Message-ID: <20130724091856.GA30866@pfmaster> MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Sender: linux-nfs-owner@vger.kernel.org List-ID: Hello all, We've researched this question for quite a while now and nobody here found a solution to the following problem: 1: A Linux computer is NFS client of some other Linux NFS server and has some active mounts and some processes working with files on that NFS server. 2: Now the NFS server becomes unavailable and a system administrator wants to clean up the situation on the NFS client computer without having to reboot this client computer. Is this possible? And if how exactly? Best Regards and many thanks in advance, Peter Funk P.S.: umount -f -l did not work System hangs for a long time in shutdown and shutdown only succeeds without hard reset after reconnecting the NFS server. -- Peter Funk, home: ✉Oldenburger Str.86, D-27777 Ganderkesee mobile:+49-179-640-8878 phone:+49-421-20419-0 office: ArtCom GmbH, ✉Haferwende 2, D-28357 Bremen, Germany
