    Hello,

    I am having issues with my server because of storage running out and found that /var is taking almost 14GB. var/log is taking around 3GB and var/lib is taking around 6GB.

    Could someone please help me how to clean it up?

    Thanks in advance.

    Hello,
    First you have to check which exact log file taking space.Also, check which file/directory taking space under /var/lib using the command "du -sch *"

    Please check and update here with file/directory name so that I can assist you.

    Thanks for the update.

    It's seems that your mysql directory is using 5.6GB disk space on your server. You can remove old logs from your /var/log directory or you can move your mysql directory to other partition to make free space on /var partition

    If you want to move your mysql directory to any other partition then you can try with following steps.

    You can symlinking the old /var/lib/mysql to the new location

    Code:
    ln -s /home/var_mysql/mysql /var/lib/mysql
    First make a full mysqldump file
    Code:
    mysqldump --all-databases | gzip > /home/alldatabases.sql.gz
    Uncheck monitor in WHM > Service Manager for Mysql and save the area and stop mysql service.

    Make the directory for MySQL in /home, move it and symlink it:

    Code:
    mkdir /home/var_mysql
mv /var/lib/mysql /home/var_mysql
chown -R mysql:mysql /home/var_mysql/mysql
ln -s /home/var_mysql/mysql /var/lib/mysql
/etc/init.d/mysql start
    Re-check monitor in WHM > Service Manager for MySQL and save the area

    If anything goes wrong, you have the full mysqldump backup.

    Hello!

    cPanel logs are managed through the cPanel Log Rotation Configuration interface.

    cPanel Log Rotation Configuration - Documentation - cPanel Documentation

    You can also manage the size threshold for those under Tweak Settings.

    Tweak Settings - Stats and Logs - Documentation - cPanel Documentation

    For logs that aren't managed there, you will likely need to clear those out or remove them manually. This is also a good page for a reference on that as well.
