Another respondent already mentioned "umount -f ..." I wanted to clear up something you may, or may not, know about NFS and that is that there isn't really a connection. Unless the behaviour changed in FBSD 7, when mounting NFS; UDP is used. UDP is a connectionless protocol in the IP suite of protocols. Because of this, detecting a lost "connection" is rather problematic. Usually, timeouts are used when sending new information, or requesting something from the server. I'd read through the mount_nfs(8) manual page just to be sure of options that may help out in this case. The -c -t -D and some others looked rather promising. In my experience, it's usually pretty difficult to unmount an unresponsive NFS mount. In fact, *and only because of the environment in which I was working*, I usually ended up rebooting my box. This is because I didn't want to wait for the timeouts (painfully slow in some default configurations; upwards of 10 minutes or more). This probably isn't feasible if your system hosts services for other clients.
