Hi guys,
I am here again, I have been trying Artix and Obarun, but I think that I feel more comfortable with Debian based distro.
I won't get in the details now but after installation I was able to create BTRFS raid, create my subvolumes, and run Devuan from them. But when I update GRUB it finds a second installation of Devuan when it is actually one. You can boot from SDA1 or SDB1 and you get same environment, but it is unwanted and probably a manifestation of a wrong step somewhere.
How can I get grub recognize properly the only Devuan the lies on the RAID striped mode over two disks?
May it depend by an that version of GRUB itself?
Anyway I found another method that create BTRFS RAID and SUBs during the installation time:

Thanks!

Is this to be a challenge thread then?
Can we at least see the contents of /boot/grub/grub.cfg?

It is not a challenge... But I'd like to have every steps working fine before to post something...

I re-did the installation and this time the issue doesn't happen, perhaps because I did all my steps clearly and in the right sequence, and now I have Devuan on a Btrfs RAID using subvolumes as partitions:

I am almost ready to install Devuan on a real hardware!!!

By the way I think I solved the issue leaving the second disk in a partionless state, other thing is creating /boot outside of the btrfs filesystem; I did the same on my real hardware (WOW!!! ) and it worked.
Soon my recommendations or at least what I did... :-P
