我无法再更新我的 ubuntu-server。
df说/仍然只有4.7M，但lsblk说74GB...另外对我来说，似乎 74GB 根本/dev/sda3没有安装。到目前为止，这些设置都是默认的，`/etc/fstab' 中没有更改。在我重新启动之前，它已安装。我现在必须手动安装它吗？我应该把它挂载到哪里？
谢谢你，

和
If you're asking why the LVM2_member size shows 148G but / shows only 74G, that's presumably because you only created a 74G filesystem on the LV
