A NFS4 export has active clients. The mount is removed from /etc/exports and 'exportfs -r' is run. Clients immediately start getting 'Stale file handle' errors, but the mountpoint is still busy and cannot be unmounted. Killing off nfsd solves the problem, but is undesirable for obvious reasons. On debian linux, kernel version 3.10-2-amd64, with nfs-utils 1.2.8. Thanks, mh -- Martin Hicks P.Eng. | mort@bork.org Bork Consulting Inc. | +1 (613) 266-2296
