    run the command du -shc * in /usr and check if you can delete any more unwanted files.

    You should also check /usr/local/apache/htdocs as you may have some unwanted tar files over there.

    use newsyslog or logrotate on those log files to keep them in check and not eat up your drive space ..i just find it weird that they've use /usr for variable files like log files ..should dump it into /var

    The /USR partition

    1. Restart the httpd service. This might free a little space some times.

    2. Check for apache logs like error_log, access_log , suexec_log in /usr/local/apache/logs . These can either be cleared off or if you need the logs then you can take a zipped copy and keep it aside.

    3. Same can be done for the files in cPanel logs (/usr/local/cpanel/logs) as well .

    4. Domlogs – Get into the /usr/local/apache/domlogs/ directory. Run the following command :-

    # ls -al -SR | head -10 —> It will list 10 files in the decreasing order according to their size

    If the domlog file is too large for a domain then it is possible that awstats is not running . Check whether cpanellogd is running on the server using pstree . If not, restart it .
    Else, it is possible that awstats for only that particular domain is not updating. Get into the directory /usr/local/cpanel/base and check if any file as ‘’ exists. If yes , delete that file.

    Now, run /scripts/runweblogs for that user. It will update the awstats and automatically clear the domlogs file thereafter. Do not delete the domlogs file itself.

    5. Remove old and unwanted backups of ‘apache’ that might have been taken long ago. Also, check for any other duplicate folders that can be removed safely.

    6. Remove core files, if any . Normally, some core files (like core.1234) might be present in /usr/local/cpanel/whostmgr/docroot . Check for these and remove them.

    you can try this also
    rm -rf /usr/local/apache/domlogs/*
    service httpd restart

    this will clean your domlogs

    I would recommend you to use logrotate for apache error and access logs so that it wont eat up your disk space in future.
