I believe that it is actually a limit in the ext2 FS. I don't know if ext3 changes this. The ext2 disk format is quite capable of handling files in the terabyte range. You may be encountering a limit in: - the ext2 driver in your kernel - the general file I/O routines in your kernel - your C library - Samba Samba and NFS(v2) don't like 2GB file sizes. http://www.suse.de/~aj/linux_lfs.html -Mark ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
Re: File sizes
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 At some point hitherto, Mark Komarinski hath spake thusly: Samba and NFS(v2) don't like 2GB file sizes. http://www.suse.de/~aj/linux_lfs.html That page is a bit outdated. It talks about RH 6.2 as being current, and doesn't mention ext3 at all. I happened to be looking at the changelog for Samba the other day for something unrelated, and noticed that recent versions DO have support for large files as of 2.2.1: New option to allow new Windows 2000 large file (64k) streaming read/write options. Needs a 64 bit underlying operating system (for Linux use kernel 2.4 with glibc 2.2 or above). Can improve performance by 10% with Windows 2000 clients. Defaults to off. Not as tested as some other Samba code paths. http://us2.samba.org/samba/whatsnew/samba-2.2.5.html Haven't used this, so don't know how well it works. However, apparently if you're not using Win2k to transfer from, you're still limited to Windows 4GB SMB limit. Your best bet will probably be to remove the disk and mount it in the system you're going to back it up to, and do the copy locally. - -- Derek Martin [EMAIL PROTECTED] - - I prefer mail encrypted with PGP/GPG!

I don't know if ext2 supports big files. I think you need to turn something on in the kernel somewhere too. I was doing this with XFS on my amanda server at MCL and storing files between 3-6GB at the time. XFS is specifically designed to deal with large files (SGI, movie-making, yadda, yadda, yadda) as opposed to ReiserFS which was specifically designed to deal with lots and lots of small files. I'd try out XFS, recompile your kernel, and go from there. It can definitely be done. -- Seeya, Paul -- It may look like I'm just sitting here doing nothing, but I'm really actively waiting for all my problems to go away.
