Relocate mySQL file to XFS partition

Stop the mySQL service:
	service mysqld stop

rsync copies files while retaining permissions and ownership
Copy the mySQL data files to the XFS partition using rsync:
	mkdir /xfspart/mysql
	rsync -avz /var/lib/mysql/ /xfspart/mysql
	chown mysql.mysql /xfspart/mysql

Map mySQL configuration to the new directory:
	nano /etc/my.cnf
	Edit line:
		datadir = /xfspart/mysql

Start the mySQL service:
	service mysqld start

Verify datadir variable has been set in my.cnf:
	mysql -u root -p
	<password>
	>SHOW VARIABLES LIKE 'datadir';
