Ah yes!
You did define a ping resource, but did not clone it. So I runs only one one 
node. You also defined a colocation constraint that allows the drbd only run on 
a node where the pingd is running. So the DRBD cannot run.

Solution:
1) clone the pingd
2) Delete you colocation constraint. It is useless.
3) Make a location constatint the allows the ip address only run on a node 
that gets points from the pingd.
