- Mount the filesystem from the server.
- 'cd' a few directories down into the filesystem.
- reboot the server(1)
- on the client 'ls -l'.
(1) A full reboot isn't needed. Just unexport, unmount, remount,
re-export on the server.
alternately, use a non-linux client and cd down into the filesystem
and
ls -l ..
