Please configure fencing. If you don't, it _will_ cause you problems.

Hi Digimer,
No we're not supporting multicast. I'm trying to use Broadcast, but Redhat support is saying better to use transport=udpu. Which I did set and it is complaining time out.
I did try to set broadcast, but somehow it didn't work either.
Let me give broadcast a try again.
Thanks,
Vinh

It looks like a network problem... Does your (virtual) switch support multicast properly and have you opened up the proper ports in the firewall?

Hi Digimer,
Yes, I just did. Looks like they are failing. I'm not sure why that is.
Please see the attachment for all servers log.
By the way, I do appreciated all the helps I can get.

Quorum is enabled by default. I need to see the entire logs from all five nodes, as I mentioned in the first email. Please disable cman from starting on boot, configure fencing properly and then reboot all nodes cleanly. Start the 'tail -f -n 0 /var/log/messages' on all five nodes, then in another window, start cman on all five nodes. When things settle down, copy/paste all the log output please.

Yes, I did made changes with: <fence_daemon post_join_delay="30"/> the problem is still there. One thing I don't know why cluster is looking for quorum?
I did have any disk quorum setup in cluster.conf file.
Any helps can I get appreciated.

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.

You don't configure the fencing for the nodes... If anything causes a fence, the cluster will lock up (by design).

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?

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:

corosync is stopped
