It is built in to my nagios plugins package at least, and works great.
All right, I didn't see it.
I was thinking of monitoring remote servers; I wrote something very simple.
It checks how many "U" letters there are in /proc/mdstat, and compares
it to $DEVICES number we have.
First, run this one on a remote machine, via cron:
#!/bin/bash
# This script prints the status of RAID device on this machine
# how many RAID devices/partitions do we have here?
DEVICES=8
# no need to change anything below...
RUNNING=$(cat /proc/mdstat | tr -cd "U" | wc -c)
if [ "$DEVICES" == "$RUNNING" ] ; then
echo "RAID status OK" > /tmp/raid-status.txt
else
echo "RAID broken" > /tmp/raid-status.txt
fi
And then poll the results from the nagios server (let's call it
"check_raid" nagios plugin):
#!/bin/bash
# checks state of software RAID
STATUS=$(ssh -l checkuser -i ~nagios/.ssh/checkuser.rsa $1 "cat
/tmp/raid-status.txt")
if [ "$STATUS" == "RAID status OK" ] ; then
echo $STATUS
exit 0
else
echo $STATUS
exit 2
fi
