Ugh. Why would you want to check every _3 seconds_ for a disk failure?
That's a lot of wasted cycles. Instead of forking a few different programs
like that, how about:
a cronjob that runs every 5 minutes and just diffs mdstat and a copy of a
good mdstat:
*/5 * * * * /usr/bin/diff /mdstat.good /proc/mdstat
Just do "cp /proc/mdstat /mdstat.good", and that's it. You'll get a mail if
there's a difference (including failure), and no mail if they're the same.
You still get mailed every 5 minutes, but you don't use quite so many cycles
and processes to do it. (worst case, you have a 5-10 minute window with a
failed disk. If you're worried about it, change the */5 to * ...) You could
also throw this into a monitor using "mon"
(http://www.kernel.org/software/mon) which you can set to mail you once an
hour/etc.
