[Pacemaker] monitor on disabled nodes

[Radoslaw Garbacz]

Sorry for not being specific.

The agent is meant to run only on a specific node (the head), and by
constraints is disabled on all other nodes.

'pcs constraint' reports:
Location Constraints:
  Resource: dbx_nfs_head
    Enabled on: ip-10-138-14-225
    Disabled on: ip-10-151-14-34 ip-10-238-146-54


'pcs status' reports:
Failed actions:
    dbx_nfs_head_monitor_0 (node=ip-10-238-146-54, call=1127, rc=6,
status=complete): not configured
    dbx_nfs_head_monitor_0 (node=ip-10-151-14-34, call=1127, rc=6,
status=complete): not configured


So it has been started with this constraint. The agent requires certain
configuration, which is present only on the head node, so I would like to
keep it away from all other nodes, but as far as I understand, the
pacemaker needs to check if it is running, so I would like to recognize
this situation and skip the check on all nodes except the head.

Thanks,
