[Bug 1258111] Re: Ubuntu installer unable to install GRUB to software raid

[Phillip Susi]

It has been possible in the past since they were managed by dmraid and
grub had hooks to recognize that and understand that the bios recgonizes
the array as a single drive.  I started some discussion upstream maybe a
year ago about how to proceed with the mdadm transition and being able
to detect whether or not the bios handles the raid but it was never
resolved.  If you are working on the mdadm migration that is something
you will need to work out.
