Hi, I want to setup a two node cluster using cman. here are the steps I followed ========================================= Cluster nodes: node1 & node2 ========================================= [root@node1 ~]# cman_tool status Version: 6.1.0 Config Version: 5 Cluster Name: k7 Cluster Id: 269 Cluster Member: Yes Cluster Generation: 48 Membership state: Cluster-Member Nodes: 2 Expected votes: 1 Total votes: 2 Quorum: 1 Active subsystems: 8 Flags: 2node Dirty Ports Bound: 0 11 Node name: node1 Node ID: 2 Multicast addresses: 239.192.1.14 Node addresses: 10.10.10.40 [root@node2 ~]# cman_tool status Version: 6.1.0 Config Version: 5 Cluster Name: k7 Cluster Id: 269 Cluster Member: Yes Cluster Generation: 48 Membership state: Cluster-Member Nodes: 2 Expected votes: 1 Total votes: 2 Quorum: 1 Active subsystems: 8 Flags: 2node Dirty Ports Bound: 0 11 Node name: node2 Node ID: 1 Multicast addresses: 239.192.1.14 Node addresses: 10.10.10.39 ========================================= Logical volumes on node node1 ========================================= /dev/vg1/lvol0 formatted as GFS [root@node1 ~]#gfs_mkfs -p lock-dlm -t k7:CLVM0 -j 2 /dev/vg1/lvol0 [root@node1 ~]#mkfs -t gfs -p lock-dlm -t k7:CLVM0 -j 2 /dev/vg1/lvol0 ========================================= Procedures on node node1 ========================================= [root@node1 ~]# service cman start Starting cluster: Enabling workaround for Xend bridged networking... done Loading modules... done Mounting configfs... done Starting ccsd... done Starting cman... done Starting daemons... done Starting fencing... done [ OK ] [root@node1 ~]# service clvmd start Starting clvmd: [ OK ] Activating VGs: 1 logical volume(s) in volume group "vg1" now active Error locking on node node2: Command timed out [ OK ] [root@node1 ~]# gnbd_serv -n gnbd_serv: startup succeeded [root@node1 ~]# gnbd_export -c -e gnbd1 -d /dev/vg1/lvol0 gnbd_export: created GNBD gnbd1 serving file /dev/vg1/lvol0 [root@node1 ~]# mount /dev/vg1/lvol0 /mnt/gfs_local/ [root@node1 ~]# cd /mnt/gfs_local/ [root@node1 gfs_local]# ls fence.css mantisbt-1.1.6.tar.gz vkarmalicense.lic JMeter.pdf mysql-cheat-sheet-v1.pdf [root@node1 gfs_local]# ========================================= Procedures on node node2 ========================================= [root@node2 ~]# service cman start Starting cluster: Enabling workaround for Xend bridged networking... done Loading modules... done Mounting configfs... done Starting ccsd... done Starting cman... done Starting daemons... done Starting fencing... done [ OK ] [root@node2 ~]# service clvmd start Starting clvmd: [ OK ] [root@node2 ~]# gnbd_serv -n gnbd_serv: startup succeeded [root@node2 ~]# gnbd_import -i 10.10.10.40 [root@node2 ~]# mount /dev/gnbd/gnbd1 -o lockproto=lock_dlm /mnt/gfs_gnbd/ [root@node2 ~]# cd /mnt/gfs_gnbd/ [root@node2 gfs_gnbd]# ls fence.css mantisbt-1.1.6.tar.gz vkarmalicense.lic JMeter.pdf mysql-cheat-sheet-v1.pdf My /etc/cluster/cluster.conf is <?xml version="1.0"?> <cluster config_version="5" name="k7"> <fence_daemon post_fail_delay="0" post_join_delay="3"/> <clusternodes> <clusternode name="node2" nodeid="1" votes="1"> <fence/> </clusternode> <clusternode name="node1" nodeid="2" votes="1"> <fence/> </clusternode> </clusternodes> <cman expected_votes="1" two_node="1"/> <fencedevices/> <rm> <failoverdomains> <failoverdomain name="node2" ordered="0" restricted="0"> <failoverdomainnode name="node1" priority="1"/> </failoverdomain> <failoverdomain name="node1"> <failoverdomainnode name="node2" priority="1"/> </failoverdomain> </failoverdomains> <resources/> </rm> </cluster> Why do the message "Error locking on node node2: Command timed out" pops up every time ? Can a cluster be created without specifying fencing and all that stuff ? I just wanted to use GFS over a clustered environment.....
