您好，我正在尝试安装我的硬件 RAID 1 分区，但每次尝试这样做时都会出现错误。
注意：我无法修改其分区，因为它包含大量重要数据。此外，在我今天转到 Ubuntu Gnome 15.10 之前，它在之前的安装中在 OpenSuse 42.1 和 Fedora 23 上运行良好。
我相信我缺少一个包或其他东西，因为 Ubuntu Gnome 无法识别 RAID 1 分区。

我得到了更多信息。我安装了 gparted，结果如下。

dumpe2fs: Invalid argument while reading journal super block</i>
Unable to read the contents of this file system!
Because of this some operations may be unavailable.
The cause might be a missing software package.
The following list of software packages is required for ext4 file system support: e2fsprogs v1.41+.
看起来 e2fsprogs 存在一个问题。
此外，我还做了：-

Description: ext2/ext3/ext4 file system utilities
The ext2, ext3 and ext4 file systems are successors of the original ext
("extended") file system. They are the main file system types used for
hard disks on Debian and other Linux systems.
.
This package contains programs for creating, checking, and maintaining
ext2/3/4-based file systems. It also includes the "badblocks" program,
which can be used to scan for bad blocks on a disk or other storage device.

Ubuntu 15.10 使用的是版本 1.42.12-1ubuntu2，而 e2fsprogs 主页使用的是版本 1.42.13。
我假设我使用的版本可能有一个错误。
有没有什么办法可以解决这个问题？请给我建议。

在安装 raid 分区之前，您需要确保您已为该分区创建了文件系统。
mke2fs -t ext4 -L <label> <block_device>
mount <block_device> /media/ahmad
