Comment 6 for bug 743136

kvv, can you please give me a recipe for reproducing this problem, and ideally also full installation logs of your latest test? I tried the simple case of two 10GiB disks in kvm with a single RAID-0 array spanning them both, and an ext4 filesystem on that; GRUB installed and booted with no problems.

It will be a great deal easier for me to fix your problem if I can reproduce it.
