TL;DR: The pool had the default cachefile=-, but Talos has no normal writable /etc/zfs location for zpool.cache. OpenZFS kept failing to write the cachefile and retrying SPA_ASYNC_CONFIG_UPDATE every 300 seconds. Setting zpool set cachefile=none hdds stopped the config_sync loop, and the drives stayed in standby past the old wake interval.

This was found with Codex/GPT-5.5 after about 2 hours of debugging, using a mix of tracing, disk-sector inspection, Talos debugging, and eventually reading the relevant OpenZFS source.

Full Story

I migrated a Kubernetes node from NixOS to Talos Linux. Same OpenZFS version: 2.4.1.

After the migration, HDDs in a ZFS pool would no lon

Is there a way to properly handle this?

In theory it shouldn't be that hard, a magic wrapper entity that directs on/off to the switch and color controls to the bulbs. It shouldn't let you turn off the bulbs themselves. I don't know if the existing helpers allow to do this easily though.

That said, there's probably some information lost in this (i.e. extra sensors in the bulbs), I would love to see something native or supported from HA.

Maybe it's already supported and I've completely missed it. For now I just did it "frontend side" with some card conditions.

What are you doing to manage smart bulbs+switches?

I've been trying to get a hold of one of these panels for my T480 but every seller I ask says they send "compatible" panels that in my experience are far, far from the real thing. I even got one with a broken EDID that blackscreens when i915 loads (works well on macos surprisingly, but with very low brightness and high power draw)

Does anybody have a link to an ebay/aliexpress/other listing for the real thing on hand?

(not really pipewire itself but an interaction with wireplumber/libcamera/the kernel, but pipewire is what triggers the problem)

As seen in https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2669 and https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4115

The camera's /dev/video file is kept open (without streaming), sadly causing the camera to be powered on what looks to be most devices. For some reason, this completely nullifies the soc power management on modern laptops and can result in increases from 3W to 8W at idle!

On Intel laptops it's a bit easier to debug because you can see the Cstates in powertop not going low but it also wrecks AMD ones.

I can't believe this

I was tempted to tag this labgore, but let's just go with help.

I am hitting a very suspicious ~6.4 gbps limit on my link between a dual port connectx-3 and a single port connectx-2, tested on iperf & speedtest. (Surprisingly speedtest runs sliiiightly faster)

Both are running at PCIe 2.0 x4 verified on lspci. That should be enough for some 16gbps theoretical max throughput after encoding losses, real world being less but still way above 10. Also, plenty of people have ran 10g cards over x4, no problems there.

My current theory is that the dual port card is simply splitting the bandwidth across both ports, 6.4 gbps is dangerously close to double the bw you get when running the single

I really liked opening the demo and doing some drifting. It was very unique and well made (pretty much no overlap with EV power and car games until now)

Full-er release coming soon?

I recently got <machine in title> but when it arrived I was extremely disappointed that the machine has been severely downgraded compared to the Intel L13 gen1 I had before in a few ways. The biggest is the trackpad, it has the same texture as the rest of the chassi (read: not good) and it's honestly awful. 2010s laptop grade.

It's common to swap the trackpad in other models for the glass ones from the x1, but this being a relatively unknown model in the already uncommon L13 line it's been hard to find jack shit information on the Internet about potential swap candidates.

And before anyone says so, I already use the trackpoint, this one actually has a usable one. Seems like I didn't l

This is usually the opposite of what people do, knowing how much power goes in&out using an amp meter would make this easier, but here we are.

My car has an API that returns the battery percentage. Through sheer Math™ available to a kid in school I get the rough kWh available.

I would like to add a panel to the UI that shows how many kWh I've charged today and how many I've spent going to random places

Doing this by eye is not hard, ie. just add all drops for discharge but no clue how to implement in HA.
