In such situations, >/etc/umount refuses to unmount the file system in question. One Probably unmount(2) fails with an EBUSY error. This means there is at least one process which is trying to do IO on the NFS file system. You have to kill this process first, although it probably won't listen to a kill signal unless you have mounted the file system with the 'intr' option. These processes show up with ps(1) as (swapped out) processes in disc wait. -- Ronald van der Pol
