Set up an Oracle Cluster File System
You want to start your clustering experiences with an Oracle Cluster File System. Here is how. This is an example using SUSE Linux 11.2. As shared storage we use an iscsi storage.
Configure your iscsi initiator, install everything that yast proposes:
Install ocfs2 software
yast -i ocfs2-tools ocfsconsole
Make the cluster services start at boot
establish passwordless login between all nodes.
Start ocfs2console, write the cluster nodes in with their local host names (what the command "hostname" return).
