Hello,
I have a 2 node HA cluster and I am configuring the httpd service as
active-active. I want to run httpd service in both the cluster nodes
simultaneously. I have configured 2 failover domains FD1 and FD2.
FD1 = p6pv1(priority 1) & p7pv1(priority 2)
FD2 = p6pv1(priority 2) & p7pv1(priority 1)
nodes(both installed RHEL5.2):
--------------------------
p6pv1: 10.1.40.204
p7pv1: 10.1.40.206
and here's the "/etc/cluster/cluster.conf":
-----------------------------------------
[r...@p6pv1 ~]# cat /etc/cluster/cluster.conf

</service>
</rm>
</cluster>
[r...@p6pv1 ~]#
-----------------------------------------
When these two nodes are both running, I am seeing configured services
httpd1 and httpd2 are running on p6pv1 and p7pv1 respectively.

p7pv1.tr.unisys.com started
---------------------------------------------------
But in real the httpd service is running only at one node at any
particular instant of time. Here expected behavior is httpd should run
on both the nodes. I am getting below log messages.

Can some one help me to fix this issue? Any suggestions appreciated.
Thanks and Regards,
