输入:硬盘的 RAW/DD 映像。fdisk -l
显示分区
fdisk -l image.dd

尝试使用start-sector*sector size
(如描述在这里;通常用于安装分区)会带来错误
(„mount: /mnt/vmdisk: unknown filesystem type 'LVM2_member'.“
可以找到最充分的解决方案这里使用诸如、、lvm2
等工具;但这些工具vgscan
vgchange
lvs
没有扫描原始文件的选项对于这些卷。
那么如何才能访问Linux LVM
使用的内容mount
或者类似的东西呢?

安装 kpartx
sudo apt-get install kpartx
dev/mapper
整合使用中的卷
sudo kpartx -a -v image.dd
检查dev/mapper
你的分区
administrator@cdc-ansible:~$ ls -l /dev/mapper/

lrwxrwxrwx 1 root root 7 Nov 19 12:50 loop2p5 -> ../dm-2
然后sudo lvscan
找到 lv 的名称:
sudo lvscan
ACTIVE '/dev/123--yourname--ewu--vg/root' [12.71 GiB] inherit
ACTIVE '/dev/123--yourname--ewu--vg/swap_1' [<2.00 GiB] inherit
尝试再次挂载:
sudo mount /dev/123--yourname--ewu--vg/root /mnt/rootfs
已挂载的文件系统(tada!):
ll /mnt/rootfs/
