I will say, I wasn't 100% sure I'd like Unifi routers after setting a few up for family. Been running APs and Switches for years though

For Family it has been great, I can access their config remotely and diagnose any issues from the app or the web.

What I never liked was the routing rules. They just made no sense when coming from PFSense.

Seems the 9.0 update fixes a lot of this headache. I bought a UCG Max and replaced my PFSense router with only a few hours of config and tweaking.

I recently changed to a fritz box router and pinole has decided not to work anymore...

Anyone got any ideas? I can access the web interface but DND doesn't work from at least some of my devices...

I'll probs be changing my pis which host all my services to use k3s soon so will probs reinstall OS then, in case that makes any difference.

The new router did change my gateway btw, I think all the devices use the correct one now though.

I'm also just generally wondering what it is with Raspberry Pis and active cooling over the last two generations. For both the 4 and 5 models, the Pi foundation was saying "definitely do active cooling", and I think for both, the official case had an active cooler.

But I've been running both without active cooling without any issue at all. Sure, it takes a nice chunk of metal to achieve this, but it's not like it's a grotesque amount. The cooler doesn't even change the footprint.

After confirming that the NVMe performs exceptionally well, next I had to have a look at cooling. I started out a bit worried, because I was seeing about 50 C at complete idle.

I've now run "stress -c 4 -t 600", confirmed that the 4 CPUs stayed at their max 2.4 GHz the entire time. At the end of the run, the temp was at 78 C, which I find very acceptable. If any of these machines actually has to run at all-core full tilt for 10 minutes, something else is wrong anyway.

This is a typical FreshPorts daily database backup being rsync'd from AWS to the #homelab :

It just so happens the the output of pg_dump for the #PostgreSQL database more-or-less keeps the data in the same order each time. So the actual daily transfer SEEMS to be only the new data.

On disk, I rely upon #ZFS compression to do the disk savings for me. That compression also speeds up disk throughput - the CPU can uncompressed faster than the disk can provide the data.

In today's case, the amount copied down seems to be 360MB.

This speed-up by rsync, which recognizes what has and has not been transferred, is also why do not dump in compressed mode.

Success: I got frigate (home security camera NVR software) running in kubernetes, with GPU acceleration and a Coral TPU passed through to the pod. One less thing to manually manage ❤️

(thanks Intel for the intel-device-plugins stuff, it all JustWorked(tm))

The little display I bought for my Pi work already paid off. I had forgotten to put my SSH key on my new USB stick I use for the initial boot, and now I could just attach a keyboard and the screen and quickly fetch the key.

Thinking of refreshing my home server setup. Currently have NixOS on bare metal with a few things running directly there (Nextcloud, NFS server, some lesser things). I’m interested in learning kubernetes some more so I’m considering replacing NixOS with Proxmox then running Kubernetes across some Fedora CoreOS VMs (or some similar container focused OS). Is that a reasonable start? Do folks have any other suggestions for the base setup for #homelab #selfhosted #kubernetes ?

How many people working on their #homelab or #selfhosting journey for the long weekend? 🙋🏻‍♂️

Anyone with clustered compute and / or seperate storage want to try and convince me to make some purchases?

I’m debating whether I should run a centalised storage to move away from the servers as pets problem… each of my home servers is a unique snowflake, who need their own special and unique forms of attention (not documented)
