Re: mount via nfs using MontaVista's Linux for IBM405

Hello Frank,

I tried the nolock option for the mount command. It does not really
work, only sometimes, not very
frequently.

Here is exactly how I do the mount:

mount -t nfs -o nolock -v 192.168.2.190:/home/matthias/canbtgw
/home/matthias

(All directories exist, mounting from other computers is working.)

Here is the output:

  nfs warning: mount version older than kernel
  192.168.2.190:/home/matthias/canbtgw on /home/matthias type nfs
(rw,nolock,addr=192.168.2.190)
... long time later ...
  VFS: Close: file count is 0
  VFS: Close: file count is 0
... long time later ...
  VFS: Close: file count is 0

... mount never returns ...

Any further idea ?

Sorry, I didn't go back to the old target root file system to test
the "-o nolock".  You need to use a newer version of mount to solve this
problem (and continue to specify -o nolock).  When your Walnut CDK arrives
your problem will be resolved because it contains the newer mount.

Hello,

I am trying to mount a directory from a nfs server to my IBM405GP board.

Here are the facts:

        Kernel on our 405 board: 2.4.0-test2_mvista_001126
        Root filesystem: target_ftest4 from MontaVista

When I do a: mount -t nfs <nfs-servers-ip>:/home/matthias /test on the
405 board, I get this output (after some delay):

        nfs warning: mount version older than kernel
        portmap: server localhost not responding, timed out
        portmap: server localhost not responding, timed out
        lockd_up: makesock failed, error=-5

But I can still telnet to the board (it does not crash) but I cannot
interrupt the mount call.

The nfs server is working properly, because I get the root filesystem
from the same server (with no problems).

Has anybody a solution for this problem ?

Add the "-o nolock" option to the mount command.
