I appreciate the quick response. I am relatively new to pacemaker, so I am
trying to do this with the crm_gui. I just figured out how to get an XML
representation of the resources and constraints configuration that I have. I
will look ath these links. Also, here is the XML configuration

Yes, it is definitely possible.
http://clusterlabs.org/doc/en-US/Pacemaker/1.1-crmsh/html-single/Pacemaker_Explained/index.html#_group_constraints
and
http://clusterlabs.org/doc/en-US/Pacemaker/1.1-crmsh/html-single/Pacemaker_Explained/index.html#_clone_constraints
shows the xml representation in the cib.
Are you using a configuration tool like crm or pcs? If so this may be a
problem with that project.
