Setup GFS2 Cluster Ubuntu

Install GFS package:

#aptitude install gfs-tools cman clvm

Configure GFS cluster: (note: change name= and IPADDR=  )

#vim /etc/cluster/cluster.conf<?xml version=”1.0″?>
<cluster name=”cluster1″ config_version=”3″>

<cman two_node=”1″ expected_votes=”1″/>

<clusternodes>

<clusternode name=”GFS1″ votes=”1″ nodeid=”1″>

<fence>

<method name=”single”>

<device name=”manual” ipaddr=”10.0.0.71″/>

</method>

</fence>

</clusternode>

<clusternode name=”GFS2″ votes=”1″ nodeid=”2″>

<fence>

<method name=”single”>

<device name=”manual” ipaddr=”10.0.0.72″/>

</method>

</fence>

</clusternode>

</clusternodes>

<fence_daemon clean_start=”1″ post_fail_delay=”0″ post_join_delay=”3″/>

<fencedevices>

<fencedevice name=”manual” agent=”fence_manual”/>

</fencedevices>

</cluster>

Change Lock type: (depend on system enviroments)

# vim /etc/lvm/lvm.conf
#locking_type = 1
#locking_dir = “/var/lock/lvm”
#library_dir = “/lib/lvm2″
locking_library = “liblvm2clusterlock.so”
locking_type = 2
library_dir = “/lib/lvm2″

Restart service:

#/etc/init.d/cman restart
#/etc/init.d/clvm restart

Format SAN Disk to GFS:

#mkfs.gfs2 -p lock_dlm -t cluster1:gfs -j 2 /dev/sdb1   ( /dev/sdb1 : SAN DISK)
#fs2_fsck /dev/sdb1

Mount GFS:

#mount -t gfs2 /dev/sdb1 /data

Auto Mount:

#vim /etc/rc.local
sleep 5
mount -t gfs2 /dev/sdb1 /data
