To move MySQL data and binlog storage to the new volume, continue with these steps:

Make mysql user the owner of /data:
sudo mkdir -p /data/mysql/binlogs
sudo chown -R mysql:mysql /data/mysql

Stop MySQL:
sudo /etc/init.d/mysql stop

Copy the existing data folder (located in /var/lib/mysql by default) into /data:
sudo cp -p -R /var/lib/mysql /data/
sudo cp -p -R /var/log/mysql/mysql-bin.* /data/mysql/binlogs/

Edit the MySQL configuration file and:

1. change the value of datadir (which should be /var/lib/mysql) to the new data folder (/data/mysql).
2. change the value of log_bin (which should be /var/log/mysql/mysql-bin.log) to the same file in the new log folder (/data/mysql/binlogs/mysql-bin.log)
   sudo nano /etc/mysql/my.cnf

Reset AppArmor (Ubuntu Server only?):
sudo nano /etc/apparmor.d/usr.sbin.mysqld
Look for lines beginning with /var/lib/mysql or /var/log/mysql. Change them to their appropriate new locations (/data/mysql and /data/mysql/binlogs, respectively) and save the file.

Restart AppArmor profiles:
sudo service apparmor reload

Restart MySQL:
sudo service mysql start
