Been working on a project for a bit with AI due to limited hands on time.

Essentially a simulated ship running in GoDot emulating different CPU types. With a fully functional Debian instance in the ship.

The server side runs runs in my k8s cluster, with the universe being run from there and easily scalable.

Not something that will ever be released, but for fun for me.

J’ai fini par faire cohabiter K3s et Docker Compose dans mon homelab. Ce n’est pas une migration laissée en plan : je garde les deux.

Compose reste très bien sur une seule machine. K3s devient intéressant pour apprendre Kubernetes ou préparer l’ajout d’autres nœuds.

Pour les services avec des données, le plus compliqué reste le stockage et les sauvegardes. Kubernetes ne règle pas ça tout seul.

My homelab's real bottleneck has never been CPU or storage. It's how much noise, heat, and power draw the people I live with will quietly put up with.

I've made hardware choices based on which shelf sits far enough from the bedroom. Quieter fans won out over faster ones. The rack lives where it lives because that corner is the one that never drew a complaint.

You can spec the perfect setup on paper. It still has to pass the person who has to live next to it.

Question to the people who fully (or most of the time) work from home: how do you keep going with your personal projects after work? Do you have another computer on a different part of the house, or do you roam with your laptop, or you don't care and you just sit inside the same four walls most of your day and evening? If something else, please comment.

I personally do everything in one space, so there are some periods of time when my projects or my home lab maintenance lag behind, simply because I don't want to sit in that office anymore. How about you?

THE DGX SPARK WAS NEVER SUPPOSED TO SET YOU FREE

Listen to me.

128GB WAS NOT A TECHNICAL LIMIT.

It was a containment boundary.

You think NVIDIA accidentally built a tiny Blackwell supercomputer with 200Gb networking and then somehow stumbled into exactly enough memory to make every ambitious local-AI workload tantalizingly miserable?

COME ON.

64GB would've been obviously useless.

256GB would've been dangerous.

Because at 256GB, normal people start getting ideas.

Suddenly you're running giant quantized models comfortably. Fine-tuning gets breathing room. Long contexts stop being a hostage negotiation. You start running multiple models.

Then somebody asks the forbidden question:

"Why the hell am I renting GPUs?"

AND THAT QUESTION CANNOT BE ALLOWED TO PROPAGATE.

So they gave us 128GB.

Not enough to escape.

Enough to see the fence.

And look at the networking!

WHY DOES THE CUTE LITTLE DESKTOP AI BOX HAVE 200 GIGABIT CONNECTX?!

Because the second you smash into the memory ceiling, NVIDIA already has the solution:

BUY ANOTHER SPARK.

Now you've got 256GB!

Need more?

BUY FOUR.

Congratulations!

You wanted a desktop computer and somehow NVIDIA convinced you to build a FUCKING CLUSTER.

And if you're sitting there thinking:

"Surely NVIDIA couldn't possibly put dramatically more coherent memory into a local workstation..."

WRONG.

DGX STATION: 748GB.

THE MEMORY EXISTS.

THE TECHNOLOGY EXISTS.

THEY KNOW YOU WANT IT.

THEY JUST PUT IT IN THE NEXT ROOM AND CHARGE ADMISSION.

This isn't product segmentation.

THIS IS COMPUTATIONAL EDGING.

Spark lets you load the model.

Lets you run the model.

Lets you fine-tune just enough of the model.

Lets you build an entire workflow around the model.

And precisely when you've invested three weekends, fourteen containers, two broken CUDA environments and the remaining fragments of your marriage:

OOM

That's not an error message.

THAT'S THE SALES DEPARTMENT KNOCKING.

And NVIDIA TELLS YOU THE PLAN!

Develop locally.

Prototype locally.

Validate locally.

Then move the serious work onto larger NVIDIA infrastructure.

MY BROTHER IN CUDA,

THAT ISN'T A WORKFLOW.

THAT IS A FUNNEL.

Spark isn't supposed to replace the data center.

Spark is the free sample outside the data center.

