Hi,

Would you mind not using this mailing list as a kind of chat channel 
where you send an email to this list every few minutes something happens 
or does not happen with your cluster? Clustering is complicated, takes a 
lot of time to learn and it's not realistic to think you can start on 
Monday and be in production on Friday. So just take a step back, read 
all the docs and slowly work your way through this magic.

General Concepts section:
http://clusterlabs.org/doc/Ordering_Explained.pdf
http://clusterlabs.org/doc/Colocation_Explained.pdf
http://clusterlabs.org/doc/crm_fencing.html
http://clusterlabs.org/doc/acls.html

You said you used CentOS 6.4 so I guess that would be this one:

Pacemaker 1.1 for CMAN or Corosync 1.x:
http://clusterlabs.org/doc/en-US/Pacemaker/1.1-plugin/html-single/Clusters_from_Scratch/index.html

There's also this one:
Red Hat Quickstart: http://clusterlabs.org/quickstart-redhat.html

And this one for everything you ever wanted to know about pacemaker:
http://clusterlabs.org/doc/en-US/Pacemaker/1.1-plugin/html-single/Pacemaker_Explained/index.html

Then also read: http://www.catb.org/esr/faqs/smart-questions.html

And then if you have a question email this list with at least your 
setup, IP addresses, configuration and logs and exact steps you have 
taken (cli commands & output). And for a quick question you would 
obviously use Google and also search this list with Google using 
site:http://oss.clusterlabs.org/pipermail/pacemaker/ <your search terms> 
or you could join the #linux-cluster irc channel on freenode.net and ask 
there (due to timezone differences be patient for an answer so lurk around).

Good luck!

Regards,
Patrick
