У меня есть 256 ГБ SSD (Ubuntu/Win8) и два диска по 1 ТБ в RAID 1.
Проблема в том, что я только недавно добавил еще два диска объемом 4 ТБ в RAID 1, но они не обнаруживаются в Ubuntu как один диск, а как отдельный.
Я знаю, что это работает, потому что Windows обнаружил мой новый 4TB RAID 1 очень хорошо, вот скриншот с помощью одной из утилит raid disk, поставляемых с моей материнской платой (fakeraid).
Также вот информация о fdisk для моей установки:

This doesn't look like a partition table
Probably you selected the wrong device.

Как я могу заставить Ubuntu распознавать мой только что созданный RAID-массив 4 ТБ 1?
