Thank you for the notes. I followed them, but I'm still not having any luck installing. I go to shell and create the arrays and create the config files, but when I switch back to anaconda, it doesn't detect /dev/md10, only /dev/md11 and /dev/md12. I can't create another raid device in anaconda. What am I doing wrong? I tried setting up LVM when i first installed this, but it failed to boot.

I don't believe you can boot from any device that includes RAID-0 in its components. This is because the kernel is what knows how to drive a RAID-0 device, whereas the Grub loader knows how to do is read linearly.

At a bare minimum, your /boot must be non-RAID0 and non-LVM.
