Good afternoon, I'm trying to form my first cluster of two nodes, using iLO fence devices. I need some help because I can't find what I've missed. My main problem is that the "service cman start" reboots the other node and I can't form the two nodes cluster. I'm using (at both nodea and nodeb, they are on the same VLAN and pings each other ok): [root@nodea ~]# uname -a Linux nodea 2.6.18-164.15.1.el5 #1 SMP Wed Mar 17 11:30:06 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux [root@nodea ~]# rpm -qa |grep cman cman-2.0.115-1.el5_4.9 [root@nodea ~]# cat /etc/cluster/cluster.conf (nodeb has the same file) <?xml version="1.0" ?> <cluster alias="VCluster" config_version="5" name="VCluster"> <fence_daemon post_fail_delay="0" post_join_delay="25"/> <clusternodes> <clusternode name="nodea" nodeid="1" votes="1"> <fence> <method name="1"> <device name="nodeaILO"/> </method> </fence> </clusternode> <clusternode name="nodeb" nodeid="2" votes="1"> <fence> <method name="1"> <device name="nodebILO"/> </method> </fence> </clusternode> </clusternodes> <cman expected_votes="1" two_node="1"/> <fencedevices> <fencedevice agent="fence_ilo" hostname="nodeacn" login="user" name="nodeaILO" passwd="hp"/> <fencedevice agent="fence_ilo" hostname="nodebcn" login="user" name="nodebILO" passwd="hp"/> </fencedevices> <rm> <failoverdomains/> <resources/> </rm> </cluster> When I start the cman service, it hangs up for some time at the "Starting fencing..." step and after those configured 25secs it fences nodeb and reboots it.

I guess I'm missing something at the cluster.conf file??? I can't find what I'm making wrong. Thanks for any help! Alex Re |
