# When simply restarting the NFS server, running "exportfs -ua"

# entries listed in xtab to be removed from the kernel export
# tables, and the xtab file is cleared. This effectively shuts
# down all NFS activity, leaving all clients holding stale NFS
# filehandles, /even/ when the NFS server has restarted.
#
# This is what you would want if you were shutting down the NFS
# server for good, or for a long period of time, but not when the
# NFS server will be running again in short order. In this case,
# then "exportfs -r" will reread the xtab, and all the current
# clients will be able to resume NFS activity, /without/ needing
# to umount/(re)mount the filesystem.
