mysql is the name of the partition you created when installing the OS
∏
pf1_server_name and pf2_server_name by the real server names
∏
x.x.x.x and y.y.y.y by the IP addresses dedicated to DRBD on each server (use a dedicated NIC for
this, not the main one with all the IPs)
∏
YOUR_PARTITION_DEVICE is the device to use for the MySQL partition (ie. /dev/sda2)
Then initialize the partition:
[root@pf1 ~]# drbdadm create-md mysql
