Nice that you tell us that you read all. But did you also read "Clusters from 
the scratch"? Especially chapter 5.1

http://www.clusterlabs.org/doc/en-
US/Pacemaker/1.1/html/Clusters_from_Scratch/ch05.html

where it says:

"Before we make any changes, its a good idea to check the validity of the 
configuration. 
(...)
As you can see, the tool has found some errors. 
(...)
To disable STONITH, we set the stonith-enabled cluster option to false. 

crm configure property stonith-enabled=false
(...)
"
Please als read 5.2 and 5.3 for a good start.

Cheers,
