[Pacemaker] Fence device 'pcmk' not found and rhel6 arhitecture

 Thanks for the clarification - that worked !

 So I now have two test setups, one with pacemaker/cman/corosync and
 one with just pacemaker/corosync as described in the clusters from scratch
 document. Which is the better architecture for a cluster I am installing mid year ?
 From what I can see the cman setup does not allow for redundant corosync rings nor
 crossover cables(ie https://access.redhat.com/knowledge/articles/40051 ) while
 pacemaker/corosync does not have this restriction. For a simple two-node drbd cluster
 cman pacemaker/corosync(or heartbeat) looks like a better choice. Am I reading this 
 correctly ? Also from what I've read it looks like the official redhat clustering is
 moving to pacemaker/corosync   ... when ?

I made a mistake. The line:

[ONE] # ccs -f /etc/cluster/cluster.conf --addfencedev pcmk-redirect

should have been

[ONE] # ccs -f /etc/cluster/cluster.conf --addfencedev pcmk agent=fence_pcmk
