fp5 doesnt have headphone jack, every thread the jack jihadists cry about it even though fp explained it's design-wise convenient for them to move that to the usb-c port

My short unexciting story of replacing 2 power bricks with PoE:

I recently bought a D-Link DGS-1210-10P rev. B1 switch from ~2014 for $50. It has an 76W PoE power budget and supports up to PoE 802.3at (~25W).

(On the switch, OpenWrt is supported from rev. F1 - don't be stupid like me with the rev. B1)

I had some PoE-compliant devices in my homelab that I was powering with ordinary power bricks, but now that I got my switch, that had to change.

In total I was able to remove two power bricks:

  • My MikroTik RB5009 UG+S has a 802.3af PoE-in on eth1, so I removed its power brick and powered it with PoE instead
  • My UniFi AP 6 Lite supports 802.3af PoE-in, so I removed the unifi poe injector that I had and powered it directly from the switch

My homelab is rather small, so the only two remaining devices which I could swap are:

Looking at the amount of PoE splitters and how much people hate having too many power bricks, I was wondering of anybody is doing something unconventional with PoE at their homelab?

If you look at the PoE table at Wikipedia, you'll see that apart from the common 802.3af (~13W), 802.3at (25.50W), there is the beefier 802.3bt with 51W and 71.3W depending on the type. I was wondering if anybody has stories of playing with the higher power types?

... but given how many splitters there are:

  • PoE to USB-C (data+power) - guess it'd be cool for a dumb Home Assistant tablet - everything connected with 1 cable, but it's easier to just use regular USB-C and WiFi :P Could be also used for a wifi-less weird phone server. Can also just charge your phone

  • PoE to Eth+12V - limitless possibilities. There's a guy on reddit that connected a PoE to Eth+12V splitter to power his ISP modem. The PicoPSU also takes a 12V DC plug, so you can go PoE -> PoE to 12V+Eth splitter ->PicoPsu -> some low power computer -> burn down your house

  • Did some electrical engineer finally make a PoE solution for having so many power bricks when somebody has a SFF/TinyMiniMicro cluster? Those things are big.

You may be right - I do see my gigachad ex-coworker change companies every year. Guess I'm just more scared of having lots of short employments on my CV, or maybe I'm just locked into my way of thinking even if it doesn't make much sense.

I'm staying put till the interest rates start falling. I don't want to get hired (locked into a particular salary order of magnitude) when capitalism is cautious. I want to get hired when capitalism is stupid

bestie why do you have in your ? It doesn't point to an rss feed, unless your site is an rss feed in itself? would be kinda crazy though

should point to https://selfh.st/rss/ right?

Yeah. That's what I used to do when I started out.

The simplest thing to do is install Debian on the computer and create partitions. You have 4 HDDs and 2 SSDs so it'd be stupid to create 6 separate partitions for each drive.

See in the BIOS if your motherboard supports software RAID1, so you are protected against drive failure somewhat. This will allow you to get something barebones running that'll use at least 2 drives with redundancy. I assume the mobo RAID1 is stupid and only allows for max 2 drives, so the other drives will be just laying around useless. If that's the case, probably use the 2 SSDs first. I see other posters recommending higher orders of RAID, but I only have 2 HDDs so I never really delved into that :P Perhaps that's sound

With a system like that you could probably set up some small NFS for sharing your files by configuring it manually from the terminal.

Note that going with raw linux is "simpler" in the sense that it's perhaps easier to wrap your head around or tinker with, but TrueNAS or Unraid have GUIs that will allow you to create e.g. the mentioned NFS share with a few clicks, rather than having to do it from the terminal. Depends on what you're looking for. You could move up to TrueNAS or Unraid once you've played with raw Linux enough for example.


Once you have that,

I only ever dealt with ZFS and TrueNAS. ZFS will allow you to create a "partition" (pool in zfs terms) from many drives at the same time, so you'd be able to use more drives than just the two from RAID1.


The drives that you have are probably shitty SMR drives whose write speed dramatically slows down once you're writing to them for a longer time. Consider buying CMR drives in the future, or just going all-SSD if it fits your usecase. ZFS hates SMR drives.

Do you mean the offline translations? I think it may be the case that language support is handled by https://browser.mt/, Firefox just uses what they provide, see https://browser.mt/software

 

This is actually in the release notes for Firefox 118 here (https://www.mozilla.org/en-US/firefox/118.0/releasenotes/), but it also works on Firefox 115+ (as is mentioned in the bugzilla page).

Things that are still missing for me:

  • being able to send 1080p video. I have a 1080p 30fps webcam that can only send 1080p video when using Google Meet in chrome. On Firefox, only 720p is available.
  • support for call control devices. I have fancy headphones that can e.g. unmute you in Meet when you lower the microphone, but registering such a device with Meet is only available in chrome. See https://support.google.com/meet/answer/12562325?hl=en
 

Hello.

My setup is:

  • Lenovo M920q mini pc with Proxmox installed (this doesn't have IPMI, only vPRO and it's annoying me)
  • Fujitsu TX1320 M3 with TrueNAS Core installed - ZFS + RAID1 (this is a low-end "enterprise grade" server, and best thing - it has IPMI).

The Proxmox PC keeps all its CTs and 1 VM on the TrueNAS using iSCSI.

The idea behind my setup was that it felt nice that the TrueNAS would handle all the storage heavy lifting - ZFS, RAID etc., while the Proxmox mini PC would be a "compute-only" node that has a naked Proxmox install with some config.

The problem with that is if the TrueNAS machine loses power or is restarted, the Proxmox CTs/VMs switch their filesystem to read-only and stop responding to requests. This is because the iSCSI connection is interrupted. When the TrueNAS is back online, Proxmox doesn't make any attempt to restart the VMs/CTs - they'd still be broken.

It's annoying to me to have to VPN to the Proxmox web ui and wait 15 minutes until all the CTs/VMs are restarted and now again functioning on the "alive" iSCSI connection.

I was wondering what are my options here to remove the dependency chain?

I'm really into the idea of decomissioning the Proxmox node because I'm scared I won't be able to (over VPN) change the power state of the machine if something goes wrong, since it only has vPro and not iSCSI like the TrueNAS machine. By doing that, I'd consolidate the storage and the compute into the TrueNAS machine.

Options I can think of:

  1. Decomission the Proxmox node and move all Debian VMs/CTs to TrueNAS BSD jails. Is that even possible? Will all my Debian VMs work in BSD?
  2. Decomission the Proxmox node, switch TrueNAS Core to TrueNAS Scale and move CTs/VMs to TrueNAS Scale's Linux VMs
  3. Keep the Proxmox node and somehow figure out how to get Proxmox to refresh the CTs/VMs on iSCSI connection loss.
  4. Keep the Proxmox PC, but switch it to iESXI hoping that it handles the iSCSI failure more gracefully

EDIT: I didn't make it clear at first - TrueNAS stores more data than just VMs - documents, Linux ISOs (TM), photos, Syncthing
