Hello list,

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 use rsync to backup my server. On this server are acronis-images, some of them > 2 GB. They give me an error: ERROR: home/ldb/Images/laptop.tib failed verification -- update discarded. This image-file is 12GB, and there are more images in this dir, they also are not copied (but this error is the only one). Only images smaller than 2 GB are synced.

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 Boyd Lynn Gerber wrote:

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.

This is the "userspace" nfs server, is there a particular reason why you are not using the kernel nfs server? It will happily handle files of arbitrary size.

You might hit the nail here. I have been looking with yast if there are other nfs-servers, but did not find what you say here. How do I implement kernel nfs server?

Since it's part of the kernel, you already have it installed. You need nfs-server-utils (or similar name) and uninstall the userspace package. Then just set up /etc/exports and start the server with rcnfsserver restart. Should work...

Ok, did that, and it works. Still have to test with big files. Thanks for helping me out.
