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中增加了两个4TB的驱动器，但是在Ubuntu中没有将它们作为一个驱动器检测到。

我知道这是有效的，因为Windows检测到我的新的4TB RAID 1就好，这是通过我的主板（fakeraid）随附的RAID磁盘工具之一的截图。

• 将PERC h310升级到Dell R620上的PERC H710 mini RAID控制器
• 如何执行连接到LSI RAID控制器的磁盘testing
• 戴尔突袭configuration问题omsa
• 在RAID-0升级到三星三星SSD EVO – 寻找什么types的RAID控制器？
• RAID控制器使用相同的磁盘显示2个arrays

我的4TB驱动器/dev/sdd和/dev/sde应该被识别为ddf_raid_member但是无处可寻。

blkid -p / dev / sdd

这个命令没有输出
