I recently wrote a script to check disk space every week and email me an alert
if there was less than 5G. Would that be an approach for you? Enclosing below
as an example. You'd need to adapt to your own environment.
#!/bin/bash
MAILSPACE=$( df -h | grep "/dev/sdd" | awk '{ print $4 }' | sed 's/G//g' )
if [ "$MAILSPACE" -lt "5" ] ; then
MESSAGE="Alert, only $MAILSPACE Gb of space left on Mail Drive"
df -h > /tmp/diskalert.txt
mutt -s "$MESSAGE" m...@example.com < /tmp/diskalert.txt
else
# Uncomment to debug
MESSAGE="Safe for now: $MAILSPACE Gb of space left on Mail Drive"
#echo $MESSAGE
fi
