This requires shared storage, either presented via Fibre Channel or iSCSI. In your setup, the local disks are not shared between the nodes, therefore there is no need to use OCFS2 on those nodes. If you want to share the local storage of Node 1 and Node 2 to Node 3, just use NFS. If you actually need proper shared/clustered storage, you'll have to turn one of those machines into a filer, present the disks as iSCSI LUNs to the other two machines and then use OCFS2 to allow both of the other two machines to mount the iSCSI LUN at the same time.
I am new to OCFS and had a question on what I can expect from OCFS2.