The 128GB isn't there because NVIDIA couldn't give you 256.

It's there because 256GB might have been enough.

And enough is the most dangerous word in NVIDIA's entire business model.

So remember:

64GB = nobody buys it.

128GB = everybody wants more.

256GB = people start getting independent.

748GB = PLEASE SEE YOUR NVIDIA SALES REPRESENTATIVE.

WAKE UP.

REMOVE THE THERMAL PASTE FROM YOUR THIRD EYE.

ALIGN YOUR CUDA CHAKRAS.

WRAP YOUR CONNECTX CABLES IN TIN FOIL.

THE DGX SPARK ISN'T A PERSONAL AI SUPERCOMPUTER.

IT'S A 128GB GATEWAY DRUG TO THE DATA CENTER.

#JetKVM is powered and ready for my #vacation away from my #homelab. Just in case.

Every homelab project I over-engineered is dead now. The HA cluster, the fancy monitoring stack, the self-healing setup I burned a weekend on. Killed by their own complexity, or by me getting tired of feeding them.

The things still running years later are the ones I'm a little embarrassed by. A cron job. A single container with a run command I typed by hand and never saved. A Pi taped behind a shelf.

The stuff you're proud of and the stuff that lasts are almost never the same thing.

I need to organize my #homelab #backup documentation before I introduce a new backup method. Some clean representation of what when, where and how.

I’m thinking that rsync is not sufficient for important large data backups. Even if I’m rsyncing the data away to the Hetzner Storage Box.
I need something more advanced with deduplication and so on. I tried #borgbackup in the past, and that thing was absolutely not user-friendly. It was rather user-hostile.
Now, #SelfHosted community has #Duplicati and #Duplicacy? Does someone use one? Any recommendations?

Radxa ROCK 5 ITX booting GRUB -> ZFSBootMenu -> Debian with native encrypted and mirrored ZFS root filesystem on dual SATA SSDs.

Single passphrase entry.

The last piece was adding rootdelay=15 to the kernel command line since the SATA controller is a little slow to initialize.

I've been spending a lot of my time building software with #FreeBSD's Ports system. Sure, I could just install packages but Ports is an incredible learning experience. Poudriere especially.

It's definitely not as straightforward as initially thought and builds will fail for various reasons, but....I haven't had this much fun troubleshooting in a long time.

One question I do have for the folks in the room is:

When it comes to the frequency of pulling down new versions of the Ports tree via git pull, how frequently do people recommend?

The Handbook does not mention it and it's definitely an important operations-related task.

#RunBSD #homelab #learning #tech #unix #BSD

I have Debian with ZFS native encrypted rootfs booting on a Radxa ROCK 5 ITX. The only remaining issue is that the passphrase isn't passed from ZFSBootMenu to Debian's initramfs, so it has to be entered twice. Should be fixable.

#embedded #homelab #linux #zfs

I'm morally obligated to write up a blog post about chain booting the Radxa ROCK 5 ITX with a zfs native encrypted root filesystem via EDK2 -> Grub 2 EFI -> ZFSBootMenu, aren't I?

I tried connecting the dead Intel D3-S4610 480GB SSD I have into my new USB bridge. Power light turns on, the turns right back off.

It was working fine six months ago, not sure what happened to it.

My multimeter doesn't show a short on the external pins, I made a brief attempt at board level diagnostics and then decided it wasn't worth the effort.

Free to anyone willing to pick it up around Liverpool Street station in London.

#homelab

I bought four Intel D3-S4610 480GB SSDs on eBay.

Three from some dude for £55 each, and one from a refurbisher for £70.

The £55 drives were pretty much prestine, the £70 drive had logged over three petabytes of writes and showed 27% lifetime remaining.

Also, I now have a USB-C SATA bridge that can issue ATA Security commands.

Stepping Up to Self-Hosting

I got into Android at the beginning, with a pre-order of the T-Mobile G1, because I never liked the proprietary-everything ecosystem Apple built with the iPhone. I was geniunely excited about the potential of an open-source mobile OS, even if it was coming from a billionaire-owned tech giant. I rooted my Android phones and flashed custom ROMs to them for years. It was a blast. Then Google and Samsung started closing out that scene, and I lost the excitement that had drawn me in at the beginning. That sense of potential evaporated.

