RHEL 6 Cluster Configuation problem

Latest response

Hi All,

We have 2-node cluster running RHEL 6 but we encounter cluster configuration error.

Error:

Jun 25 02:34:48 host2 fenced[4031]: fence host2 dev 0.0 agent fence_bladecenter result: error from agent
Jun 25 02:34:48 host2 fenced[4031]: fence host2-host failed

If I add:


Invalid configuration

[root@host2 cluster]# cman_tool version -r
Relax-NG validity error : Extra element fence in interleave
tempfile:5: element fence: Relax-NG validity error : Element clusternode failed to validate content
tempfile:4: element clusternode: Relax-NG validity error : Element clusternodes has extra content: clusternode
Configuration fails to validate
cman_tool: Not reloading, configuration is not valid

</cluster>

Appreciate all you can help to solve problem, since we can't specify blade number and can't fence failed node.

Thomas
