#115 Help with LVM Partitions Restore

[Inukaze]

Hi there, today, on my job, my boss, tell me need an urgent backup of hard drive. i clone the hard drive. and have LVM. i create the image from wizard "device-image" all normal.

But when i restore to the hard drive, the LVM partitions and subvolumes are not restored. have a volume group called "Sistemas" inside "Ubuntu" (18.04) and "Debian" (9.4) (74 GB in total). but i don't know how is the right way to restore without problems. because of that, the grub, can't start, obviosly the partition try to find dont exist.

In the hard drive when i restore the LVM2 (in this case the /dev/sdb5), the partition have flag LVM, but just say type "Unkown" (for example in gparted)

which is the correct why to restore the partitions inside the mapper?

Looks like it should be OK for Clonezilla live to backup and restore for you. Which version of Clonezilla live did you use?
Have you tried the latest Clonezilla live 2.5.6-22 ro 20180812-bionic?
