Bug Description
I can produce the issue on Ubuntu 18.10 "Cosmic Cuttlefish" - Alpha amd64 (20180916) and Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180916).
This issue is after LP: #1779685.
First of all, there is no mdadm in the Ubuntu desktop images so I need to install it manually.
After I installed mdadm, I can install the system on Intel VROC.
However there is an error about grub-install.

Please run 'sudo grub-install -v" from the live image; we should have a look at the full debug output to see why md126,1 isn't found.
That said, typically RAIDs are installed by installing grub to each member separately; which is handled by grub-installer. You don't run through these steps when doing an install on desktop, which isn't set up to support RAID.
