Hi*, I have tried to set up this configfile here: <clusternode name="box1" nodeid="1" votes="1"> <multicast addr="224.0.0.1" interface="eth0"/> <fence> <method name="1"> <device name="box1_IPMI"/> </method> <method name="2"> <device name="manual" nodename="box1"/> </method> </fence> </clusternode> <clusternode name="box2" nodeid="2" votes="1"> <multicast addr="224.0.0.1" interface="eth0"/> <fence> <method name="1"> <device name="box2_IPMI"/> </method> <method name="2"> <device name="manual" nodename="box2"/> </method> </fence> </clusternode> <clusternode name="box3" nodeid="3" votes="1"> <multicast addr="224.0.0.1" interface="eth0"/> <fence> <method name="1"> <device name="box3_IPMI"/> </method> <method name="2"> <device name="manual" nodename="box3"/> </method> </fence> </clusternode> <clusternode name="box4" nodeid="4" votes="1"> <multicast addr="224.0.0.1" interface="eth0"/> <fence> <method name="1"> <device name="box4_IPMI"/> </method> <method name="2"> <device name="manual" nodename="box4"/> </method> </fence> </clusternode> </clusternodes> <fencedevices> <fencedevice agent="fence_ipmilan" auth="none" ipaddr="10.0.0.2" login="power" name="box1_IPMI" passwd="powerpower"/> <fencedevice agent="fence_ipmilan" auth="none" ipaddr="10.0.0.3" login="power" name="box2_IPMI" passwd="powerpower"/> <fencedevice agent="fence_ipmilan" auth="none" ipaddr="10.0.0.4" login="power" name="box3_IPMI" passwd="powerpower"/> <fencedevice agent="fence_ipmilan" auth="none" ipaddr="10.0.0.5" login="power" name="box4_IPMI" passwd="powerpower"/> <fencedevice agent="fence_manual" name="manual"/> </fencedevices> <rm> <failoverdomains/> <resources> <ip address="192.168.50.6" monitor_link="1"/> </resources> </rm> </cluster> The cluster is coming up without errors. But when I shutdown the network on one node nothing happens. The only message I get is dlm: closing connection to node 4 On node 2 and 3. Any suggestions? Is there a timeout I have to wait for? Why I can not ping my cluster address 192.168.50.6???? -----Original Message----- From: linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of brad@xxxxxxxxxxxxxx Sent: Montag, 13.
