Hi , <br>
<br>
I am configuring active/active clustering of two centos-6.2
virtual machines. I am using gfs2 filesystem as common storage on
both the VM's. We need rpm pacakages namd <font color="#ff6666"><small>"</small>dlm
<font color="#000000">and</font> kernel-module-extra<small>"</small></font>
for active/active clustering as per documentation.<br>
<br>
Any idea how can i get these packages for centos-6.2 so that i
configure the active /active clustering using gfs2.<br>
<br>
Is there any documentation on the web for pacemaker in centos-6.2 ?<br>
<br>
Thanx in advance!!!!!!!<br>
<br>
Regards<br>

I am trying to configure clustering of two virtual machines(
Centos-6.2
<br>
,KVM hypervisor). Both the machines are running on different
VLAN's i.e
<br>
both machines have different gateway.
<br>
<br>
My doubt : Is it necessary that both the VM's should be on
the same
<br>
VLAN and should have same gateway ? to configure clustering.
If it is
<br>
not , then what changes need to be done on VMs so that we can
do the
<br>
clustering.

corosync uses multicast paket. so be sure that multicast traffic
get routed
<br>
correctly between your networks. As an alternative you could use
udp unicast
<br>
as a transort. Please see man corosync.conf the the unicast
option.

[root@node1 ~]# corosync-cfgtool -s

Printing ring status.
<br>
Local node ID 16777343
<br>
RING ID 0
<br>
id = 127.0.0.1
<br>
status = ring 0 active with no faults
<br>
<br>
As per the the documentation , i should get static ip address
instead of
<br>
the localhost address , same is happening on both VMs , Can
you guys
<br>
suggests what can be done so that my both nodes join the
cluster.

configure corosync correctly. Than it will find your interface.
