[opensuse] Max filesize on NFS? 4G?
I was just surprised by hitting a 4GB file limit on NFS -- am running Suse 10.2 on client (currently running SuSE2.6.18.2-34-bigsmp), and SuSE 9.3 (with vanilla 2.6.20) on server. The target file system (xfs) supports large files. I was running an "xfsdump" |bzip2>remotefile I'm surprised to be hit by the small file limit on NFS. Is there some specific parameter I need to support large files? The same command, run locally on the server, runs "fine" (>4GB ok), so it definitely seems to be a NFS related problem. Ideas? Help?

4 GB is the limit of a 32bit processor. Mike -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Basically, NFS on x86 arch has this limit ? How about NFS on x86-64 arch ? Most software for x86 has no this limitation - look at ext3. -Alexey -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Not really. 4 x 2^32 is the limit of a 32-bit word (unsigned). Every x86 processor produced in the past ... 10? 15? 20? years can perform 64-bit arithmetic.

Duh... 2^32 is the limit of an unsigned 32-bit word, of course. 2^30 is a "binary billion", and four of those are 4 gigs. RRS -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Guys, The file size depends on the file system where it resides not of the CPU. Of course up to a degree. I remember from my os/2 days creating tar files of the whole system, I could do it in a JFS formatted partition but not in a fat because of size limitations. -=terry(Denver)=- On Mon, 2007-03-12 at 22:31 -0700, Randall R Schulz wrote:

That's absurd. I'm using a 32 bit processor and I have files of 9 gigas, so having large files is not an intrinsic processor limitation. Actually, if you look at the opensuse manual, «Table 17.2. Maximum Sizes of File Systems (On-Disk Format)» http://localhost/usr/share/doc/manual/opensuse-manual_en/manual/sec.filesyst... shows the large file support limits for NFS: File System File Size (Bytes) File System Size (Bytes) - --------------------+-------------------+---------------------------- NFSv2 (client side) 2^31 (2 GiB) 2^63 (8 EiB) NFSv3 (client side) 2^63 (8 EiB) 2^63 (8 EiB) The kernel limit for 32 bit processors is 2TiB (2^41 bytes). So, 4GiB is very far from the limit. Either there is some parameter needed somewhere, or there is a bug. - -- Cheers, Carlos E.

Looks more like she may be using NFSv2. Try NFSv3 instead. You specify it as a mount option. -- Geir A. Myrestrand -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
