Fakeraid не отображается в / dev / mapper

У меня следующая установка:

1 256GB SSD / Win8-Ubuntu 13.04 UEFI Dualboot
2x1TB in RAID 1 (Detected and working)
2x4TB in RAID 1 (Not Detected not showing up in /dev/mapper)

Проблема в том, что я недавно добавил еще два диска емкостью 4 ТБ в RAID 1, но они не обнаруживаются в Ubuntu как один диск.

Я знаю, что это работает, потому что Windows без проблем обнаружила мой новый RAID 1 емкостью 4 ТБ. Вот снимок экрана с помощью одной из утилит raid disk, поставляемых с моей материнской платой (fakeraid).

Как я могу заставить Ubuntu распознавать мой недавно созданный RAID 1 емкостью 4 ТБ?

Fakeraid на двойной загрузке - это своего рода кошмар. Скорее всего, вам будет лучше с mdraid, чем с dmraid на стороне Ubuntu, но это все равно потребует некоторой работы. Вот [n в архиве] ссылка на хороший набор советов от кого-то, кто смог разобраться в этом для Ubuntu 12.10 и Win7 x64.
