The log file is in use, most likely by the syslog service (you can easily verify it using the lsof command). This means that the application creates a hard link and uses it to populate the log file: if you remove the file, the hard link is still there and keeps the disk space usage. You can restart the syslogd service using either
Code:
/etc/init.d/syslogd restart
or
Code:
kill -1 `cat /var/run/syslogd.pid`
In this way the service frees the log file, the hard link is destroyed and the space is available again.

Anyway I would investigate why the error-log file is used so heavily. Maybe you can limit the logging of the httpd service acting on the related iptables rules. Just an idea.

zero log file

If I may add to the above: removing a log file while software is running is nearly ALWAYS a bad idea.
Better to 'zero' the log file by usine a command line such as " > logfile ".
while less prone to causing problems, this also is not the BEST solution. Best is to drop services, clean up logs and temp files, then restart services. Best is not always an option if a service outage would impact a production process, so I have used this 'second best' solution of returned a log to 'zero' using redirection often.

Are your logs rotated?
Then you can run a script to delete the rotated logs.
You can set logrotate to rotate, when a certain size is reached

Kind regards

The /var partition may be separate from the / partition, and there is no "simply" with lvextend. Running lvextend on a partition also means you have to run resize2fs, which you can't do on a mounted volume. If you do it, you'll wind up with a non-readable disk after you reboot. You have to be booted from a rescue CD/DVD, into single-user before doing those things.

If you're going to try to answer a question, please provide the OP with complete details, so they don't wind up with a broken system.
