getting "nfs warning: mount version older than kernel"

[Philippe Froidevaux <philippe.froidevaux@gmail.com>]

Hello,

I have Debian Sarge installed on 4 servers. All installations are
up-to-date (i.e. "apt-get update && apt-get upgrade"is run
frequently).

3 installation works perfectly. One give me repeated warning with :
Nov 25 19:49:26 localhost kernel: nfs warning: mount version older than kernel
Nov 25 19:54:44 localhost kernel: nfs warning: mount version older than kernel
Nov 25 20:37:23 localhost kernel: nfs warning: mount version older than kernel
Nov 25 20:53:42 localhost kernel: nfs warning: mount version older than kernel
Nov 25 20:54:34 localhost kernel: nfs warning: mount version older than kernel
Nov 25 21:27:24 localhost kernel: nfs warning: mount version older than kernel
Nov 26 08:21:33 localhost kernel: nfs warning: mount version older than kernel

I don't understand why. All 4 installations have exactly the same
packages and kernel versions and the same configuration. Versions used
are :

diuflx07:~# dpkg -l | grep mount
ii  autofs         4.1.3-4        A kernel-based automounter for Linux
ii  mount          2.12-10        Tools for mounting and manipulating filesyst
diuflx07:~# dpkg -l | grep nfs
ii  nfs-common     1.0.6-3        NFS support files common to client and serve
diuflx07:~# uname -a
Linux diuflx07 2.6.8-1-686-smp #1 SMP Thu Nov 11 11:49:00 EST 2004
i686 GNU/Linux

can anyone help here ?


Thanks,

Philippe.
