[Pacemaker] Resources don't start on second node after ping fails

[Benjamin.Benz at t-systems.com]

Hi everybody!

I fixed this 'problem'... 
My drbd-resource wasn't connected. m(
The configuration of the ping resource and location were correct. I implemented Marco's advice but I'm sure my solution would've also worked.
The failover works just fine right now.

Thanks for reading!

Hi there!

I've got a problem with the configuration.
I'm using Pacemaker 1.0.7 to move my database from node1 to node2. Everything works fine when I migrate the resources manually or pull out the power plug.
Since I want the database to be available in case of network problems I tried to integrate a ping resource as you can see below.
When I pull out the network cable the resources stop on node1 but don't start on node2.

crm_mon output:

Online: [ bb-node1 bb-node2 ]

 Master/Slave Set: ms_drbd_ora
     Slaves: [ bb-node2 ]
     Stopped: [ drbd_ora:1 ]
 Clone Set: connected
     Started: [ bb-node1 bb-node2 ]


I guess there's something wrong with my configuration of the location but I can't figure it out.
It would be great if someone could help me out!

If you have other helpful hints concerning my config feel free to answer!

Regards
Benjamin Benz
