List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: nfs-bounces@lists.sourceforge.net Errors-To: nfs-bounces@lists.sourceforge.net Hi, on some of our hosts we have the problem, that copying a file onto an NFS share completely blocks the access to this file and even desktop actions (opening new terminal, moving windows etc.) with Gnome and KDE become merely impossible: # cp file /mnt/file a simultaneous `ls -l /mnt` is blocked and finishes only after the copy process has finished. A `strace ls -l /mnt` shows: # strace ls -l /mnt [...] lstat("file", /mnt is mounted without special options. We see this behaviour on these systems FC5, x86_64, kernel 2.6.19-1.2288.fc5 SMP, mount version 'util-linux 2.13-pre7', NIC: Broadcom NetXtreme BCM5752 PCI Express (rev 02), Speed: 1000Mb/s FC5, i686, kernel 2.6.15-1.2054_FC5, mount version 'util-linux 2.13-pre6', NIC: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 74), Speed: 100Mb/s FC6, x86_64, kernel 2.6.20-1.2944.fc6 SMP, mount version 'util-linux 2.13-pre7', NIC: Broadcom NetXtreme BCM5752 PCI Express (rev 02), Speed: 1000Mb/s The problem is less pronounced on FC5, x86_64, kernel 2.6.18-1.2239.fc5 SMP, mount version 'util-linux 2.13-pre7', NIC: Broadcom NetXtreme BCM5752 PCI Express (rev 02) Speed: 1000Mb/s No such problems are experienced on: FC5, x86_64, kernel 2.6.20-1.2307.fc5 SMP, mount version 'util-linux 2.13-pre7', NIC: Broadcom Corporation Unknown device 167a (rev 02), Speed: 1000Mb/s It's not a problem of mount options. Whatever options I use, the problem is the same. Upgrading kernels is not an option, as the x86_64 systems in questions do not run with 2.6.20 kernels at all. Googling around didn't provide any helpful answers. What can I do to track down the problem in more detail or is there perhaps a solution or workaround somewhere in the wild? I've no experiences with making custom kernels, so all other solutions are preferred ;-) Cheers and thanks frank -- Frank Thommen - IT Support Structures - EMBL Heidelberg fthommen@embl.de - +49 6221 387 8353 ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
