    nfs warning: mount version older than kernel


    hi

    I cannot mount nfs from Dreambox DM 500-C:
    Code:
    root@dreambox:~> uname -a
    Linux dreambox 2.6.9 #1 Sun Apr 8 00:58:35 CEST 2007 ppc unknown
    root@dreambox:~>
    to nfs server (DS106j from synology):
    Code:
    storage> uname -a
    Linux storage 2.4.22-uc0 #458 Tue Apr 3 01:09:49 CST 2007 ppc unknown
    due to these errors:
    Code:

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

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

    on nfs server:
    Code:

    Code:

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

    knows someone howto solve this problem ?

    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.
