我的家庭实验室里有一台安装了 H710 RAID 控制器的 Dell R720 服务器。我使用板载控制器和 8 个 4TB HDD 构建了一个 Raid5 阵列。我能够在 fdisk 中创建一个分区而没有任何问题，但是当我去安装它时，我收到以下错误消息：
~$ sudo mount /dev/sda1 /mnt/raid_array/
mount: /mnt/raid_array: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error.
我不确定这个错误意味着什么或如何解决它。我几乎可以肯定这不是一个坏的文件系统，但我会附上我能想到的所有相关内容的屏幕截图。
这是 lsblk：
$ lsblk

大概/dev/sda是您的硬件 RAID 的演示。我想说您似乎尚未在虚拟磁盘上创建文件系统。
mkfs.ext4 -L bigdata /dev/sda1
mount /dev/sda1/mnt # mount it
但在此之前，请考虑一下您是希望拥有 25TB 的文件系统，还是将其分配为逻辑空间 (LVM) 更有用，以便您可以根据需要从中划分文件系统
pvcreate /dev/sda1 # disk partition to use
vgcreate myvg /dev/sda1 # "myvg" is name of the logical volume group
lvcreate /dev/myvg --name mylv --size 100G # "mylv" is logical disk volume
mkfs.ext4 -L myext4 /dev/myvg/mylv # create filesystem
mount /dev/myvg/mylv /mnt # mount it
LVM 成功的关键不是将整个空间分配给单个文件系统，而是根据需要（在合理范围内）扩大它。
