Hello All,

  I'm new to pacemaker so please forgive me if this is in a faq 
somewhere, I haven't been able to find it!
I am trying to set up a failover config for mysql using the following setup:

primitive mysqlvip ocf:heartbeat:IPaddr params ip="xx.xx.xx.xx"
primitive mysqlfs ocf:heartbeat:Filesystem params device="-L mysql" 
directory="/var/lib/mysql" fstype="ext3"
primitive mysqlserver ocf:heartbeat:mysql params 
binary="/usr/bin/mysqld_safe" op monitor interval="60s" timeout="30s"
primitive st-null stonith:null params hostlist="mysql1 mysql2"
group mysqlservice mysqlvip mysqlfs mysqlserver
clone fencing st-null
location mysql1loc mysqlservice 200: mysql1
location mysql2loc mysqlservice 150: mysql2
colocation mysql_ip_with_fs inf: mysqlvip mysqlfs
colocation mysql_server_with_fs inf: mysqlserver mysqlfs
order mysql_fsbeforeserver inf: mysqlfs mysqlserver

And it looks to be working great. When I start the configuration three 
resources are started on node mysql1. When I switch off node1 by 
shutting down the heartbeat service I can see all my resources moving 
over to node mysql2. However when I pull the plug on node mysql1 by 
switching it off, my services are not moving over. Instead my services 
are listed as having been started on node mysql1 (which is down!). This 
is the output of crm_mon -r:

Full list of resources:

Clone Set: fencing
        Stopped: [ st-null:0 st-null:1 st-null:2 st-null:3 st-null:4 
st-null:5 ]

I must be missing something but I haven't yet found it.

Any pointers would be appreciated.

Thanks,
  Mark
