当我尝试安装我的一个硬盘时，它无法找到该硬盘的文件夹。
这是该命令的输出df：

当我运行命令时出现这种情况fdisk -l：

当我尝试/dev/sda1使用该命令安装硬盘时mount -o barrier=0 /dev/sda1，它会显示以下消息：
mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab
我该如何解决这个问题，以便可以备份我所有的东西？
当我尝试挂载 /dev/sdb3 时出现以下情况：
mount: unknown filesystem type 'linux_raid_member'
然后我尝试使用该命令mdadm --assemble --run /mnt /dev/sdb3，但它只给了我这个：
mdadm: /dev/sdb3 is busy - skipping
我怎样才能解决这个问题？
答案1
由于 sda1 不在 fstab 中，因此必须指定挂载点，例如
mount -o barrier=0 /dev/sda1 /mnt
然后您将能够在/mnt 中找到您的文件。
