This appears to be a recurring bug, that's yet to be identified. This happens sometimes if you do not have all RAID UUIDs enumerated on the kernel boot command line.

Add any missing raid UUIDs to /etc/default/grub, there should be a "rd.md.uuid=UUID" for each one of your RAID (not partition) UUIDs. Rerun grub2-mkconfig to update your grub.cfg.

I'm using grub not grub2 I'm guessing the procedure is similar, currently I have several entries for the RAID UUIDs but not all:
(it was one long line, I broke it up for readability)

kernel /vmlinuz-3.2.7-1.fc16.x86_64 ro
root=UUID=70ef146a-ba51-498a-9923-8500736d4f1f
rd_MD_UUID=f7d27973:c1e3562c:c97c2b84:778f9f47
rd_MD_UUID=e36e8193:d486ae1b:d9d2d364:ba744b1a
rd_NO_LUKS rd_NO_LVM rd_NO_DM LANG=en_US.UTF-8
SYSFONT=latarcyrheb-sun16 KEYTABLE=us

This makes sense as only 3 of the 5 partitions were "healthy"  I'll continue with the same format for the other two and re-run "grub-install"

Thanks, for the pointer

Jeff
