Hey fellow sysadmin cosplay nerds, does anyone here use VyOS? I use VyOS as the main router for my home network and I just found out that a job for uploading backups to an off-site location is strangling my upstream bandwidth.

I want to create a QOS / traffic shaping policy to treat this as bulk traffic - take up as much bandwidth as available but give priority to all other traffic.

Is there a simple way to do this? I don't want to allocate a fixed bandwidth for it.

💝 Systems Hardware Friday 💝

Yet another afternoon stroll on over to the storage unit, locating spares and system parts from former projects. These will be allocated to three systems in my homelab (the rack at home this time):

1. Raptor Talos II box, needs a pair of Optane NVMe boot drives ✔️
2. Supermicro, EPYC Zen4, an additional Nvidia GPU for CUDA meta-port dev ✔️
3. Supermicro, E3/v6 Xeon, a second QAT 8960 for OpenZFS + OpenSSL comp/decomp/crypto offload ✔️
~. Napatech 4x10G SmartNIC, this is for my TRex load generators, so it's going to the colo ✔️

Should be a relaxing evening, mostly focused on the installs, and maybe some project planning too.

scaling back up now works too. I forgot about suspending CronJobs but that should be an easy add.

Now all I need to do is label some workloads - deployments , statefulsets, clusters etc… although I did get somewhat distracted tonight wondering if I can infer this from the Kubernetes API details. Ended up writing some code to draw network graphs with cytoscape and mermaid. Oops!

So, this turned out to be the HBA driver not liking IOMMU for whatever reason. Turning that off fixed everything.

I ordered yet another used SFF machine, this one with an i5-7500 and 16GB memory. I am going to install the HBA and 10gbit network cards, install TrueNAS, and then touch it as little as humanly possible.

Trying to set up OpenMediaVault on my HP EliteDesk 800 G4 SFF, but my aftermarket NVMe isn’t detected during install (tested with Debian, OMV, TrueNAS, Arch). BIOS sees it, but no OS does. Even after installing the OS on another PC, the EliteDesk won’t boot from it. Only the original NVMe works. Secure Boot is off. Anyone solved this?

For those that run a homelab with DNS and DHCP, are you using IPv6? I'm running BIND and debating if I need to configure IPv6 just to future-proof myself. I'm not seeing any issues, at least any that I notice.

Also, I know little about IPv6, so I admit I need to do some learning.

My #homelab disk array went pear shaped again last night when I rebooted the host. No idea what's really going on. I've replaced the disk shelf PSUs, the HBA, and the memory in the host. I sort of suspect driver or kernel issues?

At this point I feel like my options are to get another SFF machine, throw stock Debian on it, and hook it to the shelf to see if that helps, or build myself a machine physically large enough to hold all the drives and connect them directly to the motherboard.

As a diagnostic step I'm going to pave the boot drive with Debian and see if anything works.

Decision was made. I’ll move my #homelab domains from #Cloudflare to #Infomaniak. One by one upon reaching each renewal deadline. #Cloudflare is a little bit cheaper, but has a lot of stuff I’m not using and/or don’t want. #Infomaniak gives limited free email service with each domain and is #european. Also #infomaniak feels more like a good old web hosting with a modern UI, good documentation and additional perks. I like it so far.
The only #Cloudflare thing I’ll miss is an almost instant DNS records update considering how many ISPs and services rely on 1.1.1.1.

I see a lot of books/tutorials about mysql. Can I use those to understand mariadb? It seems that I can, it also seems that mariadb is preferred to mysql.

If anyone has any good sources to learn more about databases, I would love to hear them. I am just getting started with them.

I'll mainly be using it to hold text and numbers.

Getting sick of my @forgejo instance just getting constantly AI crawled... Looks like Claude and AmazonBot at the exact moment, but it varies all the time.

What's the move here? I would go @Codeberg but I like my private repos and I have a couple big containers that I publish just for myself...

It's just for me, so I guess I could pull it behind the VPN, but not everything that touches it is actually inside the network...

It's as good a time as any to convert the house almost completely over to #IPv6 while my partner is away... And she'll be none the wiser. 😄

Glad I've become a bit of a neo-Luddite and reduced the number of home IP devices over the years from ~20+ down to about 5.

I've been through 3-4 aborted Enterprise IPv6 migrations in the last 25 years. At least with this project, I can happily say "Mission Accomplished"!!
