I agree; OCFS2 is unappreciated, and it is quite a good filesystem. However, it does have it's limitations. We use OCFS2 for backup volumes on our fibre channel SAN storage. We've found it performs adequately enough, although filesystem performance can slow down when you have a lot of sequential writes going to the storage. It does some things really well, but in the end it has a single point of failure - the storage array or server hosting the storage becomes a bottleneck and SPOF. It doesn't take the place of newer clustering technologies that spread data around multiple points of failure.
