kvdo VS vdo

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

git clone https://github.com/dm-vdo/kvdo.git $WORK_DIRECTORY && \

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.

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.

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).

Update : the project is progressing and I managed to install VDO on Debian 11(.3) : https://github.com/dm-vdo/vdo/issues/47
