I don't understand the need for multiple PCs. Why not run everything from one or two?
well you have all 9 running then same thing, but if there's ever a disagreement, you have them vote...
that's why you always need an odd number of them
I started with three to allow for high availability clustering (under Proxmox), but really that's probably excessive for my situation. So now my production stuff is all on one, and backups go to the NAS. If PVE-Prod1 failed, I just turn the second one on and pull the VM's in from the NAS backups - takes a few minutes, and I actually run everything off it for a week every couple of months to ensure my recovery systems is all working.
The third one I use for software development and other testing of new services. I could have easily managed with two.
I'm also very curious about this!
I have 2 small Dell micros and truenas+qdevice. I have two full replacements of those Dell micros just sitting powered off.
One proxmox Dell is for production. Reverse proxy+outward facing services. The other Dell is for dev/internal shit that i can break and rollback and not care. One is set to run until the UPS is almost dead, other one shuts down almost immediately.
It's just nice to have the options and the power draw is negligent.
