解决方案：我能够安装该分区并将文件复制到另一个驱动器！
sudo fuseext2 -o ro -o allow_other /dev/mapper/vg1-lg1 /mnt
是关键。我仍然无法通过 nautilus 访问文件，但我可以通过终端复制重要内容。
我正在尝试使用 14.04 live USB 从 seagate central NAS 安装一个驱动器，以确保在将此桌面变成我的新 NAS 之前硬件可以正常工作。我找到了带有 gparted 的分区 - 列为 /dev/sdb8，但我无法将其安装。它上面有我不想丢失的东西（图片/电影/等等），所以我不想直接擦除它。
到目前为止，我已尝试使用 apt-get 更新/安装 lvm2 - 它告诉我这是最新版本。我在 fstab 中输入了 UUID，并为其指定了一个挂载点。现在，当我运行 sudo mount /dev/sdb8 时，我收到消息“mount：未知文件系统类型 lvm2”（当我尝试将 fstab 中的文件系统更改为 lvm2_member 时，我得到了同样的结果。
我尝试改变一些东西，一个反复出现的主题是错误消息“缺少代码页或辅助程序，或其他错误”，它提到/dev/mapper/vg1-lv1 上的坏超级块。
如果可以的话，我会马上用一些终端内容来编辑它。（已编辑）
希望有人能帮助我解决这个问题，提前谢谢了。

答案1
你没有挂载分区包含LVM，挂载分区包含在LVM。请尝试挂载，/dev/mapper/vg1-lv1而不是/dev/sdb8。
此外，由于该驱动器来自非 x86 NAS，您可能需要通过fuseext2非标准块大小来安装它（阅读这个问题）。
