It then points to http://wiki.linux-nfs.org/wiki/index.php/PNFS_server_projects. But, as far as spNFS is concerned, the two wiki pages form a circular reference. The other options for file layout are no go either.

My impression is that the most likely to work possibilities are either
the exofs-based or gfs2-based servers.  Boaz Harosh might be able to
help with the latter.  I don't know if the wiki instructions are up to
date.  You probably need to build a kernel from Benny's git tree in
either case.
