我将在我的 ubuntu 14.04 服务器上进行 RAID5 设置。我有 2 个 4 TB WD NAS 驱动器，并购买了另一个。但是，当我尝试使用 pvs 在系统中查找这些驱动器时，我只找到 3 个驱动器（我的系统驱动器和两个附加驱动器）。

所以 sdc 驱动器没有显示在 pvs 中。在进行 RAID 之前这是需要担心的事情，还是我应该继续前进？
提前致谢.. ：）
答案1
pvs不列出物理驱动器，它列出物理卷。您需要先创建一个物理卷，然后它才会出现在pvs' 输出中：
pvcreate /dev/sdc
或者
pvcreate /dev/sdc1
（如果您已经对驱动器进行了分区，则为后者）。
