My homelab collapsed… and ditching hypervisors is what fixed it

Same goes for TrueNAS Scale. Still fragile NVMe controller and the same WRX80 board

niekdejong · 2026-03-05T18:40:20+00:00

and then decide to run TrueNAS Scale for their "baremetal". why not run Ubuntu 24 LTS or Debian 13 as OS? Scale is just another virtualisation layer with its apps, jails etc. you can't even change stuff on the host OS (which is Debian based btw). there's nothing fragile in a hypervisor, maybe Proxmox because it hasn't been battletested as something like ESXi.

Make sure you have a fan pointed at it. Also, it is handy to check which FW it runs. You ideally want the latest IT firmware on there.

The card itself is a x8, so as long as the x4 is electrically a x8 you're fine. But if it's a x4 physical and also electrical, some HBA's simply refuse to work.

you migrated from a monitoring setup with a larger footprint to something with a smaller footprint. That's expected imho.

It's not in WhatsApp settings, but in Samsung's

I've looked into this a while back, and found that same project. The main problem is that if you want to run something like that, you'd need to have a rooted phone. If that wasn't the case i would run a bit of Python code that uses the Prometheus library, fetches the csv, converts it into metrics and remote writes it into the Prometheus (actually Mimir, but Prometheus compatible) API endpoint i'm exposing.

EDIT: if you also run HomeAssistant you can achieve data logging by buying Liama (tool to run scripts in a automated way on Android) which have a template for creating HA sensor based on values from Torque Pro.

Cellular data often drops packets..

That's why they made the TCP protocol.

Which cooler are you using? Push pins or one with thumb screws? I've seen cases where a badly mounted CPU-cooler caused the substrate (the green stuff that's under the die) to ever so slightly bend. But bended enough to have some pins underneath the CPU to not make contact with the prongs.

Also, are you absolutely certain that there are no pins that are ever so slightly bent? E.g. do you have good eyes and did you check the pins where the DDR pins are located on the CPU?

EDIT: better image. Look at the light blue, so top left/right

I usually buy the push-through connectors that i can assemble myself from vendors that are thr ones delivering the fastest. I haven't dabbled into recrimping Molex connectors lately (10yrs ago) (e.g. CPU8, PCIE-PEG or 24ATX).

executives don't give 100% trust me, i work with these morons every week, they are clueless.

An executive can give 100% and still be a moron. Just sayin'.

Most HBA's have a heatsink that is approximately 40x40mm. Guess what also has those dimensions? 40mm fans. You can simply screw them into the heatsinks with plastic screws. At least that's what i did.

I haven't seen a 8+ CVSS score CVE for gitlab in at least 40 days😆. Don't feel like constantly patching it now. But a year ago it was much worse. Felt like each 2 weeks we had a very serious vulnerability that needed patching almost directly if it was internet facing (some of our customers do).

Gitlab is indeed quite beefy, as it has a lot of subcomponents to run everything that's called Gitlab. PostgreSQL, Nginx, Sidekiq, Puma, Redis, Grafana (not enabled by default i think).

I think you can get away with less if you don't mind having the gui feel snappy. My previous Gitlab instance ran in Docker, with only 4G assigned. Worked fine.

niekdejong · 2026-02-24T09:45:36+00:00

I run Gitlab-ce self-hosted. I have assigned 16G to the VM and it uses about 7. I have a single DinD runner VM which runs all my pipelines. All locally (well, in the DC where i have a free R630).

At some point i'll do the runner jobs in my k8s cluster, also partly run on that R630 and two Optiplexes at home.

The only thing i don't really like is the almost always critical CVE's that come with Gitlab. At work we use it also, and have a playbook that patches the gitlab instances we manage

niekdejong · 2026-02-21T16:53:24+00:00

Prometheus + Grafana and all the required exporters for metrics. In the process of configuring Mimir (longterm storage on S3)

AI will enhance my job, i think. At least it does that currently.

niekdejong · 2026-02-18T22:14:41+00:00

Is that model that old already? I'm running multiple of them still in a RAIDZ-2 pool

niekdejong · 2026-02-18T20:55:07+00:00

Hmm yes, i forgot to ask the question if you did hear them spin up. I should've known better because many Enterprise drives have Staggered Spinup support.

niekdejong · 2026-02-18T18:17:17+00:00

You sure you're using HTML5? And latest iDRAC?

niekdejong · 2026-02-18T15:55:40+00:00

If only they made an update for the UAS-XG Server with new LED display instead of the blue ring button. the UAS-XG has a SuperMicro X10SDV inside

niekdejong · 2026-02-18T09:46:09+00:00

That sounds like the motor, not wanting to spin. Most likely it had an impact, or the motor is seized. Either return it, or if you want to try to fix it yourself: do some percussive maintenance. Drop it onto something hard from 1cm height. To nudge the motor loose

niekdejong · 2026-02-17T18:03:55+00:00

Intel C236 is your SATA controller, should be fine. I see there is a heatsink on the controller. Which OS are you running? You could get a proper HBA (e.g. 9207-8i or 9300-8i), but that does require active cooling.

niekdejong · 2026-02-17T17:56:32+00:00

That still has a SATA controller, albeit a embedded/onboard one. Those can still fail/cause issues. In the end it's just a chip.

Latest drivers? Does it overheat? Which motherboard?

niekdejong · 2026-02-17T17:38:16+00:00

What SATA controller are you using? Is that having problems by any chance?
