The blob is below, just stick it in your bashrc. My idea was that
everytime I spawn a shell (which is a lot!), mdstat gets checked.
What issues are you having with --monitor? It should be pretty
automatic if you let it scan. I just run something like this:
/sbin/mdadm -F -s -f -y
This stats mdadm in --monitor mode, scans for devices, daemonizes, and
records its results in syslog.
Here's what runs in my bashrc:
# Scream and cry a lot if the RAID looks weird!
if /bin/grep _ /proc/mdstat; then
for ((scream = 0; scream < 5; scream ++)); do
echo -e "POSSIBLE PROBLEM WITH RAID"
sleep 0.1
done
cat /proc/mdstat
fi
