 # OCF does not include the concept of master/slave resources so we
 #   need to extend it so we can discover a resource's complete state.
 #
 # OCF_RUNNING_MASTER:  
 #    The resource is in "master" mode and fully operational
 # OCF_FAILED_MASTER:
 #    The resource is in "master" mode but in a failed state
 # 
 # The extra two values should only be used during a probe.
 #
 # Probes are used to discover resources that were started outside of
 #    the CRM and/or left behind if the LRM fails.
 # 
 # They can be identified in RA scripts by checking for:
 #   [ "${__OCF_ACTION}" = "monitor" -a "${OCF_RESKEY_CRM_meta_interval}" = "0" ]
 # 
 # Failed "slaves" should continue to use: OCF_ERR_GENERIC
 # Fully operational "slaves" should continue to use: OCF_SUCCESS
