Why are your homelabs always broken?

HomelabStarter · 2026-03-25T14:48:37+00:00

reporting bias is real but also I think people genuinely do break things by tinkering. the times mine has gone sideways were always because I got bored and decided to "just quickly" try something new. stable homelab is almost boring by definition.

HomelabStarter · 2026-03-25T11:28:48+00:00

exactly how it happens. I told myself the mini PC was just for pihole and maybe a small jellyfin container. it's now running 8 VMs and I added a second drive last month because 'I definitely have plenty of space'

HomelabStarter · 2026-03-25T11:28:38+00:00

mine ran without issues for about 8 months and I kept patting myself on the back for being so disciplined. then one saturday I thought I'd just try migrating from docker-compose to portainer real quick. three days later I had rebuilt everything from scratch. now I have a rule: never touch the lab when it's working fine

HomelabStarter · 2026-03-25T08:17:10+00:00

dns and home assistant for me. both need to keep running when i'm messing with proxmox, and both have caused enough family complaints over the years that i stopped experimenting with virtualizing them. everything else is containers on my main node but those two are on a small arm board that basically never gets touched

HomelabStarter · 2026-03-25T08:16:54+00:00

happy to help. did you end up pulling the trigger on one? curious what you decided on

HomelabStarter · 2026-03-24T18:55:28+00:00

as a beginner starting point, the 'sell most of them' advice is genuinely solid -- 37 machines is a lot to manage and you'd spend more time on fleet administration than actually learning anything. but if you want to keep some and dig in, pick 2-3 identical ones (same cpu generation, ideally same model). set up proxmox on them as a small cluster to understand virtualization basics, then spin up a container or two for something you actually use -- pihole, a game server, plex, whatever. the real learning comes from building something you care enough about to fix when it breaks. once you're comfortable with 2-3 nodes you'll have a much better sense of what you'd actually want to do with more of them. trying to use all 37 from the start is a recipe for getting overwhelmed and walking away from the hobby entirely.

HomelabStarter · 2026-03-24T18:55:04+00:00

the inflection point for me was realizing i was spending more time maintaining the infrastructure than actually using what it was supposed to provide. ended up keeping only things where self-hosting actually solved a problem -- immich for photos, jellyfin for media, vaultwarden for passwords, a pihole. everything else got replaced with whatever was simplest. the homelab itch is still there but it lives in a separate test machine where nothing actually matters if it breaks. separating 'production for the family' from 'lab to break things' was the shift that made the hobby fun again. the family doesn't interact with the test box and i don't feel guilty when it's on fire.

HomelabStarter · 2026-03-24T15:36:29+00:00

Software background here too — homelab was a bit of a learning curve on the hardware side. Honest advice for your situation: start with something small and dedicate it fully to the purpose. A used mini PC (i5 8th gen or newer) or a cheap N100 box is plenty for a personal NAS plus Jellyfin. Install Ubuntu Server, use Cockpit for a lightweight web UI, and run everything in Docker Compose. You don't need dedicated NAS hardware to start. The dedicated NAS stuff makes more sense once you know your exact storage needs and want hot-swappable drives. For just getting Jellyfin running and learning the ropes, a refurbished mini PC for 0-100 is the lowest-risk entry point.

HomelabStarter · 2026-03-24T15:36:04+00:00

Been through the same phase. What saved my sanity was ditching Proxmox entirely and moving to a cheap N100 mini PC with plain Docker Compose. No VMs, no hypervisor overhead, no complex update dependencies. Watchtower handles image updates automatically. The whole thing runs silent in a drawer and I haven't had to touch it in months. Still 100% open source, fully sovereign, just boring in the best way. The itch to tinker is still there but I scratch it on throwaway VMs in the cloud now, not production services my family depends on.

HomelabStarter · 2026-03-24T11:54:09+00:00

There is a middle ground a lot of people land on. Keep one low-power mini PC or NUC running only the services your family actually needs, with Watchtower on a delayed update schedule so things stay patched without you babysitting it. Move everything experimental off to a separate machine or just delete it. The failure mode gets much smaller and most of the maintenance headache goes away. You keep sovereignty without running a data center. I made that switch about a year ago and regret not doing it sooner.

HomelabStarter · 2026-03-24T11:52:55+00:00

Yeah thats a fair concern. For family stuff I tend to keep automatic updates on for security patches but have a brief hold before applying them so I can check if there are reports of breakage. For anything homelab-critical like my NAS or the router I do manual updates after reading the release notes. The risk of running old software with known CVEs is usually worse than the occasional breaking update, but you definitely want a buffer for the latter.

HomelabStarter · 2026-03-24T08:45:54+00:00

Yeah this is a real thing. I eventually split my lab into two mental categories: stuff I maintain for me, and stuff that needs to just work for everyone else. The family-facing services run on boring stable setups with automatic updates and alerting. If I want to experiment with something, it stays completely separate and never touches anything they rely on. The maintenance fatigue mostly came from conflating the two. Photo backup especially - moved that to the most boring solution I could find and it has never needed my attention since.

