DRDB error

I implemented this today: http://library.linode.com/linux-ha/ip-f … igure_drbd">http://library.linode.com/linux-ha/ip-failover-heartbeat-pacemaker-drbd-mysql-ubuntu-10.04#installandconfigure_drbd

What a job! However, I'm now running into an error. I believe I suffered a split brain(user error?) which is giving me the following:

Failed actions:
    fs_mysql_start_0 (node=ha2, call=26, rc=1, status=complete): unknown error
    fs_mysql_start_0 (node=ha1, call=10, rc=1, status=complete): unknown error

My logs are not revealing a whole lot and my familiarity with this config is making it hard to troubleshoot. Any guidance/direction would be greatly appreciated.

Details:

Ubuntu 10.04

2 nodes - ha1/ha2

Everything worked earlier but then I performed a mysql import and things shit themselves…

So, as I said, any guidance will be greatly appreciated. Thank you.

EDIT: A little more output from crm_mon:

Online: [ ha1 ha2 ]

 Master/Slave Set: ms_drbd_mysql
     Masters: [ ha1 ]
     Slaves: [ ha2 ]
 Master/Slave Set: ms_drbd_webfs
     Masters: [ ha1 ]
     Slaves: [ ha2 ]

Everything works fine when I take down ha1. ha2 takes over master. But when I bring ha1 back up, ha1 takes over msdrbdwebfs but not msdrbdmysql

What a mess, right?!
