Hi Noel,

Thanks for the quick reply, I really appreciate it. I found out that after
I kill the nginx at the node1. I run the command *pcs status* and I got
below info.

[root at node2 ~]# pcs status
Cluster name: cluster_web
Last updated: Sun Aug  9 12:49:20 2015
Last change: Sun Aug  9 09:24:37 2015 via cibadmin on node1
Stack: corosync
Current DC: node2 (2) - partition with quorum
Version: 1.1.10-29.el7-368c726
2 Nodes configured
2 Resources configured

Online: [ node1 node2 ]

Full list of resources:

 Resource Group: test
     nginx      (ocf::heartbeat:nginx): Started node2
     virtual_ip (ocf::heartbeat:IPaddr2):       Started node2

Failed actions:
* nginx_monitor_60000 on node1 'not running' (7): call=11, status=complete,
last-rc-change='Sun Aug 9 12:34:47 2015', queued=0ms, exec=0ms*

Looks like the nginx monitor is failing on the node1 and causing the issue.
After I restart the cluster node 1, it take back the VIP and Nginx resource
again, because it got a higher score than the node2. But is it possible to
make the node1 recovery it's nginx monitor on it own? Thanks again for your
