Oh hey. Today is Thursday, and you know what they say about Friday!
Don't wait to do it tomorrow when you can procrastinate even more and do it next week. 😄

After a year of running Nextcloud storage [1] at Hetzner, I noticed that I hardly use it. Sure, it's nice to have 1TB of storage at around €5/mo, but I simply haven't found a good way to make it part of my digital life. I will experiment with running my own Garage based S3 compatible storage [2] on one of my VPS machines instead (yes, my VPSs have unlimited network traffic).

Csináltam egy merészet.
Van egy Lenovo Yoga 11e tablet PC-m. De, Linux alatt egyszerűen sosem működött a tablet funkció.
Hat éve van nálam, de együtt tudtam ezzel élni, mert igazából nekem egy valóban kis laptop kellett utazásokhoz, ha ügyet kellett oldanom alapon.
Sosem használtam ki tabletként. Még Windows alatt sem. (Igaz, Windowst csak és kizárólag az ősöreg, de LifeTime Garmin Nuvi GPS-em frissítéséhez használok egyedül, mert nincs kedvem kerülő utat keresni rá.)
De, úgy voltam vele, hogy ha már van mindenféle CLI-s AI agent, akkor teszek egy próbát azzal is.
Oda adtam a Claude AI CLI agentjének sudo joggal együtt, hogy... oldja meg, ha tudja.
Dolgozik bőszen. És, igazából nem csak azért nem félek, hogy elront valamit, mert nincs semmi szenzitív azon a gépen és pikk-pakk újra telepítem és kész.
De, azért sem, mert egyszerűen egy netes keresést nem tud megcsinálni anélkül, hogy minden oldalra külön rá ne kérdezne, hogy engem-e....és ugyanez minden lépésnél itt is. Egyszerűen nem tudok normálisan gépelni, mert a másik monitoron az ssh-ban folyamatosna nyomkodnom kell az entert a jóváhagyások miatt.
Kíváncsi leszek, mi lesz a vége!

Nachdem nun alle AD‘s heute wieder laufen, kommt gleich die nächste Folge der nicht enden wollenden Serie: "Wie treiben wir Stefan zur Weißglut". Heutiges Thema: Plötzliche und unerklärliche Paketverluste bei IPsec-Tunneln über Weitverkehrsnetze.
Diese Woche ist echt der Wurm drin, es ist zum rückwärts essen.

Le Kernel Panic ? Même pas peur ! 😎
C'était juste Ventoy qui faisait son timide en mode Grub2. Une petite correction et hop, ce Lenovo L540 s'apprête à devenir un vrai nœud de test Proxmox VE. La virtualisation n'attend pas ! 🚀

Just received an email from my mail server administrator. They sent me a link to change my password because it's 'insecure'.
My mail admin is so efficient...
...hey, wait a minute... I AM my mail administrator! 🤦♂️

Today I want to thank the teams and communities behind
- #Forgejo [1]
- #Garage [2]
- #Kopia [3]for delivering (major) updates of their software (which if course is Open Source) that consistently JustWork™ in my experience, making the update process simple, reliable and, yes, fun! I know how hard that is and I tip my hat to all of you and many other projects that do the same.

TIL (Today I learned) that on #MacOS it is really easy (and fast) to create read-only filesystem snapshots with `tmutil` in a shell script so that I can make backups with #Kopia using those filesystem snapshots. Note: needs APFS as filesystem. Neat!
I updated my gist accordingly: https://codeberg.org/jwildeboer/gists/src/branch/main/2025/20251227-Kopia-Garage-Backup-Mac.md

Always good to see a well trained pit crew at work.
One of our suppliers sent us some merch. And @leece had a great idea...

⭐ COMPLIANCE TOOT
The Haunted Lighthouse just levelled up — full GDPR/ICO-ready data protection framework, DPIA, SAR forms, internal policies, the whole pack stitched together.
Self-hosting feels even better when the compliance goblins are fed and quiet.
Back to building… and hey, don’t forget the paperwork 😉 -
CW: Systems Administration, K8s, Storage.
At #work today I had an unexpectedly pleasant experience. With #kubernetes of all things.
I'm playing around with a sandpit #RKE2 cluster that I'm using to test how things are going to work when we need to deploy an actual working environment, and the matter of persistent storage came up.
A bit of poking around and I discovered #Longhorn. The requirements were trivial - all the required software was already present, just one service needed to be started. And so I installed it via #helm with just a handful of lines in the config.
And it just works. A fully distributed, clustered, read-write-many capable storage subsystem for Kubernetes, and it took me less than the time it is taking to write this to get it up and running.
I fired up a deployment that required multiple RWM PV's and ... it all just worked. I could even go into a management panel and see how the shards were distributed, and how busy everything was.
For a back-end all it needed was a filesystem on each node of the cluster, and even that could be managed with #LVM so it could be expanded at need.
Compared to the old in-tree VMWare CSI operator, this is a dream come true.

🚨 Stromausfall am Morgen, Admin-Frust am Abend:
Nach 10 Stunden Schrauben, Fluchen und Kaffee ist mein #Homelab endlich wieder bei 💯%.Der Crash:
⚡️ 2 #Proxmox-Nodes mit zerschossenen LVM-RAIDs
💥 Backup-Server wollte partout nicht startenDie Rettung:
🛠️ Cluster per Hand neu hochgezogen
📦 alle LXC-Container aus Backups wieder eingespieltHat Nerven gekostet, aber: mein Backup-Konzept hat den Ernstfall überlebt. ✅
Lesson learned: Stromausfälle sind der härteste Integrationstest. Ich brauche dringend eine #USV -

Predictive monitoring of disk usage can be fun.
One of our filesystems will run out of space in (checks watch) about 10^20 times the life of the universe.
And 312 days.
I'd better get onto that.

Today‘s SideQuest involves debugging an #OpenSSH connection via a containerized #jumphost where some jumps fail.
In that case sshd on the jumphost logs that it cannot resolve the target host. Checking on the host shows that it can correctly resolve that hostname and even successfully connect to it.
I guess somewhere between the container and the container host, some hostname resolutions seem to fail causing SSH jumping to fail.

Quarter 1 datacenter maintenance window. This time I'm migrating our primary NetApp cluster to a new pair of cluster interconnect switches.
