Simple. With a distributed FS, all nodes mount from a single DFS. With NFS,
each node would have to mount from each other node. With 16 nodes, that's
what, 240 mounts? Not to mention your data is in 16 different mounts/directory
structures, instead of being in a unified filespace.
Perhaps I'm being overly simplistic, but in this scenario, what would prevent
one from having, on a single file server, /exports/nodes/node[0-15], and then
having each node NFS-mount /exports/nodes from the server? Much simplier than
your example, and all data is available on all machines/nodes.
