Hello, I have a startup issue with a cluster that we've set up. We have 34 HP G7 servers running in a cluster to share one SAN resource, a HP (Lefthand) P4500. All the servers are running RHEL 5.4. When we reboot the cluster, a small, random number of nodes will not mount the SAN. On inspection, the failing nodes are members of the cluster (looking at clustat). When I run a "service cman status" on them, they say that groupd is not running. I'm assuming that because of this, clvmd does not run correctly (I see a "clvmd: Can't open cluster manager socket: No such file or directory" in the messages log), so no SAN VG and no SAN mount. If I do a "service cman restart; service clvmd restart; mount -a" the SAN will mount correctly. I've created a sample cluster.conf below. It only contains 4 nodes, but it is identical to the 34 node system. We use IPMI for the fencing, as the HP G7 systems are iLO3, and we could not get fence_ilo to work with them. Any help is appreciated - thanks! --pete <?xml version="1.0" ?> <cluster config_version="1" name="dasCluster"> <fence_daemon post_fail_delay="0" post_join_delay="6"/> <totem consensus="45000" join="15000" send_join="1000" token="60000" token_retransmits_before_loss_const="100"/> <logging to_stderr="yes"> <logger debug="on" ident="CPG" to_stderr="yes"/> <logger debug="on" ident="CMAN" to_stderr="yes"/> </logging> <clusternodes> <clusternode name="g2das01x" nodeid="1" votes="1"> <fence> <method name="1"> <device name="das01"/> </method> </fence> </clusternode> <clusternode name="g2das02x" nodeid="2" votes="1"> <fence> <method name="1"> <device name="das02"/> </method> </fence> </clusternode> <clusternode name="g2das03x" nodeid="3" votes="1"> <fence> <method name="1"> <device name="das03"/> </method> </fence> </clusternode> <clusternode name="g2das04x" nodeid="4" votes="1"> <fence> <method name="1"> <device name="das04"/> </method> </fence> </clusternode> </clusternodes> <cman cluster_id="881991"/> <fencedevices> <fencedevice action="reboot" agent="fence_ipmilan" auth="password" ipaddr="g2das01x-ilo" lanplus="1" login="admin" name="das01" passwd="b"/> <fencedevice action="reboot" agent="fence_ipmilan" auth="password" ipaddr="g2das02x-ilo" lanplus="1" login="admin" name="das02" passwd="c"/> <fencedevice action="reboot" agent="fence_ipmilan" auth="password" ipaddr="g2das03x-ilo" lanplus="1" login="admin" name="das03" passwd="d"/> <fencedevice action="reboot" agent="fence_ipmilan" auth="password" ipaddr="g2das04x-ilo" lanplus="1" login="admin" name="das04" passwd="e"/> </fencedevices> <rm> <failoverdomains/> <resources/> </rm> </cluster> -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
