This issue really is not matter of filesystem, but of the architecture. I wrote support for large files in ext2, hopefully it should make it soon into 2.1.9x. Only for 64bit platforms though. If you want to convert all variables in the kernel to long long on 32bit machines, you'd get unbelievably bad performance.
So ext2 has been extended to support large files, only people have to use proper hardware for what they want to do. If you need large files, you probably should think about buying an UltraSPARC or Alpha box, as even if e.g. file limit are increased on 32bit boxes, you'd have problems with mmaping those large files and in several other places as well.
I agree that you _should_ get a fast 64-bit machine if you manage large files, but I think we could use a solution for 32-bit systems too. Novell, NT, and HP-UX can all do it on 32-bit hardware... why can't we?
I thought someone was working on alternate file systems that would get around these limitations even on a 32-bit system....
Thanks, Mark
