I think the 2 GB limit on files is a filesystem limitation, not a block
device limitation, and as LVM is a block device level feature, it should
not impose any limits on file sizes.

As far as I know, RH8 is recent enough to fully support large files
(greater than 2 GB), but maybe you are using some sort of application
not ported still to support large files, or an application on your.

I seem to remember that things like "old" cpio didn't support large
files, check if this is the case with "strace", and look for file
open()'s with flags O_LARGEFILE. From open(2):

       O_LARGEFILE
              On  32-bit  systems  that  support the Large Files System, allow
              files whose sizes cannot be represented in 31 bits to be opened.

Hope it helps.
