Hi Some new stuff : I've added the "return" just at the begining of check_xml function in CommandHandler.py and now GUI works fine with my cluster.conf . But even when saving again as a new cluster.conf I always got the same error about local node name not found in cluster.conf. Alain Hi Thanks Patrick for information. And sorry about first message : cman not started: CCS does not have a nodeid for this node, run 'ccs_tool > addnodeids' to fix /usr/sbin/cman_tool: aisexec daemon didn't start It was effectively clear enough and I had fixed the problem, I just mismatch the error message when copy/paste in email. My problem was effectively in the second email, meaning : > cman not started: Can't find local node name in cluster.conf > /usr/sbin/cman_tool: aisexec daemon didn't start > [FAILED] I tried "cman_tool join -d " as you recommanded, it returns : [root@am2 log]# cman_tool join -d waiting for aisexec to start [MAIN ] AIS Executive Service RELEASE 'subrev 1358 version 0.80.3' cman not started: Can't find local node name in cluster.conf cman_tool: aisexec daemon didn't start [root@am2 log]# [MAIN ] Copyright (C) 2002-2006 MontaVista Software, Inc and contributors.

And when I launch the system-config-cluster GUI , I got errors : Relax-NG validity error : Extra element rm in interleave /etc/cluster/cluster.conf:25: element rm: Relax-NG validity error : Element cluster failed to validate content /etc/cluster/cluster.conf fails to validate My cluster.conf is : ================== <?xml version="1.0"?> <cluster config_version="1" name="TEST"> <fence_daemon clean_start="1" post_fail_delay="0" post_join_delay="3"/> <clusternodes> <clusternode name="am1" nodeid="1" votes="1"> <fence> <method name="1"> <device name="am1fence" option="reboot"/> </method> </fence> </clusternode> <clusternode name="am2" nodeid="2" votes="1"> <fence> <method name="1"> <device name="am2fence" option="reboot"/> </method> </fence> </clusternode> </clusternodes> <cman expected_votes="1" two_node="1"/> <fencedevices> <fencedevice agent="fence_ipmilan" ipaddr="162.29.1.116" login="administrator" name="am1fence" passwd="administrator"/> <fencedevice agent="fence_ipmilan" ipaddr="162.29.1.117" login="administrator" name="am2fence" passwd="administrator"/> </fencedevices> <rm> <failoverdomains> <failoverdomain name="testHA" ordered="0" restricted="0"> <failoverdomainnode name="am1" priority="1"/> <failoverdomainnode name="am2" priority="1"/> </failoverdomain> </failoverdomains> <service domain="testHA" name="test_am1" autostart="0" checkinterval="60"> <script file="/usr/sbin/test_am1" name="test_am1"/> </service> <service domain="testHA" name="test_am2" autostart="0" checkinterval="60"> <script file="/usr/sbin/test_am2" name="test_am2"/> </service> </rm> </cluster> Thanks for your help.
