I've just setup a Linux box (running Debian 2.2.20) and have setup Samba
on it to provide file sharing to a few WinXP clients. Normal file
operations (read/write/create/delete/etc.) are all working fine.
However, attempting to create large files (backup drive images,
specifically, each about 4GB) fails - as soon as the file reaches
2147483647 bytes the process fails. Creating the same file locally on
the WinXP box works fine.

The receiving partition on the Linux box has about 130GB free, and is
using the ext2 filesystem. Is ext2 and/or Samba limited to filesizes of
2GB, or have I overlooked something?

Thanks!

Just a quick followup ... the problem also occurs when simply copying a
file >2GB to the server from a WinXP client.

Let me guess - Debian Woody? That kernel is ancient, and probably does
not support files larger than 2 GB. Install one of the 2.4.18-1
packages from security.debian.org.

How big is your hard disk? If it is bigger than 137 GB (the way the
manufacturers count), even with the 2.4.18 kernel, you won't be able to
use the full disk, even with 2.4.18. If your disk is bigger (and
because of that needs LBA48 addressing), install kernel 2.4.19 or
newer. There are up-to-date 2.4 kernel packages available from
backports.org for Debian Woody.

With kernel 2.2.20 indeed the max filesize of ext2 is 2 GB..

(why don't you just use the woody kernel along with etx3 as I asume you
used a Woody image to install?)

Sander & Andreas, thanks for responding ... you're right, it's the
2.2.20 woody install, I went with the latest "stable" build on
debian.org. Definitely an ext2 limit, as I can't even create a >2GB
locally on the box. I'll reinstall a later kernel, probably 2.4.19 as
Andreas suggested - the hard drive is a 160GB partitioned to less than
<130GB partitions now, but that doesn't mean I won't try to jam a 250GB
drive into it somewhere down the line. ;-)

I also saw a few references to Samba having a 2GB filesize limit unless
it's running with 64 bit support (I'm assuming that means 64 bit support
in the code & filesystem, not that it requires a 64 bit processor!) Do
you happen to know if there's an appropriate Samba package available for
2.4.19 that can handle >2GB files?

Thanks for the help ... I'm new to Linux, but so far it's been a blast.
:-)

A 2.4 kernel was available in Woody. I'm not sure that switching to
ext3 would make a difference in the file size limit, or if the 2.2
kernel even supports ext3.

I reinstalled using the 2.4.27 kernel and an ext3 filesystem, and that's
solved the problem, both locally and via Samba.
