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">
<clusternodes>
<clusternode name="ustlvcmsp1954" nodeid="1"/>
<clusternode name="ustlvcmsp1955" nodeid="2"/>
<clusternode name="ustlvcmsp1956" nodeid="3"/>
<clusternode name="ustlvcmsp1957" nodeid="4"/>
<clusternode name="ustlvcmsp1958" nodeid="5"/>
</clusternodes>
<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="p1957" passwd=" xxxxxxxx "/>
<fencedevice agent="fence_vmware_soap" ipaddr="10.30.197.112"
login="rhfence" name="p1958" passwd=" xxxxxxxx "/>
</fencedevices>
</cluster>
clustat show:

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

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?
