nfs warning: mount version older than kernel

cccc · 05-31-2007, 11:49 AM

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:

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

root@dreambox:~> mount -t nfs 192.168.200.12:/volume1/box /hdd
mount: Mounting 192.168.200.12:/volume1/box on /hdd failed: Input/output error

root@dreambox:~> mount -t nfs -o rw,nolock 192.168.200.12:/volume1/box /var/mnt/
nfs

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

my exports file:

Code:

/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:

Code:

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

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

on nfs server:

Code:

Code:

storage> ps aux | grep nfs

Code:

  890 root        224 S   grep nfs

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

knows someone howto solve this problem ?

kind regards

mount -t nfs -o rw,nolock 192.168.200.12://volume1/box /var/mnt/

thanks, but still doesn't work.

I've got these "mount version older than kernel" warnings occasionally in the past, it never denied me to mount NFS volumes. I think your problem lies elsewhere. Any firewalls active?

cccc · 05-31-2007, 02:27 PM

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.

Now that it's solved for you, maybe you could help me. I've just bought a network harddisk (Western Digital) and I can't mount it from my Dreambox and there some kind of linux installed on it. Unlike you I'm not familiar with linux. How do I reinstall nfs-utils on my dreambox? I typed "ps aux | grep nfs" on my Dreambox and there were no nfsd present. Or is it my network drive missing it?

I can mount to my laptop (Windows) with CIFS through the webinterface, I've tried with nfs, but it didn't work, I hope it's because I have problems with the nfsd (what ever that is).

I'm really lost right now

what's the exact name of box with extenal harddisk ?
could you get command line via telnet or ssh ?
what kind of linux is it installed on it ?

Code:

# uname -a

is it nfs server running on box ?

Code:

ps aux | grep nfs

otherwise will be very difficult to be clairvoyant.

greetings
