当我尝试安装其中一个硬盘驱动器时，无法找到带有硬盘驱动器的文件夹。无法安装我的硬盘驱动器
这是命令df输出：

这是当我运行命令fdisk -l：

当我尝试用命令mount -o barrier=0 /dev/sda1它挂载/dev/sda1硬盘给我这个信息：
mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab
我该如何解决这个问题，所以我可以备份所有的东西？
这是当我尝试装入/dev/sdb3：
mount: unknown filesystem type 'linux_raid_member'
然后我试图使用命令mdadm --assemble --run /mnt /dev/sdb3但当时它只是给我：
mdadm: /dev/sdb3 is busy - skipping
这是用猫我的输出/ proc/mdstat
md2 : active raid1 sda2[0] sdb2[1]

md3 : active raid1 sda3[0] sdb3[1]

我可以挂载md3，但没有文件s出现在文件夹中/mnt
对于未在'/ etc/fstab'你需要同时提供设备*和在定位装置用于安装设备“。这正是第一个错误告诉你的。你的'mount'命令没有指定一个位置。 – larsks
