OCFS2 cluster – quick setup guide
OCFS2 is a POSIX-compliant shared-disk cluster file system for Linux capable of providing both high performance and high availability. Cluster-aware applications can make use of parallel I/O for higher performance. OCFS2 is mostly used to host Oracle Real application clusters (RAC) database on Linux clusters.
The below steps shows how to create ocfs2 filesystem on top a multipath’d SAN lun and mount it on Linux clusters.
1. Identify the nodes that will be part of your cluster.
2. Export/Zone the LUNs on the SAN end and check whether they are accessible on all the hosts of the cluster. (fdisk -l or multipath -ll)
3. If you need multipathing, configure multipath and the multipathing policy based on your requirement. For Linux multipath setup, refer Redhat’s multipath guide.
4. Create OCFS2 configuration file (/etc/ocfs2/cluster.conf) on all the cluster nodes.
