Big file support in Linux 2.2

Big file support in Linux 2.2

[jpranevich]

Hello,

For one of our projects here, we've crashed head first into the 2 gig file size
limitation in Linux 2.2 kernels. While I know that this has been solved in
2.3/2.4, has there been any work to backport this feature into a Linux 2.2
kernel? I'm looking for a temporary solution until we can move to Linux 2.4
directly, but obviously not until after it's been "really" released. :)

Yes, I know this is likely to be relatively unstable. (Probably almost as
unstable as running a 2.4-pre kernel in production), but at least it would give
us a start.

Thanks for your help,

Joe

You can get a 2.2 LFS patch from:
http://www.scyld.com/software/lfs.html

There may be other sources.  You also need to have a newer glibc (or recompile
your own) to really support LFS.

Cheers, Andreas

However all software is *not* written to use LFS extended versions
of things.  Often using defines of:

        -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64

in the Makefile of said software CFLAGS is enough, but that may
still sometimes not be enough.  Specifically if the system will
then use some libraries which are not LFS compatible.

Seek for LFS on Freshmeat. Requires a kernel patch, and a glibc
recompile. I'm still having some problems with it, mainly cp -ar giving
some wonderful weard strace results.
