Make sure that you are booting and installing the system using the UEFI bios, not the legacy bios. You'll need to check your bios setup for the setting to do this if the system supports it.
The legacy bios will force the MDOS labeling scheme that will limit the boot drive to a maximum of 2TB. The UEFI bios allows the system to boot from a large GPT labelled disk (with the required UEFI partition).

Hello, I'm a newbie so here's my question.
I'm trying to install CentOS 6.5 on a HP Proliant 350e server. This server has 4x 1TB hard drives. I'd like to enable the hardware RAID 5 and stripe all 4 disk into one 3TB logical volume. Then install CentOS on the 3TB volume. However after I install I can't get the server to boot.
I know about the MDOS vs GPT labeling issue. I've successfully installed on one (singular) 3TB disk on other servers. I have modified the partition tables, relabeling them to GPT, prior to completing the installs.
However I've read that the Anaconda installer still tries to format as MDOS and after installing a Basic server I cannot get it to boot.
So, what am I missing? Can I load CentOS on a hardware RAID 5 volume that is 3TB (usable) or am I stuck with what most Google searches say and load the OS on one disk and then after use software RAID to RAID 5 the remaining 3 disk into a /data directory?
All help is appreciated.
