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
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.
2 If the o2cb cluster service is not already enabled, enter
