1. May I know Conga must use IGMP network device? I using non-managed switch, login conga GUI and create cluster but nothing happen in /etc/cluster, the cluster.conf cannot generate.
2. I manual create a cluster.conf in /etc/cluster the cluster can start up node1 and create fencing device but node2 cannot start...with following error:

[root@nodeb cluster]# service cman start
Starting cluster:
Checking Network Manager... [ OK ]
Global setup... [ OK ]
Loading kernel modules... [ OK ]
Mounting configfs... [ OK ]
Starting cman... Relax-NG validity error : Extra element cman in interleave
tempfile:13: element cman: Relax-NG validity error : Element cluster failed to validate content
Configuration fails to validate
Timed-out waiting for cluster
[FAILED]

3. Once I start service of rgmanager will cause nodeb shutdown. May I know what happen?

Hi

yes that's right i am also facing same problem
but i used GUI system-config-cluster you can try it at runlevel 5

Hi

Redhat Enterprise 6.0 also support system-config-cluster. I read the manual said system-config-cluster not support in Redhat Ent 6.0

i tried it at rhel5.7 not in rhel6
