I’ve been running Proxmox in my homelab since version 7.4, and the journey to Proxmox 8.2.2 was to say the least… educational. Let me share some hard-won lessons that might save you some headaches. These even apply to the Proxmox 9 upgrades as well which I have not scheduled in my cluster yet. I’m pretty sure I’ll have updates when I get to that upgrade to share.

I’ve been doing more experimental stuff on my Windows 11 laptops lately - testing sketchy PowerShell scripts, trying out random software, and generally doing things that could completely wreck my system. While I have disk images for recovery, that’s a nuclear option that would cost me a day or two of rebuilding.

Turns out Windows has had a built-in solution for this exact problem: Windows Sandbox. It’s basically a lightweight, disposable VM that resets itself every time you close it. Perfect for testing things without the paranoia.

I want a place to test and try out new features and capabilities in Proxmox 8.2.2 SDN (Software Defined Networking). I would also like to be able to test some Ceph Cluster configuration changes that are risky as well. I do not want to do it on my semi-production Proxmox 8.2.2 Ceph enabled Cluster that I have mentioned in earlier posts. With 55TiB of raw storage and 29TiB of it loaded up with content, that would be painful to rebuild or reload if I made a mistake during my testing of SDN or Ceph capabilities.

I am in the process of building a Proxmox 8 Cluster with Ceph in an HA (high availability) configuration using very low-end hardware and questionable options for the various hardware buses. I’m going for HA, cheapfrugal and reuse of hardware that I’ve gathered up over the years.

Over the COVID lockdown, I was running a Plex Media Server (PMS) on an older Dell Optiplex 390 SFF Desktop that I cobbled into it several Seagate USB3 portable drives that I just slapped on it as I needed more space. It hosted my extensive VHS, DVD and BluRay library as I ripped them into digital formats. To improve the experience I threw a Nvidia Quadro P400 into the mix and a PCIe USB3 card for faster access to the drives. Eventually, I had some drive issues and wanted to get some additional reliability into the mix so tried out Microsoft Windows Storage Spaces (MWSS). Windows and the associated fun I had with MWSS left me incredibly frustrated and I was trying to make an enterprise product work in a low-end workstation with a bunch of USB drives. The thing that made me fully abandon MWSS was the recovery options when you had a bad drive. MWSS probably works well with solid enterprise equipment but was misery on the stuff I cobbled together. So exit Windows OS.

For about ten (10) years, I had run an VMWare ESXi server that let me play with new technology and host some content and services. I let it go awhile back while I was in graduate school and working full-time but have missed this as an option ever since. So adding a homelab server or cluster will let me get some of that back.
