I think that the default vrsion of 9.2 is nfs 2.0. If I am correct, there is a limitation of 2. Gbyte because the NFS 2.0. In nfs 3.0, this limitation has been increased in size.

I seem to be having some problems with 10.0 with an AMD 64. That version of nfs would lock the system up if you try to mount server. I had to use the user space version to prevent that.

Under 10.0 this problem goes away. In the current version, I am still trying to hunt the problem down I found that the system would freeze given the following:

copy Nsf server-64-bit nfs client-32-bit
from nfs server server system lock up
from cp nfsclient-32-bit server system lock up
neither file was in exported file system
sftp seems to work from nfsclient

Found out that my backupserver does not store big files through nfs.
Suse9.2 with nfs-server installed, is mounted on another 9.2 system. This
is my server, where harddisk images are put with acronis.

Mount options: rsize=8192,wsize=8192,auto,rw

Is it possible to get this version of nfs-server (2.2beta51-208) to accept
big files? Or do I have to install something different?
How did you test this? nfs shouldn't have a problem with big files. In most cases, the problem is with the tools trying to write (or read) the file

I have this exact same problem. It is at 4 GB or close to it. I have tried cp, dd, scp, ftp, ... These same commands work when on the machine but any files larger than this also do not show up properly on NFS. I get this message from the commands.


scp: /home/mount/uw714/top/zenez/zen/iso/suse/suse9.3dvd.iso: Value too large for defined data type

ftp /home/mount/uw714/top/zenez/zen/iso/suse/suse9.3dvd.iso: Value too large for defined data type

cp
/home/mount/uw714/top/zenez/zen/iso/suse/suse9.3dvd.iso: Value too large for defined data type

dd
/home/mount/uw714/top/zenez/zen/iso/suse/suse9.3dvd.iso: Value too large for defined data type

So I do not know what to do to get the large file copied to a NFS mounted share.
