在 Ubuntu 13.04 中无法识别两个 RAID 1 之一

Question

我有一个 256GB 的 SSD (Ubuntu/Win8) 和两个 1TB 的 RAID 1 驱动器。

问题是我最近刚刚在 RAID 1 中添加了另外两个 4TB 的驱动器，但它们在 Ubuntu 中没有被检测为一个驱动器，而是分开的。

我知道它有效，因为 Windows 检测到我的新 4TB RAID 1 就好了，这是通过我的主板 (fakeraid) 附带的其中一个 RAID 磁盘实用程序的屏幕截图。

另外这里是我的设置的 fdisk 信息：

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

如何让 Ubuntu 识别我新制作的 4TB RAID 1？

Answer 1

经过大量研究，fakeraid 似乎不支持大于 1TB~ 的驱动器。我被迫购买了一个突袭控制器，它的作用就像一个魅力。感谢大家的投入和时间。
