我有以下设置：
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)
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 Ubuntu 并未将它们检测为一个驱动器。
我知道它有效，因为 Windows 可以很好地检测到我的新 4TB RAID 1，这是我的主板附带的 raid 磁盘实用程序 (fakeraid) 之一的屏幕截图。

如何让 Ubuntu 识别我新创建的 4TB RAID 1？
答案1
双启动上的 Fakeraid 有点像一场噩梦。 与 dmraid 相比，mdraid 可能更适合你在 Ubuntu 方面，但仍需要一些工作。 以下是一组不错的建议的链接来自能够为 Ubuntu 12.10 和 Win7 x64 解决此问题的人。
