Try turning off root_squash in your /etc/exports file...
Default NFS server behavior is to prevent root on client machines from
having privileged access to exported files. Servers do this by mapping the
"root" user to some unprivileged user (usually the user "nobody") on the
server side. This is known as *root squashing.*
One way to test, can you add files/dirs as a non root user?

Did you know that it costs forty thousand dollars a year to house each
prisoner?...I don't think we should give free room and board to criminals. I
think they should have to run twelve hours a day on a treadmill and generate
electricity. And if they don't want to run, they can rest in the chair
that's hooked up to the generator.
