Hello Digimer,
Yes, I would agrre with you RHEL6.4 is old. We patched monthly, but I'm not sure why these servers are still at 6.4. Most of our system are 6.6.
Here is my cluster config. All I want is using cluster to have BGFS2 mount via /etc/fstab.
root@ustlvcmsp1955 ~]# cat /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster config_version="15" name="p1954_to_p1958">

<clusternode name="ustlvcmsp1958" nodeid="5"/>

You don't configure the fencing for the nodes... If anything causes a
fence, the cluster will lock up (by design).
<fencedevices>
<fencedevice agent="fence_vmware_soap" ipaddr="10.30.197.108" login="rhfence" name="p1954" passwd="xxxxxxxx"/>
<fencedevice agent="fence_vmware_soap" ipaddr="10.30.197.109" login="rhfence" name="p1955" passwd=" xxxxxxxx "/>
<fencedevice agent="fence_vmware_soap" ipaddr="10.30.197.110" login="rhfence" name="p1956" passwd=" xxxxxxxx "/>
<fencedevice agent="fence_vmware_soap" ipaddr="10.30.197.111" login="rhfence" name="p1957" passwd=" xxxxxxxx "/>
<fencedevice agent="fence_vmware_soap" ipaddr="10.30.197.112" login="rhfence" name="p1958" passwd=" xxxxxxxx "/>
</fencedevices>
</cluster>

I need to make them all online, so I can use fencing for mounting shared disk.
Thanks,

What about the log entries from the start-up? Did you try the
post_join_delay config?

Subject: Re: needs helps GFS2 on 5 nodes cluster
My first though would be to set <fence_daemon post_join_delay="30" /> in cluster.conf.
If that doesn't work, please share your configuration file. Then, with all nodes offline, open a terminal to each node and run 'tail -f -n 0 /var/log/messages'. With that running, start all the nodes and wait for things to settle down, then paste the five nodes' output as well.
Also, 6.4 is pretty old, why not upgrade to 6.6?

Hello Cluster guru,
I'm trying to setup Redhat 6.4 OS cluster with 5 nodes. With two nodes
I don't have any issue.
But with 5 nodes, when I ran clustat I got 3 nodes online and the
other two off line.
When I start the one that are off line. Service cman start. I got:
[root@ustlvcmspxxx ~]# service cman status
corosync is stopped
[root@ustlvcmsp1954 ~]# service cman start
Starting cluster:

Starting cman... [ OK ]
Waiting for quorum... Timed-out waiting for cluster
[FAILED]
Stopping cluster:

Stopping gfs_controld... [ OK ]
Stopping dlm_controld... [ OK ]
Stopping fenced... [ OK ]

Can you help?
Thank you,
