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

[Marco van Putten]

Hi Benjamin,

Congratulations!
Do you mean not connected as in physicly not connected?

I'm no expert on the matter but I just ran into the "number" problem a 
couple of weeks ago myself.
Maybe in a newer version this is no longer an issue...

Bye,
Marco.
