For what I know each filesystem usually implies a limit of the files size, for the current specification of ext2/3 filesystem, the limit is probably over the terabyte, then the implementation in the kernel may also imply a limit, Linux version 2.2.x had a limit around 2GB, if I still don't make any mistake. Last the compilation options used to build dar (check largefile sypport with `dar -V' ) affect the way file are handled. I don't know the ReiserFS,thus I can't tell you what the maximum size it can handle, nor I can speak about its implementation in the Linux kernel. Just a trick, if you cannot have as larger files as you want, you still may use slice size which are an exact divisor of the destination storage. Suppose you want to save you data over DVD-R of, let's say, 11 GB each, but cannot overcome the 2GB limit for any reason, you can choose a slice size of 1GB, this will allow you to put 11 slices per DVD-R, and thus fullfil each DVD-R.

What exactly is limiting the filesize? Is it the filesystem (ReiserFS) or something else? Is there an easy way to allow larger files? > > Thanks for your reply, I have download the pre-release and found a lot of documentation that I hadn't seen yet. > > Tristan > > >>>>Denis Corbin <[email protected]> 10/21/03 12:00PM >>> >>> > Hello, > > I don't think it would be a good reasons to limit the slice size.
