On Regular Maintenance

As I've mentioned before, I run a Proxmox VM server at home. It's a fun insanely-overpowered bit of hardware I've cobbled together over the years from what I had on hand or could get for as close to nothing as I could.

One foreseeable problem with the setup is I initially set it up with cheap consumer SSDs for boot drives. Proxmox is very heavy-handed with SSDs and I've been watching the wearout on one of the drives steadily tick higher.

Well the day finally came. I woke up to an email from the server informing me of a SMART error on one disk: wearout had hit 101%. Definitely time for replacement before things go south.

Luckily I had been procrastinating was prepared for this event and had new SSDs on-hand to swap in.

So a fun evening of watching paint dry ZFS resilvering followed. Sure beats data loss.

SysAdmin Sunday

One of my ProxMox hypervisor machines has a failing disk. Of course, it's the disk that stores the root filesystem of my homelab DNS server.

remediated by pulling a backup of running Pi-hole and restoring to the other hypervisor, running from an NVME drive now.

The best thing about running a Pi-hole, besides the whole house ad blocking thing, is the skinnable interface.

Proxmox has a lot of momentum behind it as of recently. We had the recent news of the new Proxmox import wizard to import VMware ESXi guests in Proxmox virtual environment. Also, Proxmox 8.1 wasn’t released that long ago. However, Proxmox has now released Proxmox 8.2 new features and you can now download the ISO for installation. Let’s take a look at the new features contained in this…

If It's a Hack and It Works, Is It Really a Hack?

I have a couple servers at home — one running Proxmox VE and one running Proxmox Backup. I use the VM server when I need to spin up a development environment, for running the odd game server, serving files locally, running Home Assistant, etc. I also like to donate spare cycles to Folding@Home. The backup server of course is in case I do something stupid on the VM server.

There's just one problem with that. My second-hand 8-year-old dual-Xeon server runs hot.

It was too much to keep running in my home office. Between the two servers, my desktop, and my work laptop, I was regularly seeing ambient temperatures around 26°C. It was just too warm for comfort.

Last summer I moved my network gear and the two servers into the front coat closet. This was great for me working in my home office, but not so great for my servers. Despite adding a passthrough vent to the closet door and a vent fan to the ceiling, the closet was still consistently in the 26°-30°C range.

The ideal solution would probably be to use an enclosed server rack and run an exhaust vent up from the top. Unfortunately, rack-mount server cases are expensive, enclosed racks are very expensive, and my closet is too small for that anyway.

So I hacked together a solution.

I built a frame out of some cheap 1x2 lumber and wrapped a piece of thin sheet steel around the sides to make a crude plenum. On top, I added a 10x6 register box with a semirigid vent hose coming out of it. This gives me a guide for drawing air out of the servers and guiding it up to the vent fan in the ceiling.

To help things along, I added a 120mm fan inside the register box. But not some whisper-quiet Noctua. This is (if the Amazon listing is to be believed) a 5000 RPM, 210 CFM monster of a fan. It's loud, but moves a lot of air.

Too loud in fact. Its droning could not be silenced by any mere closet door. I had to add a PWM fan speed controller to calm it down. It's a cheap unit from Amazon, but it came with a temperature probe and it has a configurable operating range.

The result? Where previously the entire closet was consistently above 26°C, now it's staying around 23°. There is a difference of 5°C between ambient in the closet and the air inside the exhaust duct, so it is doing its job of redirecting the hot air from the servers.

I call that a successful hack.

Setting up a Proxmox home server

I received a Beelink S12 Pro Mini PC as a Christmas gift and set it up as a home server over the holidays. My home setup has a unique challenge: I can’t access both an Ethernet connection and a monitor in the same location. Booting the Proxmox installer from USB I connected a keyboard and monitor to the Beelink, and followed these steps to start the Proxmox installer: Download the PVE ISO…

ok actually i found out that not having my laptop (getting my keyboard replaced) means i forget like half the ports of the things i host. so i made a lil dashboard. its running Homepage [^] and i set it up so it shows all my nodes, virtual machines, and lxc services. screenshot coming later, i have to edit out some stuff due to an nda

IT stuff knocking around in my head and what I've been doing the last 3 years

Got this idea to get my old radio station running again last night (06/10/2024) and now I'm definitely doing it. Tippy Radio will rise once more! I created my own Network Attached Storage System (NAS/File Server) back in 2020 with a Raspberry pi which then also became a plex server to stream all the films and tv shows in my collection in the home and outside. Eventually I figured Proxmox would let me do more with just the one pc and now it's grown into an adblocker with plex and my nas all in one. The old pc I'm using is a Dell Optiplex 3050 with an i5-6500T and 32gb of ram. It's not fast by any means with just 4 threads and no hyperthreading but she does the job for now. I'm upgrading as soon as I get the funds saved up to a Ryzen 9 7900 with 96gb of ram. I didn't choose the 9900X because I want more efficiency as a whole but I will be tweaking the voltage a little since I'm a classic undervolter so I'll try and squeeze a little bit of extra performance without using extra power. My plan after the upgrade is potentially to get my old radio station running again with MacOS in a vm. So far I've managed to get Sequoia running but with the new machine with 12 cores and 24 total threads, it'll damn near fly. My other idea for the server since I've started using Steam Remote Play outside the house is to add my 6700xt from my current gaming rig to the server and pass it through to a Windows 11 vm and then remotely play games around the house. The challenge is making Windows believe it's running on bare metal. Even though I don't play multiplayer games, I'm not trying to have my account banned for the anti-cheat considering a virtual machine to be cheating It's funny how teachers in college and school said I would never be an IT guy but I've consistently been the family and friends IT guy people go to for advice since I was a kid.
