[Bug 1327133] Re: RAID1 installation of grub: grub-install /dev/md127p2 failed

[Salih EMIN]

Thanks @psusi for your comment. The problem is that when selecting the default settings as I described there is no option of sellecting /dev/sda. 
What should have happend when a user selects default (Erase everithing and install Ubuntu) grub-install should detect RAID aray and install it aproprietlly. Instead what happens is, as I described grub fails with grub-install /dev/md127p2 failed and propmts you to select other partition where ther is NO /dev/sda as option only :  /dev/md127,  /dev/md127p1,  /dev/md127p2,  /dev/md127p3.
