Looking at your original mail again - you are running a raid with metadata 1.2, which means your BIOS will not know how to read the disks as a raid device. You should be able to install grub into the MBR of /dev/sda or /dev/sdb. I believe that is possible with 1.2 metadata. 1.1 was totally broken for this if I remember correctly. That said, if your system is EFI based, I suspect you will need to have the bios_grub partition on the physical drives so the BIOS can read it. It's not going to do much good having it on the raid partition if the BIOS isn't able to read those. BIOS and partition tables isn't exactly my area of expertise, so I could be wrong on some of this.
