Question Could Large file Size cause "RPC: Authentication error" with NFS server mount


Hello,

I think I am having a problem due to an NFS server file size limit. Is it possible I am missing a parameter on the RHEL NFS setup to handle large files?

BACKGROUND:

I am running an NFS server on a RHEL 5.1 machine and the HP-UX 11.0 machine does an NFS mount to that file system. The HP-UX executes a program that resides on the HP-UX machine to process a large 35 GB data file that resides on the NFS server machine. The program on the HP-UX can only read/process the first portion of the file untill an "RPC: Authentication error" is returned multiple times until the program prematurely decides that it has reached the end of file.

I tried recompiling the same program to run on the RHEL 5.1 NFS server to access the 35 GB file locally (on the NFS server instead on HP-UX) and the program completed successfully, processing the whole file (about 7 hours of processing) with no "RPC: Authentication error." In addition, I have been running the nfs mount with the same machines for quite some time, but not with such large files sizes.

Thank you,

-WP

Take a look at this link, it's a little dated, but NFS does not move very fast, so likely to be relevant to your situation. :http://forums11.itrc.hp.com/service/...threadId=72952 It seems to me that file size is an issue for NFS, but a more likely candidate is some version of a program like tar or cp or something on the Unix box? Is there a script being used to operate on your file? Can you post it?

irishbitte, Thank you for your post. It appears that the problem may have been due to other activity on the network. I found out that people were rebooting systems on the network during the same time of this error.

Thank you,

Aha! Didn't realise you had it mounted from other machines, I gotcha now!
