Fleming" To: Subject: 2.4.9-ac1/2/3 allows multiple mounts of NFS filesystem on same mountpoint Date: Thu, 30 Aug 2001 10:32:29 -0700 Organization: LSG, Inc. MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4807.1700 X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4807.1700 Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Accidentally I mounted a filesystem from my server onto my workstation twice. Mount gave me no error.... Both machines are kernel 2.4.9-ac3, both have NFSv3 support, server is using knfsd, mount is version 2.11b. I export /storage on the server, and mount it on /storage on my workstation. When I boot the workstation, it automatically mounts /storage, so everything's fine. If I then issue a "mount /storage" command, I don't get any error. df then reports two identical mounts for /storage. I can continue to multiple mount (tried up to five mounts). Each "umount /storage" takes away the most recent mount, with the last one performing a real unmount. I can't, however, multiple mount any local filesystems (hard disk or CD-ROM based), and don't have anything else handy to try.
