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

[Matthias Fuchs <matthias.fuchs@esd-electronics.com>]

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 ?
