I am no expert at all with NFS, but I just checked my working
/etc/exports, and the thing that I can see that is different is the
fsid values.  Your first (root) entry should be fsid=0, and all the
others should be different integer values.  The fsid identifies the
filesystem and has to be different for each entry.  I just have mine
as 0, 1, and 2.
