"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).

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
kvdo - A kernel module which provide a pool of deduplicated and/or compressed block storage.
precomp-cpp - Precomp, C++ version - further compress already compressed files
preflate - deflate stream reconstruction library
