I have three drives: two 1TB hard disks, one 120GB SSD. I want to install Ubuntu (preferably, but justified alternatives are fine) and Windows 7 on the SSD, and have them both read from the other two drives as a mirrored RAID pair (RAID-1). These drives do not need to be bootable, just accessible from both OSs (and properly mirrored on both.)
I've had a good look through my bios, and there's no support there, and I'd rather not go out and get a hardware card. Another SU post suggested just setting up the 1TB disks as mirrored volumes in Windows 7, and seemed to suggest that would just work, but Ubuntu ignores that completely, and seems to show the drives as independent disks, which happen to have the same thing on them, and that is not a good solution.
TL;DR: Does anybody know how to set up software RAID-1 data disks that work from both Windows 7 and Ubuntu?
