如何将此驱动器连接到 2TB 硬盘/mnt/？我以为mount -t ext2 /dev/xvdb /mnt会成功，但我尝试的一切都失败了

答案1
您的命令正在尝试挂载设备，而不是分区。
而不是mount -t ext2 /dev/xvdb /mnt，请尝试使用：
mount -t ext4 /dev/xvdb2 /mnt
如果您想在启动时自动挂载此分区，您还需要将该分区添加到 fstab 文件中。
您需要知道磁盘的 UUID，可以使用 找到它ls -l /dev/disk/by-uuid/，然后查找 2TB 驱动器。您的磁盘似乎是 5a99aec9-7270-44ce-9df7-32ff4d70a75b。
然后您需要编辑/etc/fstab并添加以下行：
UUID=5a99aec9-7270-44ce-9df7-32ff4d70a75b /mnt ext4 defaults 1 2
