Thanks to all the replies... Very interesting stuff... However I'm still trying to understand how to have a hardware RAID 5 (4x 1TB disk) system and load CentOS on it. I'm looking for the UEFI bios but don't understand this. I want to install LVM on top of the single RAID volume, then I can create several LVMs like the HowTos, Wikis and Blogs all say. I just can't get over this first hurdle and get the OS to boot.
UEFI can address 4TB. If you are using BIOS, that could be a problem. With 512-byte sectors, 2TB is about the maximum representable offset.
BTW all the documentation I've seen about BIOS boot sequences assume 512-byte logical sectors. How is BIOS supposed to handle 1024-byte or larger logical sectors?
