Do I need to have a cross over cable between each node? Is it mandatory?<br>

Nop it doesn't.<br>
In your case, I'd check the network architecture and/or firewalling regarding multicast. You probably either have wrong iptables and/or a switch dropping your multicast corosync ring(s).<br>
<br>
Also, please, as Andreas said: try to communicate with us in a more efficient way: more context, more informations and more output (pasted somewhere).<br>
<br>
We are happy to help people, but we don't have to waste our time trying to understand what these exact people doesn't tell us because they are lazy.<br>
<br>
ps: also use 'corosync-objctl' ; it's a good command to debug rings and configurations.<br>
<br>
Cheers,<br>
Florian.<br>

Again the when i restarted the pacemaker and cman not the nodes are<br>
not in online, back to square 1.<br>
<br>
node1 shows only node1 online, and node2 says node2 online. I don't<br>
know what's happening in the background...<br>
<br>
Any advice would be appreciated..<br>
<br>
Thanks.<br>

I have configured CMAN as per the link<br>
<a href="http://clusterlabs.org/doc/en-US/Pacemaker/1.1-plugin/html-single/Clusters_from_Scratch/index.html#_configuring_cman" target="_blank">http://clusterlabs.org/doc/en-<u></u>US/Pacemaker/1.1-plugin/html-<u></u>single/Clusters_from_Scratch/<u></u>index.html#_configuring_cman</a> but<br>
when I type cman_tools nodes only one node is online even<br>
thought the cluster.conf is propogated in other node as well.<br>
<br>
what could be the reason, in node1, cman_tool nodes shows<br>
only node1 online, in node2 it shows only node2 is online.<br>
How to make two nodes as online, even thought CMAN service<br>
is running in both nodes.<br>
<br>
Thanks in advance.<br>
<br>
