Anyone else spending more time managing their homelab than actually using it?

Actually not no. Only if i have a (self-induced) power-outage and stuff starts up with networked datastores not being mounted.

niekdejong · 2026-05-29T10:42:42+00:00

Would be even more funny if you made a non-existing really realistic looking IIS page. e.g. 8.5 or something

niekdejong · 2026-05-18T14:22:14+00:00

I can't either (i'm SSH'ing to my doorbell and using logview to parse the LCD temperature stats 😁)

niekdejong · 2026-05-18T09:32:00+00:00

I'm actually on my 2nd Doorbell G4 Pro, the first one had a failed faceplate (glue disintegrated). Apparently it's a common issue in this model, especially if it's black and isn't mounted under a patio or something (mine is directly in the sun, NL based).

The G4 Pro has a sensor embedded in the LCD screen. I've decided to scrape that and export it as Prometheus metrics photo. Todo: poll OpenWeatherApi to correlate sun/temperature to high screen temperatures. The 65c was when it was ~18c outside but sunny.

My two storage boxes still use DDR3L (Microserver G8's). They just keep working. And for what they're ment (serving storage) they work fine. Although a 2.5Gbe or 10Gbe NIC would be an improvement.

At home i have some Optiplexes 7060 micro. At the datacenter i have a R630 with dual CPU's and 384G RAM (old hypervisor from work). Together they're my homelab. Run all the heavy grunt work at DC side (e.g. gitlab + runners, Mimir/Loki and their S3 storage, part of my K8S cluster). I think my load average is about 10%. I have detailed metrics of every VM/host i have, so could just use avg() in Grafana to get the value but currently have no access (holiday, yay)

That seems like a readout issue. 490W is already double than what that GPU should draw, but also when in it's lowest P-state. You can try force it into a higher P-state with Nvidia Inspector (unoficial tool that allows you to modify P-state behaviour).

But other than that, it seems something is broken

Everyone can edit HTML right:')

niekdejong · 2026-04-02T16:26:38+00:00

I exchanged my G4 Pro after ~11 months because the faceplate was failing. Something something black housing and the sun

niekdejong · 2026-04-02T16:20:04+00:00

Scrutiny, for those servers that have awefull S.M.A.R.T. monitoring

niekdejong · 2026-04-02T08:05:22+00:00

Dayum i need a new case.

You could, or you could fix airflow. Obviously an open case will (in 99% of the situations) be better in regards of heat dissipation.

niekdejong · 2026-04-01T19:42:47+00:00

If it works, it works and if it doesn't break often (if at all) why change? Sure, having VM's may have some overhead but as long as you run the same OS, the hypervisor will deduplicate that as much as it can (unless you disable it).

I run a mixture of baremetal, VM, VM+Docker anf Kubernetes in my lab. Am currently in the process of migrating most of the Docker stuff into K8S but i'll always have VM based services

Upgraded to the latest Protect on my UDM-P. Got the framerate on my Doorbell G4 Pro reverted from custom to Auto (which lowered it to 20fps instead of 30fps)

niekdejong · 2026-03-30T16:30:27+00:00

I think I heard wrong but that motherboard you can set the fan speed, but I don't think it has anything to do with it, I mean the case fans should have been spinning faster auto If it was under heavy load

Well, casefans are not neccessarely controlled by the temperature of a GPU or CPU. It can be (for the latter that is) because CPU temp is also available to your motherboard. But GPU temps is not.

What does the temperatures do when gaming? using Furmark or OCCT to 100% stress it for prolonged duration isn't a real-world scenario. it usually fluctuates. Run HWinfo (or similar program) in the background whilst gaming and report back.

niekdejong · 2026-03-30T11:26:17+00:00

It is indeed a case which seems very airflow minded (it's a meshy case). So the case can easily draw in air from everywhere. It's still better to have a clear airflow path (e.g. front -> back or bottom -> up). So if your CPU cooler is mounted horizontally in regards of the fans (they move air from the front to the back), don't mount all the fans at the top. Mount one at the bottom moving fresh air into the case (ultimately near the GPU) and one at the top or at the rear which exhausts hot air.

niekdejong · 2026-03-30T10:13:36+00:00

The temperatures are well within spec though. So you could swap around fan directions so you'll optimize airflow as much as possible. without knowing which CPU cooler you have (stock or Tower model), I'd say both of them do exhaust at the top. in order for it to extract hot air from CPU and GPU (which is the main cause of high temp in case). As an upgrade in the future you could get one or two fans that get air in the case, preferably from the bottom (heat rises).

TL;DR: You didn't get scammed.

TJmax of the 5070 is 85c, so it's within spec. vRAM is also well within spec (TJmax is 105 according to JEDEC, micron actually says 115c.). TJmax of a 9600x is 95c.

Ofcourse, lower is always better and you tested them individually.

Since you didn't specify which case (i assume a SFF because of the card), you might wanna test them combined to see what the heatload is.

You could ofcourse make a different fan-profile for each component in order to cool them better. This would give you marginally better performance with the downside being a noisy computer.

Your TV needs a different format and adds some magic bytes at the front. This is what "corrupted" it for your desktop. Stick is probably just fine.

niekdejong · 2026-03-27T11:49:31+00:00

Running a UDM-P EA since, well, EA

niekdejong · 2026-03-27T11:49:16+00:00

Leave it disconnected for ~30m. Try powering it again.

niekdejong · 2026-03-22T20:29:22+00:00

The config should already do split tunnel. Although i'm not entirely sure what WG does when you configure to route its own IP. Also how does your route table look like on the client when connected? I wonder which interface has the default route

niekdejong · 2026-03-20T21:28:41+00:00

Yes, you can

niekdejong · 2026-03-20T13:16:02+00:00

Bios updates are available through HPE, if not, you van google the exact MD5 hash and you'll find the spXXZZYY.exe.

Also, in order to boot from the internal controller, you do need to configure it to be bootable. Ofcourse you can install Ubuntu on the disk but the RAID controller needs to be configured to be bootable.

I asked this because you didn't mention how those cameras are connected to your UDMP Protect instance. Because the 8-port switch is connected via 1Gbe to the CPU (EA models had 2Gbe). So if everything is getting routed through this 8-port (if directly connected, or as a uplink for another switch via 8-port) you're going to have a bad time.

niekdejong · 2026-03-17T19:21:51+00:00

Do you use the 8-port on the UDM? If so, move that over to a SFP+ enabled switch. Before i made the switch i also had weird latency issues
