From: Bernardo Innocenti Subject: NFS client bug in 2.6.8-2.6.11 Date: Tue, 08 Mar 2005 05:53:50 +0100 Message-ID: <422D2FDE.2090104@develer.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Cc: Neil Conway , nfs@lists.sourceforge.net To: lkml Sender: linux-kernel-owner@vger.kernel.org List-ID: Hello, This problem was previously described by Neil Conway. All relevant information here: http://lkml.org/lkml/2005/2/10/97 I still see this very same problem on 2.6.11 vanilla and in Fedora/RawHide hernels. It has haunted me for a couple of months on several Fedora clients. Strangely, a Gentoo client isn't affected, but I couldn't investigate further. When the current directory becomes inaccessible, it remains so until I cd somewhere else and then cd back to it. Sometimes I must wait a few seconds before cd succeeds. Here's a sample session: [executing a find / in another shell to trigger the bug] beetle:/pub/linux/distro/fedora-devel# ll ls: .: No such file or directory beetle:/pub/linux/distro/fedora-devel# cd - / beetle:/# cd - bash: cd: /pub/linux/distro/fedora-devel: No such file or directory beetle:/# [...a few seconds later...] beetle:/# cd - /pub/linux/distro/fedora-devel Appears to be a client bug. The problem only happens when there's heavy filesystem activity on other filesystems (local or NFS). NFS mount options: rw,_netdev,rsize=32768,wsize=32768,hard,intr,proto=udp,addr=10.3.3.1 -- // Bernardo Innocenti - Develer S.r.l., R&D dept. \X/ http://www.develer.com/
