Problem in starting the alternate machine in a cluster

[Shibu_2]

Hi masters,

I have found one problem while trying to run cmrunnode from alternate client in a two node cluster.



cmrunnode : Unable to determine the nodes on the current cluster
cmrunnode : Either no cluster configuration file exists, or the file is corrupt
ed, or /usr/lbin/cmclconfd is unable to run
Gave up attempting to receive a connection from Beta3
Failed to lookup /cluster in configuration database.
Fail to load data from configuration database



The package is up and running and the status of alternate link is shown halted in cmviewcl.
The cmviewcl is getting hanged while issued from Alternate Machine


Pls help in solving this

What it looks like is that the /etc/cmcluster/cmclconfig on the other node is corrupt. You can try to get the configuration and then re-apply the configuration on the other node. Do this.
1. run cmgetconf and get the present cluster configuration.
#cmgetconf -v -c outputfile
2. If it doesn't have the alternate node, edit the file and put that node too in the outputfile
3. Then cmcheckconf -v -C outputfile
4. cmapplyconf -v -C outputfile

This will add the node to the cluster and rebuild the cluster configuration on the alternate node

Do you have the correct entries in your host equivalency file?
check root's .rhosts, or more likely /etc/cmcluster/cmclnodelist
The file must contain entries for ALL nodes in hte cluster.
