This is how to get some more info on what files are eating up your harddrive. The
du -x . | sort -n
command forces the
du
(disk usage) command to limit itself to the /var/log partition. The
sort
command will sort the output of du to display from smallest to largest files. In the example below you can see that the directory /var/log itself usages the most disk space.
[root@nielsvs-bigip:Active:Standalone] ~ cd /var/log
[root@nielsvs-bigip:Active:Standalone] log du -x . | sort -n

You can also sort on the largest files in de /var/log directory itself.
[root@nielsvs-bigip:Active:Standalone] log ls -Slh | head -10

Maybe you can remove some old logfiles or make sure you turn off some debugging to log less.
