Does it work, though? Without Oracle admin tools?

Hey, any test you wanna run is fine with us. I'm pretty sure that OCFS
belongs to Oracle, though, patent & copyright, so we couldn't actually use it
in practice.
If your intention in this test is to show the superiority of raw devices, let
me give you a reality check: barring some major corporate backing getting
involved, we can't possibly implement our own PG-FS for database support. We
already have a TODO list which is far too long for our developer pool, and
implementing a custom FS either takes a large team (OCFS) or several years of
development (Reiser).
Now, if you know somebody who might pay for one, then great ....
