After much dealing with NFS internals, I would recommend NOT using it on
any filesystem where the files are accessed locally.

NFSv2/3 doesn't play nice with anything else which may access the
underlaying disk (including Samba. The only "safe" method is to export
your samba shares from a NFS client elsewhere on the network).

YMMV. NFSv4 is supposedly better behaved. I've not tested it.
