Hi Guys!
I'm having a strange problem with pacemaker-heartbeat cluster when I put it
in a maintenance-mode.
First of all, let me show my configuration:
[ Pacemaker ]

============
Online: [ test-lb01 test-lb02 ]
IP-rsc_apache (ocf::heartbeat:IPaddr2): Started test-lb01
Nginx-rsc (ocf::heartbeat:nginx): Started test-lb01
Clone Set: ClusterMon-clone [ClusterMon]
Started: [ test-lb01 test-lb02 ]
====================
So, everything is working. But now, if put enable the maintenance-mode on
the cluster, both nodes get rebooted:
crm(live)# configure property maintenance-mode="true"
Then in the logs:

For some reason, pacemaker found something that it didn't like, and
crashed, but I'm not understanding what.
Could someone throw me some hints about that?
Thanks in advance
Have a nice weekend!
