"lvextend" freezes my Debian server
It is true that I have not had time to concentrate fully on this issue in the last days, and it is difficult for me to understand some of the subtleties of the subject (english is not my main language). I would like to thank you for your help and patience! I really appreciate it. FYI, I will continue to work on this issue and will update this topic. I've also asked the VDO development team to take a look at it and to tell me if they have any ideas, you can see that discussion here.

New LVM VDO logical volume inactive at startup, even with "--activate y" parameter
No problem, maybe someone else will read it and be able to clarify all of this. I also asked the question on VDO Github repository.

Which directories should I move to a compressed/deduplicated volume ? Which should I not ?
Still working on this project, I can now compile and run LVM VDO under Debian, which is a great thing (I shared the script here).

How do I keep custom kernel modules working after kernel upgrade ? (Debian 11)
This is intended for building an rpm, but as far as I can see, you can steal the dkms commands and config file out of it: https://github.com/dm-vdo/kvdo/blob/master/kvdo.spec

- kvdo. Can I use it on root partition?
What are some alternatives?
When comparing vdo and kvdo you can also consider the following projects:
ansitest - ansible test stuff and root/bin bash scripts for Linux / OSX admins
anbox-modules - Anbox kernel modules
kvdo - A pair of kernel modules which provide pools of deduplicated and/or compressed block storage.
libpostal - A C library for parsing/normalizing street addresses around the world. Powered by statistical NLP and open geo data.
precomp-cpp - Precomp, C++ version - further compress already compressed files
