[Pacemaker] pacemaker-mgmt (pygui) on fedora 20

Hi all,

In the past I have put to good use the pacemaker-mgmt  (crm_gui) , mostly when I have to
delegate management of cluster to third person, so much easier to explain ...
So for latest cluster I managed to get pacemaker-mgmt working on Fedora 20 (since it is not so straight forward
I included rough procedure below, for those interested),  not tested to the extent yet, but all frequently used
operations work (creating resource, starting/stopping resource,  put cluster/resource in unmanaged state ...)

My question is following:

Before the mgmtd was started by corosync like this:


service {
	# Load the Pacemaker Cluster Resource Manager
	name: pacemaker
	ver:  0
	use_mgmtd: 1
that is apparently not the case anymore, so I start mgmtd l by hand like this:

/usr/lib64/heartbeat/mgmtd -v &

This mostly work. But if corosync/pacemaker  is not started  or just starting it fails miserably with message Aborted.
If I wait that cluster comes up and online then it works.

My question is - how to start mgmtd by cluster itself properly as before ?

I use:
