"For like 8 months" is quite a long time when you consider all the damage Trump has done in the 4 months since his inauguration while Senate Republicans only hold 53 seats.
Obama's early policy of negotiating with himself to try and appear bipartisan.
They haven't stopped following that policy which is exactly why they face so much criticism and keep losing elections. Their talk is cheap and they're more than willing to help Republicans destroy the country.
You might look at TechHuts previous tutorial on setting this all up from around a year ago where he instead used Cockpit to manage his ZFS pool shares rather than TrueNAS. I followed that one a few months ago with a minor amount of Linux experience and got everything set up on Proxmox quite easily. I do recall some people complaining about having issues with permissions or some such which is why he created this new tutorial, but I didn't run into those issues for whatever reason.
This new Proxmox build has been rock solid after running everything on flaky laptops, mini PCs, and a Windows-based server build for the past 12+ years and I've also used it to now run things like Jellyseer, Immich, Frigate, and more which is awesome, but I did spend a good chunk of money for a lot of new hardware, redundant SSDs, RAM, etc so you may be better off starting with something more basic to tinker and learn with.
