The worse thing is sometimes, I got error message to say failed to update config file, on node 1. but check log on node2, it shows :Update of cluster.conf complete (version n -> n+1 ). It really confused me. <div>On 7/6/07, siman hew <<a href="mailto:simanhew@gmail.com">simanhew@gmail.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hello, I have one problem that I do not know it is a feature or a bug of cluster. I have a cluster with 3 nodes, two are running, and one is stopped, on RHEL5. I would like to add a failover domain, and changed cluster.conf, then ccs_tool update it. I got error message: Failed to receive COMM_UPDATE_COMMIT_ACK from node3. Hint: Check the log on node3 for reason. Failed to update config file or similar error message. I tried on Conga, it does not work too. I just wonder it is a bug or a feature -- we can not update cluster.conf if there is one node is dead? Thanks in advanced. Siman </blockquote></div>
