+You can modify the cron job to send you an email when any
+filesystem is going to run out of space.  The system is
+very flexible and can work on %usage thresholds, absolute
+amount of free space remaining, inode numbers and so on.
+</p>
 
+<p>
+The basic plan is outlined in
+<a href="http://rwmj.wordpress.com/2010/04/02/tip-find-out-when-filesystems-get-full-with-virt-df-working-version/#content">this blog posting</a>.

+In order to get cron to send you an email, put the code from the above
+posting into a script and set up cron like this:
+</p>
 
+<pre>
+MAILTO=you@example.com
+0 3 * * *    /path/to/script
+</pre>
 
+<p>
+This will send email if the script produces any output
+(ie. when your criteria are met).
