reinstall/upgrade Debian over existing LVM on LUKS partition
 

Is there any documentation for reinstall/upgrade Debian over existing LVM on LUKS partition instead of recreate the whole disk (only format / volume, and keep /home volume).

I tried more than 2 ways from AskUbuntu forum, I did everything as explained, and keep getting:

ALERT! /dev/mapper/debian-root does not exist. Dropping to a shell!

BusyBox v1.22.1 ......blah.........blah.......blah.......
(initramfs) _

So; just curious about an alternative way If you don't have time to backup you /home (user data), and packages cofig files, and do it again from Scratch.

BTW, some rarely situations like this need more discussions.

Are you just trying to upgrade from Debian 8 to 9?
