There are comparisons on the web, but in short, cluster size, GFS can be a major pain in the ass for some people to set up (fencing support is usually said pain), and GFS has distribution support. For such a small installation, you are probably better off with OCFS2. If you need something that is almost exactly the same as a local filesystem and depend upon certain filesystem behaviors for whatever reason (locking comes to mind), you will be better off with GFS.
