Sun's ZFS?  I don't think that's distributed, is it?  Does it provide a 
single namespace across an arbitrarily large cluster?  From the 
documentation I can find it just sounds like a better single-node 
filesystem.  It'd be good for, e.g., mounting 40 1TB drives on a big Sun 
box, but I don't see how it's meant to, e.g., stitch together 4,000 
drives across a cluster of 1,000 nodes into a single filesystem.

There is also a distributed filesystem called zFS from IBM Haifa:


But that's a research project.
