For some reason, the last time I tried to post this, it didn't work (if it did, I apologize for the repeat), so I'm posting it again... I have 8 Dell servers all loaded with Redhat 5.3. The machines have an external and internal IP address. The cluster is configured on the internal ip address. The cluster appears to be working fine except for fencing. I try to manually fence a node, but get a connection error [root@w002 ~]# fence_node <a href="http://lb001.domain.com/" target="_blank">lb001.domain.com</a> agent "fence_drac5" reports: Unable to connect/login to fencing device I was able to get the fence_drac5 command to work directly by adding the "-x" option for using SSH. It says the connection times out, but it does shut down the other machine [root@w002 ~]# fence_drac5 -a 165.289.178.221 -l root -p pass -x <a href="http://lb001.domain.com/" target="_blank">lb001.domain.com</a> Connection timed out Why does the connection time out? And how do I add the "-x" option to the cluster.conf file so that the fencing agent can connect? Here are my /etc/hosts and /etc/cluster/cluster.conf files. ##############################<div id=":322" class="ii gt">################/etc/hosts 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 #eth0 -- p=public interface 165.289.178.111 w001p <a href="http://w001p.domain.com/" target="_blank">w001p.domain.com</a> 165.289.178.112 w002p <a href="http://w002p.domain.com/" target="_blank">w002p.domain.com</a> 165.289.178.113 w003p <a href="http://w003p.domain.com/" target="_blank">w003p.domain.com</a> 165.289.178.121 lb001p <a href="http://lb001p.domain.com/" target="_blank">lb001p.domain.com</a> 165.289.178.122 lb002p <a href="http://lb002p.domain.com/" target="_blank">lb002p.domain.com</a> 165.289.178.124 db001p <a href="http://db001p.domain.com/" target="_blank">db001p.domain.com</a> 165.289.178.125 db002p <a href="http://db002p.domain.com/" target="_blank">db002p.domain.com</a> 165.289.178.126 dev001p <a href="http://dev001p.domain.com/" target="_blank">dev001p.domain.com</a> 165.289.178.211 w001-drac 165.289.178.212 w002-drac 165.289.178.213 w003-drac 165.289.178.221 lb001-drac 165.289.178.222 lb002-drac 165.289.178.224 db001-drac 165.289.178.225 db002-drac 165.289.178.226 dev001-drac #eth1 -- this is the cluster 192.168.178.111 w001 <a href="http://w001.domain.com/" target="_blank">w001.domain.com</a> 192.168.178.112 w002 <a href="http://w002.domain.com/" target="_blank">w002.domain.com</a> 192.168.178.113 w003 <a href="http://w003.domain.com/" target="_blank">w003.domain.com</a> 192.168.178.121 lb001 <a href="http://lb001.domain.com/" target="_blank">lb001.domain.com</a> 192.168.178.122 lb002 <a href="http://lb002.domain.com/" target="_blank">lb002.domain.com</a> 192.168.178.124 db001 <a href="http://db001.domain.com/" target="_blank">db001.domain.com</a> 192.168.178.125 db002 <a href="http://db002.domain.com/" target="_blank">db002.domain.com</a> 192.168.178.126 dev001 <a href="http://dev001.domain.com/" target="_blank">dev001.domain.com</a> ######################################################### ##################################/etc/cluster/cluster.conf <?xml version="1.0"?> <cluster alias="cluster1" config_version="1" name="cluster1"> <fence_daemon post_fail_delay="0" post_join_delay="3"/> <clusternodes> <clusternode name="<a href="http://dev001.domain.com/" target="_blank">dev001.domain.com</a>" nodeid="1" votes="1"> <fence><method name="1"> <device name="dev001-drac"/> </method></fence> </clusternode> <clusternode name="<a href="http://w001.domain.com/" target="_blank">w001.domain.com</a>" nodeid="2" votes="1"> <fence><method name="1"> <device name="w001-drac"/> </method></fence> </clusternode> <clusternode name="<a href="http://w002.domain.com/" target="_blank">w002.domain.com</a>" nodeid="3" votes="1"> <fence><method name="1"> <device name="w002-drac"/> </method></fence> </clusternode> <clusternode name="<a href="http://w003.domain.com/" target="_blank">w003.domain.com</a>" nodeid="4" votes="1"> <fence><method name="1"> <device name="w003-drac"/> </method></fence> </clusternode> <clusternode name="<a href="http://lb001.domain.com/" target="_blank">lb001.domain.com</a>" nodeid="5" votes="1"> <fence><method name="1"> <device name="lb001-drac"/> </method></fence> </clusternode> <clusternode name="<a href="http://lb002.domain.com/" target="_blank">lb002.domain.com</a>" nodeid="6" votes="1"> <fence><method name="1"> <device name="lb002-drac"/> </method></fence> </clusternode> <clusternode name="<a href="http://db001.domain.com/" target="_blank">db001.domain.com</a>" nodeid="7" votes="1"> <fence><method name="1"> <device name="db001-drac"/> </method></fence> </clusternode> <clusternode name="<a href="http://db002.domain.com/" target="_blank">db002.domain.com</a>" nodeid="8" votes="1"> <fence><method name="1"> <device name="db002-drac"/> </method></fence> </clusternode> </clusternodes> <cman/> <fencedevices> <fencedevice agent="fence_drac5" ipaddr="165.289.178.211" login="root" name="w001-drac" passwd="pass"/> <fencedevice agent="fence_drac5" ipaddr="165.289.178.212" login="root" name="w002-drac" passwd="pass"/> <fencedevice agent="fence_drac5" ipaddr="165.289.178.213" login="root" name="w003-drac" passwd="pass/> <fencedevice agent="fence_drac5" ipaddr="165.289.178.221" login="root" name="lb001-drac" passwd="pass"/> <fencedevice agent="fence_drac5" ipaddr="165.289.178.222" login="root" name="lb002-drac" passwd="pass"/> <fencedevice agent="fence_drac5" ipaddr="165.289.178.224" login="root" name="db001-drac" passwd="pass/> <fencedevice agent="fence_drac5" ipaddr="165.289.178.225" login="root" name="db002-drac" passwd="pass"/> <fencedevice agent="fence_drac5" ipaddr="165.289.178.226" login="root" name="dev001-drac" passwd="pass"/> </fencedevices> <rm/> </cluster> ########################################################</div>
