在 Ubuntu 16.04 LTS 中安装硬件 RAID

我为我的服务器添加了硬件 RAID。它配置了 LSI-MR9361-8i，为 87TiB RAID 10。

sudo fdisk -l返回：

当我去挂载 /dev/sda 时sudo mount /dev/sda /mnt/UB_RAID出现以下错误。

mount: wrong fs type, bad option, bad superblock on /dev/sda,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

显然，我想要 87TiB，但这里发生了什么？我应该能够很容易地安装它。

谢谢。

首先必须在块设备上创建一个文件系统，然后才能挂载它。

例如：

mkfs.xfs /dev/sda
