nfs server not responding

Hi,

I have a strange problem. I have developed a system in which there is a Nios II system and a memory which is connected to Nios 2 system through pio ports. I am using a C program to write data into the memory and then read the contents of the memory and then dunp it in a file on my host PC. The data to be written to the memory is located on a file in my host PC. But when I start reading the file and sending data to the memory, I can send and read 56 datas but then i get the following msg on the sdk shell:

nfs: server 192.168.4.9 not responding, still trying

nfs: server 192.168.4.9 not responding, still trying

nfs: server 192.168.4.9 OK

Can you please suggest what is the problem?

    hi hippo,

    i did tried the option u mentioned it was like this:

    -o nolock rsize=1024,wsize=1024

    does it make any difference to omit the ',' in between nolock and rsize? just wanted to ask as due to weekend I cannot try it till monday...

    I ahd the same problem. Try "proto=tcp," just before the rsize parameter.

    Hi,

    I guess i figured out the solution and the problem too http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif ...

    I added the option &#39;hard&#39; when mounting and even though i still get the msg as before, ie server not responding, but after sometime the program resumes. Earlier the program used to exit.

    I tried the following..

    mount -t nfs 192.168.4.9:/ext_disk/home/sony /mnt/nfs -o nolock,hard,rsize=1024,wsize=1024

    The problem appears to be in the fact that the device I was trying to mount was on a machine running on Solaris and the nfs version was not ver 3. I havent used a linux machine for the same but I am sure I will be able to solve my problem.

    fmcmurra : I guess the "proto=tcp" option is for the case when we use nfs ver 4. Still thanx for your reply.
