I set rsc_order.

But, clone started in the first node after an IPaddr resource caused a
monitor error in all nodes.
If my understanding is not wrong, does not the clone stop in the first node
by this rsc_order?

--------------------------------------------------------------------
Node: rh44-1 (4be91ff0-c0da-46a1-b913-acf19d8fcfb6): online
Node: rh44-2 (2f14e3d7-aa37-4e95-9634-cd44ced9bea7): online

Clone Set: clone0
    clone0-diskcheck:0  (heartbeat::ocf:Dummy): Stopped
    clone0-diskcheck:1  (heartbeat::ocf:Dummy): Started rh44-1
--------------------------------------------------------------------

fail-count of all nodes goes up to 1.
Though fail-count of ipaddr goes up if rsc_order is effective, why does the
clone start?

I attached a file just to make sure.

I do not ignore stonith.
I want to use stonith as the last method.
(For example I want to wait for the operator's operation without stonith. )

Is the change not to start the clone resource again by this specification
difficult( stonith = false, on_fail = fence)?
If the change is difficult, I understand as the current specification.
