Configure OCFS2 shared storage in Oracle Enterprise Linux 5.9

1. Prepare the environment
1.1. Software Information
Virtual Machine: VirtualBox 4.2
Operating System: Oracle Linux Server release 5.9
OCFS2: ocfs2-2.6.18-348.el5-1.4.10-1.el5.x86_64.rpm
 
1.2. Host Configuration
1.2.1. Hosts file
[Root @ skynode1 ~] # More/etc/hosts
# Do not remove the following line, or various programs
# That require network functionality will fail.
127.0.0.1 localhost
# Skynode1
192.168.1.241 skynode1
Skynode1-vip 192.168.1.242
# Skynode2
192.168.1.245 skynode2
192.168.1.246 skynode2-vip
192.168.1.250 sky-cluster-scan
10.11.11.11 skynode1-priv
10.11.11.12 skynode2-priv
The current host is used in a simulated rac environment. Therefore, we use a private Nic as the communication address of the ocfs2 cluster. Of course, this cannot be done in the production environment, which will bring serious performance pressure to the private Nic. We recommend that you add a separate Nic as the communication Nic of the ocfs2 cluster.
 
1.2.2. Disk Space
Add an independent disk for ocfs2 cluster Testing

 
1.3. Install ocfs2
After the operating system is installed, the ocfs2-tools has been installed by default, You need to manually install ocfs2. Each node that uses the ocfs2 shared file system must be installed.
[Oracle @ skynode1 ~] $ Rpm-qa | grep ocfs
Ocfs2-tools-1.8.0-10.el5
 
Select yum for ocfs2 installation.
[Root @ skynode1 Server] # yum list | grep ocfs2
