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" me at example.com < /tmp/diskalert.txt 
else
	# Uncomment to debug 
	MESSAGE="Safe for now: $MAILSPACE Gb of space left on Mail Drive"
	#echo $MESSAGE
