This can be done with 'kill' or 'rpc.nfsd 0' or echo 0 > /proc/fs/nfsd/threads kill mountd killall rpc.mountd kill idmapd unexport everything. This can be done with 'exportfs -f' and checked by grep . /proc/net/rpc/*/content this should only contain comments unmount the 'nfsd' filesystem umount /proc/fs/nfsd rmmod nfsd (it look me ages to remember idmapd - but lsof /proc/net/rpc/*/* gave it away) NeilBrown -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
