Is there a way to automate the disk failure
notification (eg, to send mail to the sys admin)?
I have this script called from cron every 5 minutes with an entry like
this:
*/5 * * * * checkmd -v
If checkmd fails, cron generates a mail message to the owner of the cron
script.
------------ checkmd -------------
#! /bin/bash
#
# This script checks that the md configuration is the same as that
# read at configuration time. When called with the -i option, it
# reads /proc/mdstat and learns the configuration. If called without
# args, it returns non zero status if the configuration is different
# from the one learned, and prints a message if the -v flag is present.
#
# usage: checkmd.sh [-iv]
init=""
verbose=""
CONF=/etc/md.conf
while getopts "iv" opt; do case $opt in
i)
init=true
;;
v)
verbose=true
;;
*)
cat <<-EOF
usage: $0 [-iv] [fromdev] [todev]
-i means init the file $CONF with the current md configuration
-v means display a message in case of configuration mismatch
EOF
exit 1
;;
esac; done
if [ ! -r $CONF -o "$init" = true ]; then
cat /proc/mdstat > $CONF
chmod 444 $CONF
echo "Current configuration saved in $CONF:" >&2
cat $CONF >&2
else
cat /proc/mdstat | cmp $CONF >/dev/null
if [ $? != 0 ]; then
if [ $verbose ]; then
echo >&2
echo "ALARM! md configuration problem" >&2
echo >&2
echo "Current configuration is:" >&2
cat /proc/mdstat >&2
echo >&2
echo "should be:" >&2
cat $CONF >&2
fi
exit 1
fi
fi
