NFS problem

NFS problem

[Ralf HECKHAUSEN]

I am booting from an NFS server and have a strange effect. When files are deleted or updated on the server, the board for a whole while still uses the old versions of the files before it notices the update.
What do I have to do to make them more synchronized?

Thanks,
Ralf

I am typing sync permanently on both sides. It shortens the time for the update, but still it is not direct.

Type sync on both your board and your nfs host before accessing the files
on the board.

There is probably a bug somewhere, probably in the NFS server. I am using
Debian 2.1 (slink). I have not bothered to track it down, I just type some
extra syncs.

There is a couple of problems in Linux NFS server. See the Linux NFS
FAQ at http://nfs.sourceforge.net/

[Navin Boppuri]

Hello,

I am trying to boot my custom board with the linux 2.2.13 kernel. It boots
OK but when it tries to do the NFS mount, it fails....... This is how it
looks. I dont understand what's going on. I testing the NFS server with some
other board and same ip's and it works fine. Any ideas????

and it goes on and on. After some time, it says server returned error -5 and
then tries a reboot. What's going on???

        Are you sure you compiled your kernel to use the correct SCC port
for your ethernet interface on the custom board? I have made this mistake
and it produced very simmilar results. Try changing it and see if this fixes it.

Hope this helps,

RE: NFS problem

[t.shantha.laxmi]

This is the problem with the ethernet driver. Make sure you have enabled the
Ethernet Transciever. You need to add code in enet.c to enable the
transciever and set the TENA bit.

Hope this helps,

Re: NFS problem

[Jari]

Hello,
I'm a newcomer. Help me, pls.

Now I want to strip down the size of the library glibc 2.1.3 to make it only
support my application.
Is there anyone teach me about the glibc or where I can have the information
about it.

I've visited Graham Stoney's webpage  at ncbi, and  mmporter's webpage.
I've just built glibc 2.1.3 and I think that I must look into the source code
of it.
But can you tell me the general information about the lib such as what is the
structure of the lib?
what does libc-2.1.3.so support?
what does the other lib support? .. etc..
what is the relationship between them?
is there any web size or any document written about how to reduce the size of
the glibc?

I'm sorry if my question is too simple, because I've just worked with linux for
2 months.
thank in advance.
Jari
