如何挂载LVM分区？

我正在尝试更新Java，并使用星号来确保将其完全删除，但没有意识到它将使所有内容弄乱

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，我试图将旧文件放回新文件中，然后将sysrcd服务器重新加载到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，还需要执行几个步骤。

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