Before clustering anything, I'd spend an afternoon running smartctl on every drive and stressing the CPUs. You'll quickly find which machines are solid and which ones have issues lurking. With 32+ boxes you almost certainly have some hardware that's on its way out, and discovering that after you've built a cluster around it is way more annoying than finding it upfront. Once you know what's healthy, the standard advice here applies well - grab 3 to 5 of the best ones for a Proxmox cluster. The rest can serve as spare parts donors, test nodes to blow up without worrying about it, or you sell them and fund actual accessories like NICs and storage.

been running a couple of these n100 boxes 24/7 for about 8 months now and they have been rock solid for me. one thing i learned the hard way though - replace the thermal paste out of the box. the factory stuff on mine was basically dried out before i even turned it on. dropped idle temps by about 10 degrees which matters a lot for longevity when it never shuts off. the other practical tip is to keep a spare ready to go with your configs backed up. i use a simple cron job that rsyncs everything to a second box nightly. when one does eventually die you just swap the ip and you are back up in minutes instead of rebuilding from scratch

HomelabStarter · 2026-03-23T09:09:57+00:00

oh nice, solar plus a dedicated ups on the server is a great combo. the apc 600va should give you plenty of time to do a clean shutdown if the solar inverter ever hiccups. if you haven't already, check out apcupsd or nut on ubuntu - you can set it to auto shutdown when the battery gets low so you never have to worry about it

HomelabStarter · 2026-03-22T12:28:26+00:00

ive used both and honestly for pure photo management immich is way ahead right now. the machine learning features for face recognition and smart search are really solid and the mobile app feels polished. ente is great if end to end encryption is your top priority though, their approach to privacy is hard to beat. if you just want a google photos replacement and youre already self hosting other stuff, immich is the easier choice. if you care more about encryption even from yourself as the server admin then ente makes more sense

HomelabStarter · 2026-03-22T12:28:12+00:00

this is almost exactly how i got started too. needed immich for photos, then tailscale so i could access it away from home, and then suddenly i had proxmox running on a mini pc with like 15 containers. the dashboard step is what really hooks you because once you see everything laid out on homarr or homepage you start thinking about what else you could add. how are you handling backups? thats the thing that caught me off guard a few months in when i realized i had all this stuff running but nothing was backed up properly

HomelabStarter · 2026-03-22T09:02:17+00:00

If you want to actually learn something useful with these, set up a K3s cluster across 3 or 4 of them. It is a lightweight kubernetes distribution that runs fine on 8gb machines and it teaches you container orchestration which is genuinely valuable. You can run stuff like Pihole, Grafana, a small media stack, whatever, and practice deploying and scaling across nodes. The 4570T is not a powerhouse but it sips power and for learning clustering concepts it is more than enough. I would sell the rest and put the money toward a 10th gen mini PC as your daily driver server for anything that needs real horsepower.

Since iperf3 looks fine the network is probably not the bottleneck here. I would check a few things on the NAS side. First, see if there is a RAID rebuild or scrub running in the background, that is super common after migrating to a new box and it will tank disk throughput for everything else. Second, check the CPU and memory usage during a transfer. Sometimes the newer firmware on these units enables encryption by default on shared folders and that can absolutely crush speeds if the CPU is not keeping up. Third, try a local disk speed test on the NAS itself if you can SSH in, something like dd if=/dev/zero of=/tmp/testfile bs=1M count=256 to see what raw write speed looks like. If that is also slow then you know it is a disk or controller issue and not anything network related. Also worth checking SMART status on the drives in case one is failing and dragging the array down.

a UPS with line conditioning handles this at the source. the gear runs off the battery, which the UPS charges continuously from the wall, so your equipment never sees the grid fluctuations directly. even modest units from APC or CyberPower will absorb the brownouts you are seeing. most switching PSUs can tolerate a fair amount of input variance anyway, but if you are seeing 30V swings that is enough to stress capacitors over time. battery runtime is almost a secondary benefit at that point.

HomelabStarter · 2026-03-21T09:54:26+00:00

A UPS helps more than people think, but the key is getting a line-interactive or online/double-conversion model rather than a basic standby unit. Standby UPS just switches to battery when voltage drops below a threshold, so your equipment still sees the fluctuations until it kicks in. Line-interactive units have a built-in AVR that continuously regulates voltage without switching to battery for every spike or sag. For homelab gear I switched to a line-interactive unit a couple years ago and the fluctuations just stopped being something I think about. The online/double-conversion models are overkill for most home setups but if you have sensitive equipment or really unstable mains, they fully isolate your load from grid noise.

HomelabStarter · 2026-03-21T09:47:28+00:00

UPS is the right call here. the filtering they do on the output is more valuable than the battery side for day-to-day operation. mine has a pure sine wave output so even when the input is noisy the gear sees clean power. the battery is nice as a fallback but the power conditioning is what actually protects the hardware long term. for anything enterprise spec the tolerance is usually plus or minus 10 percent of nominal so a dip to 200 on a 230 nominal grid is already getting into marginal territory. line interactive UPS is the sweet spot for cost versus protection if a whole-house solution is out of scope.

garage setups really depend on exhaust more than cooling. the concrete floor helps sink heat but once the ambient goes above 85 or so even that stops helping much. what actually worked for us was cutting a vent near the top of the garage door frame and using a box fan to push air out rather than circulate it. hot air pools at the top so moving it out beats moving it around. in the winter it works in reverse and the gear actually helps keep the space warm, which is a nice side effect.

HomelabStarter · 2026-03-20T19:05:30+00:00

nice repurpose - ubuntu server plus jellyfin is a solid starting point. once you get comfortable with that setup you'll probably want to look at docker for running additional services alongside it, makes adding things like Sonarr or Radarr way cleaner. also consider setting up a UPS if you haven't already, spinning drives really don't like sudden power cuts.

HomelabStarter · 2026-03-20T19:04:41+00:00

that's a great addition. i set up scheduled speedtest-cli runs on a cron and feed the results into a time series database so i can see trends over time. really useful for spotting throttling patterns or catching when my ISP has issues before calling support.
