After a lot of Googling and trying, it seems like it is time for me to choose OMV.
For a few years now I have been running Ubuntu Server 16 and 18.
But for home use I want a admin gui and I really like what I see with OMV.
The only cloud on the sky says "Ryzen", latest 4.x OMV comes with kernel 4.14, what I have managed to find out.
But now I found that I can install OMV on Debian, which menas I can install Debian first and fix all the stuff I need there, among other things update the kernel for my Ryzen CPU.
I hope this forum is way better than FreeNAS... first comment made me decide to leave it.
My setup is in the signature.
