Okay, I've recently done the following:
Verified ZFS replication can replace robocopy while vastly decreasing sync time, eliminating using my desktop as a middle-man so less chance of corruption. Tested and verified on two of my QNAP and just need to grab the 3rd from off site and resync 70tb of data to it.
Identified TrueNAS checksum error I've had for a very long time on my server as being both an onboard controller issue and a PSU issue and finally fixed after years. (Also ripped out GPU and soundcard that I was intending to use for game testing which was a terrible idea on this server).
Switched from a netgate pfsense to a N100 mini-pc loaded with proxmox running opensense w/zenarmor and dietpi w/pihole
Switched from ESXi to proxmox on my home server and migrated my Windows (all game launchers) VM, Windows (Steam - macos games) VM, Fedora (Steam Linux games)VM , TrueNAS w/ passthrough to nvme and SAS controller
Easily migrated my ESX vms to proxmox using the new functionality in proxmox to do so but when I moved main windows vm virtual disk from one ssd to another I was unable to boot and due to my unfamiliarity with how proxmox handles disks I deleted it so I'm currently reinstalling all the game clients. Thankfully it was a simple matter to easily connect via iscsi to my 12TB game volume on my TrueNAS VM.
Oh, unlike ESX which doesn't have raid capability I was able to place my 2 8TB nvme drives into RAIDZ1 so my VMs have redundancy now. The 8TB is way overkill since when I purchased them at the time I was using them for my game drive instead of iSCSI so after I set that up I repurposed them.
Right now I'm manually clicking "install" for each of 200+ Amazon "games", which I've been doing for hours. fun fun fun. It turns out that GOG doesn't have the shittiest game launcher. Congrats Amazon!
Next steps for game testing:
Taking "Main Desktop" listed here DosFreak All System Specs 4-25-2025
Put an Nvidia 3060 in it alongside the 7900 xtx
Install Proxmox.
Intended for Windows 7-11 and Linux testing
Taking "Test Desktop" listed here DosFreak All System Specs 4-25-2025
Intended for 2000 w/Extended Core, XP and Vista testing
See if works with Proxmox, if not then using ESXi which I know works
As for games since my storage and backups are stable then I've been investigating winmerge to compare the difference of the game directory backups I keep compared to the main online game store folders, using this method I can identify the latest changes to keep up with the xdelta diffs to be used for the vogonsorg offline site and by using the above test systems I can identify when a update broke os compatibility.
