well - i am still frustrated :-)

Some testing here shows following behaviour: 

if i boot my two nodes and start cman only (messaging) the cluster comes up. 
Testing now: if i do a hard shutdown on node2 - node1 begins to "fence" the 
node2 because this is a test environment i do a fence_ack_manual and boot the 
node2 again. after starting cman again node2 joins immediately the cluster. 
thats all without pacemaker.

if i do the same with cman+pacemaker running and resources started, the second
node will not join the cluster after rebooting it. 

so far for today
