You observe some file systems are out of disk space.


It is never good to run out of disk space. It is particularly bad when you run out of space on /, /tmp or /home.

If you run out of space on a data volume, a volume other than the system disk, just delete files until you free up enough space to continue. You might consider installing more disk space with Linux Volume Management and move your data volumes under LVM control. This will allow you to add disk space easily as the need arises.

Running out of space on /tmp or /home may cause applications to hang, core dump or not start at all. This is because /tmp and /home are popular places to write temporary files and data needed for normal operation. Delete files until you free up enough disk space to continue running normally. Consider switching to LVM in case you need to add disk space in the future.

Running out of space on root "/" can cause serious service interruption. If the server is hung or nonoperational, you need to boot into rescue mode from CD1 of the installation media, mount the root partition manually, free up some disk space and reboot.

Configure the server to automatically clean up old files in temporary directories, such as /tmp and /var/tmp. It is not intended for static files to remain in these directories. You can enable cron to clean them up automatically. For example, if you wanted to delete all files in /tmp and /var/tmp that have not been accessed for 30 days, make the following changes to /etc/sysconfig/cron.

Change from this:


to this:


Save and exit. The /tmp and /var/tmp directories will now be checked daily for old files that have not been accessed. If you have additional directories that you want monitored, you can add them to the LONG_TMP_DIRS_TO_CLEAR list.

Additional Information

Useful commands to resolve low disk-space issues:

Use the "find" command:
Example:  To identify large files that may no longer be needed on /  (root ) use:  "find / -type f -size +1G" (as root user)  to identify files 1G or larger.  Delete them if possible.  If not sure...back them up somewhere else first.  Continue with cleanup by modifying  the last parameter to identify smaller files that can be removed.  i.e.:  "find / -type f -size +500M"
