nfs warning: mount version older than kernel

['chris']

hi

I cannot mount nfs from Dreambox DM 500-C:

root@dreambox:~> uname -a
Linux dreambox 2.6.9 #1 Sun Apr 8 00:58:35 CEST 2007 ppc unknown
root@dreambox:~>


to the nfs server (DS106j from synology):

storage> uname -a
Linux storage 2.4.22-uc0 #458 Tue Apr 3 01:09:49 CST 2007 ppc unknown


due to the following errors:

root@dreambox:~> mount -t nfs 192.168.200.12:/volume1/box /var/mnt/nfs
mount: Mounting 192.168.200.12:/volume1/box on /var/mnt/nfs failed: Input/outp
ut error

mount: Mounting 192.168.200.12:/volume1/box on /var/mnt/hdd failed: Input/output error


my exports file:

/volume1/box 192.168.200.0/255.255.255.0(rw,sync,no_root_squash)


in /var/log/messages from client I have this error message:

May 31 16:12:34 192.168.200.11 kernel: nfs warning: mount version older than kernel


knows someone howto solve this problem ?

kind regards
chris

to mount nfs from any other linux machine in LAN works perfectly.

on nfs server:

storage> ps aux | grep nfs

maybe I cannot mount because of different kernel or nfs versions ?

[Ivan Ferreira · Accepted solution]

According to this message:

"mount version older than kernel"

I would try to update the util-linux package, the package that contains the "mount" command.

thanks, this problem is solved now.

I've reinstalled nfs-utils
and it seems nfsd was not started:

storage> ps aux | grep nfs
602 root SW [nfsd]
873 root 224 S grep nfs
storage>

I cannot understand how other machines could mount nfs.
