Apparently.

At some point I got a bug up my butt and wanted to use Proxmox in a workstation style configuration. Initially it was so I could practice spinning up VMs and maybe have a bit of HA/redundancy when needed.

This was foolish lol.

Do NOT cluster proxmox nodes unless you understand the implications and need the functionality.

I also run Proxmox on a HP Prodesk minipc. It runs a VM for a secondary Docker setup, as well as VMs for my 3D Printer/Repetier and another for an SDR Streaming setup.

So I clustered them figuring it made sense on some level. Shows my lack of understanding of those systems.

I eventually decided to try and uncluster them. This was a second massive mistake. It broke all sorts of layers of Proxmox. I couldn't SPICE connect to a VM. Was getting corosync errors at boot/shutdown. Determined that it was going to basically require a full reinstall to undo all the fuckery.

Best part is I get to repeat this on the HP as it is in the exact same situation I got my desktop in.

Luckily I've been annoying AF about taking backups. They're stored on my main server and easily accessible from both the Proxmox nodes. It's saved my ass quite a bit the past weeks.

That said I think I must've bungled that first install on my desktop, as it just seemingly had a few weird quirks. I can't remember them off the top of my head but performance just felt off. It doesn't now. I recall having issues getting the DM and DE working properly that first go around (using lightdm and MATE). No such issues this time with lightdm and XFCE (sparse Kali use convinced me to try it).

I must've borked my EFI partition during the reinstall however. GRUB wouldn't find the EFI folder in the Windows partition, because it isn't FAT format. Luckily I was able to use the repair features of the Win11 install ISO to get that all fixed up.

I'm still not sure it's the best setup, guess we'll see long term. Luckily the PC has the untouched Win11 install. Mainly so far I've just setup a Win10 VM with a bunch of work centric stuff (and ability to access work storage and printers via VPN). I also have a Kali VM for more secure internet browsing (it's permanently tunneled via VPN, isolated from the rest of my network).

It's been one hell of a learning experience. Had fun (though in the thicc of it you wouldn't be able to tell that lol). Gaming on Proxmox is probably a bit outlandish but hey it is what it is. Roadcraft wouldn't work on Win11 but it worked in Linux.
