RE: [Linux-cluster] 3 node cluster problems



Sorry but security here will not allow me to send host files

BUT.


I was getting this in /var/log/messages on csarcsys3

Mar 25 15:26:11 csarcsys3-eth0 ccsd[7448]: Cluster is not quorate.
Refusing connection.
Mar 25 15:26:11 csarcsys3-eth0 ccsd[7448]: Error while processing
connect: Connection refused
Mar 25 15:26:12 csarcsys3-eth0 dlm_controld[7476]: connect to ccs error
-111, check ccsd or cluster status
Mar 25 15:26:12 csarcsys3-eth0 ccsd[7448]: Cluster is not quorate.
Refusing connection.
Mar 25 15:26:12 csarcsys3-eth0 ccsd[7448]: Error while processing
connect: Connection refused


I had /dev/vg0/gfsvol on these systems.

I did a lvremove 

Restarted cman on all systems and for some strange reason my clusters
are working.

It doesn't make any sense.

I can't thank you enough for your help.......!!!!!!


Thanks.

Subject: Re: [Linux-cluster] 3 node cluster problems

I am currently running several 3-node cluster without a quorum disk. 
However, If you want your cluster to run
if only one node is up then you will need a quorum disk. Can you send 
your /etc/hosts file
for all systems, Also, could there be another node name called 
csarcsys3-eth0 in your NIS or DNS

I configured some using Conga and some with system-config-cluster. When 
using the system-config-cluster
I basically run the config on all nodes; just adding the nodenames and 
cluster name. I reboot all nodes
to make sure they see each other then go back and modify the config
files.

The file /var/log/messages should also shed some light on the problem.
