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.

[root at phys-file01 ~]# crm configure show
