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

[ 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/

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.....
