Creating a Shared Virtual Disk for Live Migration
node:
ip_port = 7777
ip_address = 10.1.1.2 number = 1
name = example2.com cluster = ocfs2
cluster:
node_count = 2 name = ocfs2
12.Review the status of the OCFS2 cluster service: service o2cb status
13.Load the OCFS2 module: service o2cb load
14.Set the OCFS2 service to be online: service o2cb online
15.Configure the OCFS2 service to start automatically when the computer boots: service o2cb configure
16.Start up the OCFS2 service. service o2cb start
17.Format the shared virtual disk from any of the servers in the cluster: mkfs.ocfs2 /dev/sdh1
18.Mount the shared virtual disk from all the servers in the cluster on /OVS/remote: mount /dev/sdh1 /OVS/remote/
19.Change the /etc/fstab file to include the shared virtual disk mounted at boot:
/dev/sdh | /OVS/remote | ocfs2 defaults | 1 0 |
6.1.2 Creating a Shared Virtual Disk Using OCFS2 on SAN
To create a shared virtual disk using OCFS2 on SAN:
1.Review the partitions by checking /proc/partitions: cat /proc/partitions
major minor | #blocks | name | |
8 | 0 | 71687372 | sda |
8 | 1 | 104391 | sda1 |
8 | 2 | 71577607 | sda2 |
253 | 0 | 70516736 | |
253 | 1 | 1048576 | |
Determine the share disk volume you want to use.
2.Create a new directory named /etc/ocfs2 directory: mkdir /etc/ocfs2
