Creating a Shared Virtual Disk for Live Migration

Oracle VM Server User’s Guide

Create the OCSF2 configuration file as /etc/ocfs2/cluster.conf. The following is a 
sample cluster.conf file:

node:

        ip_port = 7777

        ip_address = 10.1.1.1

        number = 0

        name = example1.com

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 10.1.1.2

        number = 1

        name = example2.com

        cluster = ocfs2

cluster:

        node_count = 2

        name = ocfs2

Review the status of the OCFS2 cluster service:

service o2cb status

Load the OCFS2 module:

service o2cb load

Set the OCFS2 service to be online:

service o2cb online

Configure the OCFS2 service to start automatically when the computer boots:

service o2cb configure

Start up the OCFS2 service.

service o2cb start

Format the shared virtual disk from any of the servers in the cluster:

mkfs.ocfs2 /dev/sdh1

Mount the shared virtual disk from all the servers in the cluster on /OVS/remote:

mount /dev/sdh1 /OVS/remote/ -t ocfs2

Change the /etc/fstab file to include the shared virtual disk mounted at boot:

/dev/sdh               /OVS/remote              ocfs2   defaults        1 0

To add a shared virtual disk using NFS:

Find an NFS mount point to use. This example uses the mount point:

mycomputer:/vol/vol1/data/ovs

Add the following entry to the /etc/fstab file:

myfileserver:/vol/vol1/data/ovs /OVS/remote  nfs 

rw,bg,intr,hard,timeo=600,wsize=32768,rsize=32768,nfsvers=3,tcp 0 0
