Any program that wants to use files larger than 2 GB has to have the modern glibc (should be fine with RHL 8) and needs to have large file support compiled in. Usually this means that the open() syscall has to use the O_LARGEFILE flag when opening files.
You can determine if a program is using O_LARGEFILE with the "strace"
utility that watches syscalls.
For example, run "strace cp foo bar", or filter its output like this:
strace cp foo bar 2>&1|grep foo
That will show you only the lines where it's actually trying to operate
on "foo". On my system, the last line of output looks like this:
open("foo", O_RDONLY|O_LARGEFILE) = 3
This means that cp is opening the file with O_LARGEFILE and therefore
supports file greater than 2GB.
Hope this helps,
Jeremy
