[Pacemaker] Cannot start the failed MySQL master as a new slave?

[quanta]

As Patrick pointed here:
http://serverfault.com/questions/405982/mysql-pacemaker-cannot-start-the-failed-master-as-a-new-slave

I need to set the additional variables to tells the script its a
master/slave resource.
So, I've appended the following variables to my |~/.bash_profile|:

|export OCF_RESKEY_CRM_meta_clone_max="2"
export OCF_RESKEY_CRM_meta_role="Slave"|

Make it take effect |. ~/.bash_profile| and manually start mysql resource:

|sh -x /usr/lib/ocf/resource.d/percona/mysql start|: http://fpaste.org/EMwa/

and it works fine:

|mysql> show slave status\G

I've been turing on the debug, stop corosync and restart, here're the
logs: http://fpaste.org/mZzS/
As you can see, nothing details than 'unknown error':

Any thoughts?
