# raidcheck perlscript explanation
# releasenote for V0.50b
# last-update: 2004-08-05

short howto:

first install Mail::Sendmail class from CPAN

do the following:

bash$ perl -MCPAN -e shell

cpan> install Mail::Sendmail

---

on debian you can do "apt-get install libmail-sendmail-perl"

-------

after that you're ready to go forward:

cd ~
wget http://ftp2.kapper.net/pub/kapper.net/raidcheck/raidcheck.pl

make it executable:

chmod +x raidcheck.pl

put the file where you'd like, probably somewhere useful for root,
for example (as root or at least privileged user):

mv raidcheck.pl /usr/local/sbin/raidcheck

now preferrably as root (at least privileged enough to write to /var/log)
start this once in order to read and store your current raid-status:

raidcheck -r

probably have yourself a look if your raid is fully operational by:

cat /prod/mdstat

so - you're fine, now you'd like to get notified if something breaks,
at least that's what this script is finally here for :)

do something like (depends on how often you'd like to check):

echo "/usr/local/sbin/raidcheck -c -s sysop@example.com" > /etc/cron.hourly/raid_check
chmod +x /etc/cron.hourly/raid_check

and finally you're done. sysop@example.com will get hourly notices if something has
changed in your raid.
