Hi all, I have a problem with my RHEL 5.2 a 2 node cluster running on IBM X3650. My cluster is configured for fencing on IBM RSAII via system-config-cluster, with only one network interface, no shared storage and I have followed the Red Hat Cluster suite for installation. At the first look, no syntax error in my cluster.conf but when I'm going to start the cman and the rgmanager daemons on primary node the other node reboot or poweroff immediately. Can anyone help me? Thanks in advance Loris My cluster.conf: <?xml version="1.0" ?> <cluster alias="newsocks" config_version="10" name="newsocks"> <fence_daemon post_fail_delay="60" post_join_delay="30"/> <clusternodes> <clusternode name="socks1" nodeid="1" votes="1"> <fence> <method name="1"> <device name="RSA_1"/> </method> </fence> </clusternode> <clusternode name="socks2" nodeid="2" votes="1"> <fence> <method name="1"> <device name="RSA_2"/> </method> </fence> </clusternode> </clusternodes> <cman expected_votes="1" two_node="1"/> <fencedevices> <fencedevice agent="fence_rsa" ipaddr="<a href="http://10.242.164.126">10.242.164.126</a>" login="xxxxx" name="RSA_1" passwd="xxxxx"/> <fencedevice agent="fence_rsa" ipaddr="<a href="http://10.242.164.128">10.242.164.128</a>" login="xxxxx" name="RSA_2" passwd="xxxxx"/> </fencedevices> <rm> <failoverdomains> <failoverdomain name="domso" ordered="1" restricted="1"> <failoverdomainnode name="socks1" priority="1"/> <failoverdomainnode name="socks2" priority="2"/> </failoverdomain> </failoverdomains> <resources> <ip address="<a href="http://10.242.156.100">10.242.156.100</a>" monitor_link="1"/> </resources> <service autostart="1" domain="domso" name="servso" recovery="relocate"> <ip ref="<a href="http://10.242.156.100">10.242.156.100</a>"> <script file="/etc/init.d/ss5" name="sockss5"/> </ip> </service> </rm> </cluster>
