Compare binary or data files in different nfs share

Compare binary or data files in different nfs share

[Simon Gao]

Hi,

Not sure if anyone has seen this kind of problem. I have two NFS shares,
one provided by EMC box, one by Gentoo Linux machine (kernel 2.6.15). 
The source directory is on the EMC machine, destination on the Linux
machine. The client machine runs CentOS 4.2 (kernel 2.6.9-22.0.2.ELsmp).


When untar large tarball of many binary and data files (range from 50 MB
to 700 MB) from source to destination, the uncompressed binary files are
different from the ones in source directory if using diff to compare.
What are the possible reasons to cause the difference?

The local filesystem on the Linux nfs server is reiserfs. Exports file
is set to use "sync,wdelay". Client side uses autofs with  
"rw,nosuid,hard,intr,nfsvers=3,udp".

It turns out that it was an issue between raid card and motherboard.
Lower clock speed for PCI-X bus fixed the problem.
