Some relevant info
8 x 1 TB drives in a raid 5 (hardware raid)
This system currenlty works on Centos 6.4 and has the OS installed
However when trying to setup a new install using Centos 7, apparenlty there are a few issues which I am unable to get around so far
1) It tries to install using "biosboot" mode, however when trying to create a 1M biosboot partition as suggested, it can not create the device. My understanding is Gen8 HP does not support UEFI mode and I can not find anything in the bios to disable legacy (BIOS) mode to give that a shot
2) It also complains about not supporting larger than a 2TB volume for OS (boot drive) install
I believe both of those are related to how the newer linux kernels interact with the older hardware (raid controller, etc) and legacy (bios) mode.
Has anyone run into this situation and found a workaround?
Thx
