What you need to investigate is GFS. It is a complete serverless file
system. It is released on GPL. But unfortunately it is pretty much alpha
and lacks some rather fundamental functionality on Linux. Frankly they
could probably use some more development help, it would be nice to see it
become robust, cause I think the concept of a shared filesystem is a Good
Thing (tm).
