13.2 Creating an OCFS2 Volume
Follow the procedures in this section to configure your system to use OCFS2 and to
create OCFS2 volumes.
13.2.1 Prerequisites
Before you begin, do the following:
• Initialize, carve, or configure RAIDs 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 13.1.6, “OCFS2 Packages” (page 273).
13.2.2 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 or equivalent.

o2cb
cluster service is not already enabled, enter
