Novell LINUX ENTERPRISE SERVER 10 SP2 - INSTALLATION AND ADMINISTRATION Installation Manual page 314

• Initialize, carve, or configure RAIDs (Redundant Array of Independent Disks) on
the SAN disks, as needed, to prepare the devices you plan to use for your OCFS2
volumes. Leave the devices as free space.
We recommend that you store application files and data files on different OCFS2
volumes, but it is only mandatory to do so if your application volumes and data
volumes have different requirements for mounting. For example, the Oracle RAC
database volume requires the datavolume and nointr mounting options, but
the Oracle Home volume should never use these options.
• Make sure that the ocfs2console, and ocfs2-tools packages are installed.
Use YaST or command line methods to install them if they are not. For YaST in-
structions, see Section 14.5, "OCFS2 Packages" (page 295).
14.6.2 Configuring OCFS2 Services
Before you can create OCFS2 volumes, you must configure OCFS2 services. In the
following procedure, you generate the /etc/ocfs2/cluster.conf file, save the
cluster.conf file on all nodes, and create and start the O2CB cluster service (
o2cb).
Follow the procedure in this section for one node in the cluster.
1 Open a terminal window and log in as the root user.
2 If the o2cb cluster service is not already enabled, enter chkconfig --add
3 If the ocfs2 service is not already enabled, enter chkconfig --add ocfs2.
4 Configure the o2cb cluster service driver to load on boot.
