Problem with HA configuration

I followed this guide to setup my HA server

http://library.linode.com/linux-ha/ip-f … untu-10.04">http://library.linode.com/linux-ha/ip-failover-heartbeat-pacemaker-drbd-mysql-ubuntu-10.04

Everything looks OK until I put ha-1 on standby. It seems mysql would not start on ha-1. Can you let me know what probably went wrong?
