I'm the maintainer for the G4L disk imaging project since version 
0.15 to the current 0.37, and working on 0.38. 

Backing up the regular partitions that contain an LVM has been 
always been available, and backing up the whole disk image. 
Recent versions have added the ability to backup the LVM dm 
partitions as well. Backing up and restore works fine as long as 
the LVM setup is already there, but it a disk completely fails one 
would need to recreate the LVM before being able to restore it.

Similar to how one backs up the MBR and partition table for disks, 
I'd like to have a method that would allow for the recreation of the 
LVM, so that restores could be done. Additionally, with the 
fsarchiver doing backups of files in use, it is generally faster than 
doing a raw dd type backup. 

Is there a script or how to that explains the process of creating a 
script to recreate the LVM from scratch or from an already existing 
partition table?
