What is your weirdest self-hosting problem you've had to solve? For me: Mouse inside the server.

  I used to have a Ryzen 2700X based system as a server. At the time (no clue if it’s still an issue), there was a bug in the interaction between early Ryzen chips and Linux that caused the OS to lock up intermittently. I used a ATmega32u4 board to connect to the reset switch on the PC and as a USB device with a systemd unit that sends a ping to the board every 30 seconds. If the board doesn’t see a ping for a minute, it reboots the PC. It was janky as hell, but it worked for 2+ years!

    That reminds me of the old story where they positioned a PC opposite from the server and taped a pen to the CD drive so that opening the CD tray presses the reset button of the server. The PC would automatically detect when the server freezes and open the CD tray. Probably just a legend but still a great example for how a silly and simple solution that just works can often times be as good if not better than a sophisticated but over engineered solution

    so you reinvented watchdog?

      yes, it’s a zip-tie-and-duck-tape watchdog that cost me $5

  My WAN connection would just randomly start losing packets and would not recover, not full disconnect just lots of retries. Didn’t impact LAN just WAN. Unplugged the cable or disabling then re-enabling the interface would fix it for a coupe of days to a week then it would come back.

  Time consuming to diagnose as switching cables, ports, etc would require waiting days to see if it fixed it.

  Eventually had the ISP come out and swap the fiber media converter and fiber integrity. But again it came back.

  After several weeks I stumbled on a FreeBDS bug that was exactly my issue…I was running OpnSense and my gateway had I225s. Applied the scripts and it worked.

  I dunno if that counts or if it’s the weirdest cause I rarely have any issue, but one day, I wanted to deploy speedtest tracker via docker on my 1st NAS..

  So I tried, but it didn’t work (I forgot the reason). So I try to check the logs, but it turns out my NAS was insanely slow.

  When I rebooted it, it couldn’t stop beeping and telling me there was a hardware problem, so I tried everything I could do to fix it, but nothing worked, so I ended up reinstalling the whole OS

  Keep in mind this was the cost to see I had a bad result at the speedtest lmao 😭

  Btw, I also lost all my important files, yayyy!

  I thought that heatsink and fan was a spindle of CDs! I thought that was an interesting place to store them I hadn’t seen before…

  Not on a computer but I had a JVC TV that started blanking a few times a minute whenever my dvd player was connected. Whilst trying to fix this I attempted to update the TV firmware. That didn’t fix a thing but I noticed that the blanking went away when the USB drive with the firmware update was plugged in. So I just plugged a cheapo USB drive in and left it there for as long as I owned that TV and dvd player.

  The backup server at my parents house really did not want to run. Something kept breaking to the point that no web interface or SSH worked. Now I’m not new to self hosting, so I ran my fair share of HDMI and USB cables across my space to debug something on my server. But at my parents place it’s just that extra bit annoying, since I only bring my laptop. Finding a screen is doable, but the keyboard got me more than once. The only one they have kicking around has a freaking PS/2 cable… not even my salvaged backup hardware is old enough to support that. Not just once I had to wait for friends to get back from work so I could borrow their keyboard just to press ‘any’ key.

  I decided to handle the issue by getting an IP KVM, which should help me deal with that, right? Wrong! I installed a new drive and that piece of **** goes into some secure boot loop or whatever that is too fast for my KVM to turn on…

  I do not care to admit how many times when I was first getting into home labbing that I could not figure out why I could not reach a pi or the internet. All because I either killed an SD card for pihole or just plain out forgot to put one in!

    I took my SD card out of the rpi to reinstall home assistant. Terribly annoyed because I had no backup of my configuration.

    When reinstalling my SD I found out it was the ethernet cable that wasn’t plugged in.

      I should really make a dd image of my card for the Pi I use for all my switch serial connections.

      I am so afraid of an SD card dying and killing my HA so I have a HD setup. I have one good SD card of the 10’s of cards I have killed and it is now running my ssh honey pot on a pi 0 2.

  The mouse did not survive interrogation. Also mouse not pictured.

  I thought it was the huge heat sink that looks like it extends past the side plane of the cover. Reminds me of something I did with a CoolAir Cosmos tower. I mounted two 300 cfm fans over each CPU and took the side panel, neatly cut out the area around the fans, then 3d printed a scoop, with a slot for filtration, to fit on the side panel and allow the fans to breathe.

  Way back in the olden days, we had a hard drive with out any backups go bad. I determined that it was the circuit board. So I took a working drive and basically connected the bad driver’s platters to the working drive’s circuit board.

  It worked and I was able to back up the data and restore it on a new drive.

  I suspect you had a similar fun endeavor as me, where a media server with GPU passed through to a VM in Proxmox is also used as a gaming desktop. Admittedly I don’t use it often, so fiddling with it is almost as rewarding as using it when it works.

  Fitting a NAS on top of my cupboard. Been reconsidering putting it there though, may hide it under a table somewhere instead

  I’ve had a mouse burn my generator coils while going in while running

  I use e self made wood cabinet in the attic where also the PV inverter is located. I used Velcro to strip on the wall (brick wall) stuff like switch firewall etc, only to find those collapsed on the server itself every time. No matter which glue or adhesive i used.

  At the end, a strong unbranded Chinese double sided tape was better and still strong after all big western brand failed over time.

  Maybe a mix of heat and uneven surface was the culprit, who knows.
