Fedora Linux ships, among many, a very useful utility - diskcheck. This RPM installs only two files:

• /etc/diskcheck.conf - small and asimple configuration file for the script
• /etc/cron.hourly/diskcheck - the script itself

diskchek periodically (hourly, by default) checks free space on all partitions and sends a notification email to the administrator (root) reporting any partitions with less than 10% of free disk space. If all paritions have enough disk space it will just keep silent. Which partitions to check/skip, how much free disk space to consider as a warning point, and where to send the email - all of these can be easily tuned via the configuration file.

This tool, while being extremely small, provides a great service - proactive notification. Thing like this can solve lots and lots of headaches while troubleshooting strange behaviours.
