Hi all,
I am using Red Hat cluster 6.2.0 (version shown with cman_tool
version) on Red Hat 5.5
I am on host that has multiple network interfaces and all(or some) of
which may be active while I tried to bring up my IP resource up.
My cluster is of simple configuration -
It has only 2 nodes, and
do I have to add virtual interface manually (as above or any other
method?) before I could start service with IP resource under it?
Thanks

Thank you for your response. My two hosts have multiple network

IP corresponding to cluster node name for both hosts, should be in
the same subnet before a cluster could bring virtual IP up

Hi all,
Taking this question from another thread, here is a challenge that I am facing -
Following is simple cluster configuration -
Node 1, node 2, node 3, and node4 are part of cluster, its
unrestricted unordered fail-over domain with active - active nxn
configuration
So a node 2 can get
also setting up monitoring.
The monitoring package can then notify you if any cluster member fails.

If service is started (i.e. running on some node), exit code of this command

Is this right and going to be continued in subsequent cluster
