On my old system I use 1TB disks, with /boot as raid1, and grub boot-loader installed on all disks. On that one I can boot the system from any of disks. Which is quite handy.
The problem here seem to be that due to the disks being large (larger than 1TB) they are setup as GPT (GUID Partition Table), and they then also need a BIOS boot partition to work on non UEFI based systems (if I have understood it correctly).
So, to be able to boot from any of the disks, I need a BIOS boot partition on all disks, but anaconda seem to only install it on one of the disks (i.e. I want the exactly identical partition tables on all disks).

gdisk will seamlessly convert an existing DOS partition table made by say fdisk, parted, gparted, ... to GPT format on the fly without disturbing the any actual parttions ( you may want to back up first though ... ) .
Additionally, I have not had any problems getting 3-4 year old standard dumb BIOS to boot from a 3TB drive . Never tried with UEFI though.
