References: <20030105001254.GA48290@lewiz.org> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-mobile@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org I seem to recall a 'nomount' option in fstab(5), the manual page that describes the contents of the /etc/fstab ('filesystem table') file. That plus amd(8) should, in theory, get you a relatively stateless NFS connection. Personally, I don't trust amd(8). It's not clear to me that it's any smarter than I am regarding hung NFS file servers. I've had some success using 'umount -f' to forcibly umount NFS filesystems, from the client side, in the past. However, NFS, while stateless in intent, is really not a good infrastructural element for a plug-and-play network. Plugging in is easy; unplugging may require an explicit shutdown to properly deallocate resources.
