Database error

Your /var partition is 100% full and because of that MySQL service is done on the server. If you have free space on your another partition (/home) then you can move your MySQL directory to your /home partition

1. Take a full backup of your all database.

Code:

mysqldump --all-databases | gzip > /home/alldatabases.sql.gz

2. Disable MySQL service through WHM > Service Manager for MySQL and save the area, So that monitor service will not start MySQL service while moving MySQL directory to other partition

3. Stop MySQL service

Code:

/etc/init.d/mysql stop

4. Move your MySQL directory to /home and with following command.

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

5. Enable MySQL service through WHM > Service Manager
