm to daemonize (-f) using the specified pidfile
(-i /path/to/pidfile) and explicity provides an email address (-m root)
for the resulting status messages.
In both cases, the -s option tells mdadm to look for *all* RAID devices
even if they aren't in the config file.
