ubuntu linux 下面mount fedora 逻辑卷 lvm的方法

今天fedora挂了，为了备份数据用ubuntu的livecd来进行数据备份，从网上看到了一篇帖子，

解决了问题
内容如下：
Boot Ubuntu.
Install lvm2:
$ sudo apt-get install lvm2
Load the necessary module(s):
$ sudo modprobe dm-mod
Scan your system for LVM volumes and identify in the output the volume
group name that has your Fedora volume (mine proved to be VolGroup00):
$ sudo vgscan
Activate the volume:
$ sudo vgchange -ay VolGroup00
Find the logical volume that has your Fedora root filesystem (mine
proved to be LogVol00):
$ sudo lvs
Create a mount point for that volume:
$ sudo mkdir /mnt/fcroot
Mount it:
$ sudo mount /dev/VolGroup00/LogVol00 /mnt/fcroot -o ro,user
Copied my files.
