This is absolutely *not* required. RHEL4 (and thus CentOS-4) explicitly support devices and filesystems up to 8TiB. As I mentioned before, however, one must use gpt disklabels on any device larger than 2TiB. And this precludes one from booting from such a large device, as neither grub nor lilo understand gpt disk labels. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
