Debug installing Fedora with RAID partitions

I'm trying to install Fedora onto a pair of 250GB hard drives with either RAID0 or RAID1.

Debug logging

The issue seems to be the following from journal.txt:

Dec 05 21:27:51 server anaconda[1647]: program: Installing for i386-pc platform.
Dec 05 21:27:51 server anaconda[1647]: program: grub2-install: warning: ../grub-core/partmap/gpt.c:190:this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
Dec 05 21:27:51 server anaconda[1647]: program: grub2-install: error: embedding is not possible, but this is required for RAID and LVM install.
