I'm developing a moderate sized ramdisk image to be used on an embedded
project, and I'm having trouble getting all of the NFS client-side file
dependencies sorted out on the ramdisk. I'm using YDL installed on
powermacs for my hosts & servers (not cross-hosted from x86 boxes). The
NFS mounts work fine when mounted from another powermac or when the
embedded system is Root-On-NFS booted (both of which have a full YDL
install).
The problem is that when the embedded system is booted to ramdisk, and
then an NFS mount of the server is attempted; the mount command goes
away, and eventually a "portmap: server localhost not responding, timed
out" message pops up. The NFS server box is listed in the /etc/hosts
file.
My ramdisk image has been built by taking various components from a YDL
install; this is so that the target embedded environment (ramdisk) has
compatibility with customer's lab machines (typically YDL boxes). It's
my opinion that I have missed something on the client-side when
assembling the ramdisk image. Does anyone know where I can find a
listing of the dependencies within the various NFS client components
(mount, nfs, rpc, libs, etc)? Thanks, everyone.

HI! all
I am developing a MPC8245 board .because lacking money I cann't afford to buy the commercial bootloader for my custom-built board,so I have downloaded the CSB_umon source (http://www.cogcomp.com/csb_umon_10_5_2002.zip) for the CS821 board( It uses the MPC8245 as his main processor).Compare to his father umon(micro monitor) source downloaded from the lucent, there no /common/CPU directory.is anyon who is the the Cogent Computer Systems' customer can share it too me?
Thanks a lot for your cooperation.
Best regards
chete

Jim,
It sounds like its trying to use portmap for locking purposes. Try
using a -o nolock argument to your mount call, as it sounds like you
don't have the port mapper installed or running on your ram disk.
This is what we had to do with ours, and it works great.
Here's what we do:
mount -t nfs -o nolock $SERVER:/home/log /log
Hope this helps..
Paul
