I have a file server that exports as NFS. On an Ubuntu machine I mount that, then try to export it as an NFS volume. When I go to export it, I get the message:

exportfs: /test/nfs-mount-point does not support NFS export

How can I get this to work, or at least get more information as to what the problem is?

Exact steps:

Unbuntu 12.04

mount -f nfs myfileserver.com:/server-dir /test/nfs-mount-point

[Works fine, I can read & write files]

/etc/exports contains:

/test/nfs-mount-point *(rw,no_subtree_check)

sudo /etc/init.d/nfs-kernel-server restart
