Expandind Size of Centos P
I have a pc installed with CENTOS 6.3 as a mail server. Postfix with mysql is installed but it is running out of size now. I want to add another hard disk to extend the size of /usr/bin/mysql.
Before doing it I want to backup my mysql database with dum which is not a proble. I need an assisstance on how to add another HD for i believe there are some work to be done not just to plug the HD.
