如何挂载 LVM 分区？

Question

我试图更新 Java，我使用了一颗星来确保它被完全删除，但没有意识到它会搞砸一切

我用了

apt-get remove java*

这是在 Ubuntu 16.0 或其他服务器上。我现在在服务器上有 sysrcd 或 System Rescue CD，我正在尝试取回我的旧文件以将它们放在新服务器上并将 sysrcd 服务器重新加载回 Ubuntu。但是我似乎无法弄清楚如何使用安装系统。

我试过跑步

fdisk -l

我得到

我不确定要安装哪个驱动器或如何安装它。有人可以帮忙吗？

挂载LVM分区与非 LVM 分区时需要更多的步骤。

sudo apt-get install lvm2   #This step may or may not be required.
sudo pvscan                 #Use this to verify your LVM partition(s) is/are detected.
sudo vgscan                 #Scans for LVM Volume Group(s)
sudo vgchange -ay           #Activates LVM Volume Group(s)
sudo lvscan                 #Scans for available Logical Volumes
sudo mount /dev/YourVolGroup00/YourLogVol00 /YourMountPoint
