Hey Guys,<br>
<br>
The OS am running is CentOS 6.4 (64bit) and I have disabled IPtables and<br>
SeLinux.<br>
<br>
My goal is to make Apache Tomcat as HA. As a first step thought of<br>
testing with Apache.<br>
<br>
My network setup is like this,<br>
Node1 is connected to switch<br>
Note2 is connected to switch.<br>
<br>
My cluster.conf file is as follows,<br>
[root@test01 ~]# cat /etc/cluster/cluster.conf<br>
<?xml version="1.0"?><br>
<cluster config_version="1" name="mycluster1"><br>
<logging debug="off"/><br>
<clusternodes><br>
<clusternode name="test01" nodeid="1"><br>
<fence><br>
<method name="pcmk-redirect"><br>
<device name="pcmk" port="test01"/><br>
</method><br>
</fence><br>
</clusternode><br>
<clusternode name="test02" nodeid="2"><br>
<fence><br>
<method name="pcmk-redirect"><br>
<device name="pcmk" port="test02"/><br>
</method><br>
</fence><br>
</clusternode><br>
</clusternodes><br>
<fencedevices><br>
<fencedevice name="pcmk" agent="fence_pcmk"/><br>
</fencedevices><br>
</cluster><br>
<br>
<br>
And @some point of time am able to see both nodes are registered,<br>
[root@test01 ~]# cman_tool nodes<br>
Node Sts Inc Joined Name<br>
1 M 104 2013-09-17 02:01:11 test01<br>
2 M 108 2013-09-17 02:15:07 test02<br>
<br>
And @sometimes with crm_mon -1, I get the following<br>
<br>
[root@test01 ~]# crm_mon -1<br>

Ok, if you are still unhappy with CMAN check your switch for multicast.<br>
<br>
>From there, I assume you are happy with cman otherwise there are no reasons to start pacemaker, but you did, so you get my point ;)<br>
<br>
This kind of errors often indicates that your /etc/hosts or DNS is wrong and pacemaker has a hard time to map hostnames and IPs, etc (not sure about the internals there...)<br>
Get rid of the invalid nodes by editing the configuration; stop pacemaker; fix your resolutions and retry.<br>
<br>
In the entire process, I usually use FQDN in my cluster.conf file, and I add them and the corresponding ring IP in my /etc/hosts file on all nodes. I also use the same FQDN in my pacemaker configuration.<br>
<br>
Cheers<br>

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

when I type cman_tools nodes only one node is<br>
online even<br>
thought the cluster.conf is propogated in other<br>
node as well.<br>
<br>
what could be the reason, in node1, cman_tool nodes<br>
shows<br>
only node1 online, in node2 it shows only node2 is<br>
online.<br>
How to make two nodes as online, even thought CMAN<br>
service<br>
is running in both nodes.<br>

Thanks in advance.<br>
