Re: [Linux-cluster] 3 node cluster problems



Did you load the Cluster software via Conga or manually ? You would have had to load
luci on one node and ricci on all three.

Try copying the modified /etc/cluster/cluster.conf from csarcsys1 to the other two nodes. Make sure you can ping the private interface to/from all nodes and reboot. If this does not work
post your /etc/cluster/cluster.conf file again.

Yes
I also rebooted again just now to be sure.

When you changed the nodenames in the /etc/lcuster/cluster.conf and made

sure the /etc/hosts
file had the correct nodenames (Ie. 10.0.0.100 csarcsys1-eth0 csarcsys1-eth0.xxxx.xxxx.xxx.)
Did you reboot all the nodes at the sametime ?

No luck. It seems as if csarcsys3 thinks its in his own cluster

You will also, need to make sure the clustered nodenames are in your /etc/hosts file. Also, make sure your cluster network interface is up on all nodes and that the
/etc/cluster/cluster.conf are the same on all nodes.

The last post is incorrect.

Fence is still hanging at start up.

Here's another log message.

try removing the fully qualified hostname from the cluster.conf file.
