If you have a /var partition, and if that partition is too small it may fill up quickly. Â If you want to move the data which is stored in "/var" to another partition, run the following:
cd /var
du | sort -n
One common culprit is mysql (/var/lib/mysql on Redhat). Â To move that path to another partition, run the following:
cd /home
mkdir mysql
chown mysql:mysql mysql
cd mysql
/sbin/service mysqld stop
cp -Rp /var/lib/mysql/* .
cd /var/lib
mv mysql mysql_old
ln -s /home/mysql ./mysql
/sbin/service mysqld start
#once satisfied that mysqld is running and functioning correctly, remove the old data:
rm -rf mysql_old
