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.
I want to thank Michael for pointing out my mistake. I have also
migrated away from using heartbeat to openais.
I have noticed that more often than not after a node is rebooted,
openais starts, but crm fails to start correctly. I usually have to kill
it with pkill -9 aisexec, then start it again and then it usually works
fine.
In any case, here is my final configuration which works for 2 drbd
resources to run a file server with nfs and samba.
[r...@phys-file01 ~]# crm configure show