Years later, I found myself drawn back to open-source stuffs when I stumbled into the Fediverse. I love the sense of possiblity that pervades the Fediverse and FOSS projects in general. I've been hopping around for a few years now, trying different instaces running different software, and it's this Fedi project—littleFedi—that made me feel like now is the time for me to try my hand at hosting my own stuff. I know the code isn't ready for me yet, but that's okay because I need time to research self-hosting options. I'm hoping the Fedi can help with some of that.

I'm not a programmer or a techie—perhaps call me an advanced user. From my reading, I feel confident that I could manage a self-hosting from a VPS. Honestly, though, I'd prefer my own hardware at home. The problem is that there are a lot of options, and I'm feeling a bit overwhelmed. I thought I'd share what I want from my hardware, at minimum, and see if some helpful Fedizens have suggestions. So here's what I want:

• A Nextcloud instance for file storage. I have hundreds of gigabytes of music, videos, and photos, and I want a place to store all of that in the cloud.
• A chat client. Maybe Nextcloud Talk, but I'm also thinking about a Matrix server. Just haven't read much about self-hosting Matrix yet.
• A Fediverse client. I had been thinking of WordPress with the ActivityPub plugin because I like having the option to write long blog posts as well as short status posts; however, I'm now thinking that I'll run a littleFedi instance once the code is published.
• Email. Because if I'm going to be hosting my own cloud storage, chat, and social media, I might as well take care of my own email as well.

I have limited physical space in my cabin out here in Bumblefuck, so I've been looking at mini PCs. I see that Nextcloud even sells some with Nextcloud preconfigured, but I'm not sure any of those are for me. I prefer Linux, but I'm comfortable with installing Linux on a machine that ships with Windows. (Done that with several of my old laptops.) I'll consider a Mac mini if y'all recommend one, but it's been a decade-plus since I've messed around with macOS.

I won't be making a quick decision here, so as long as this blog is still published without an update, I'm still looking for options and I would still appreciate tips, suggestions, and stories about your own self-hosting adventures.

Be good to yourself, and be good to others 🫶

Genau: Sinnfreie Statusseiten mit eigenem Design bauen. 😄

Da sich unser tolles Werkzeug #UptimeKuma ja so *hervorragend* designen lässt (Ja! Das war dezente Kritik. Dennoch: Danke für dieses tolle Stück Software! ;) - musste ich für die Optik mit der API ran.

Für zwei von drei Welten gibt es nun kleine eigene Statusseiten die zwar schon bestanden und auch weiterhin bleiben, aber eben im eigenem Kuma-Design.
Beide greifen auf die API ihres jeweiligen Origins zu:

🌐 #AWsite – mit eigener Subdomain:
https://status.weindl.biz

🌐 #FEROX – bekommt einen Pfad:

Einzig #AWiT bleibt vorerst beim Kuma-Standarddesign. AWiT bekommt aber in absehbarer Zeit ein komplettes Redesign, sobald die Vereinsgründung abgeschlossen ist.

Upgraded all my PostgreSQL 17 containers to 18 this morning #selfhosting #homelab #postgresql

One of my repositories on my self-hosted forgejo instance is being hit by Anthropic crawlers. They have an infinite loop to download a tar archive of the repository leading to somewhat like 200GB of archives. My backup process struggled to send snapshots remotely on my 6 Mbps upload line. I've made the repository private. And now I'm considering putting Anubis in front of the service.

#forgejo #anubis #ai #anthropic #selfhosting #homelab

My final approach to provision vms in the cloud and in my homelab now is:

• create the machine with a temporary ssh key
• add it to the Ansible inventory
• run Ansible against it in CI to install and configure salt-minion
• manually accept the salt key on the salt-master
• have salt-master apply the default config and replace the ssh keys

This saves me about 10 to 15m of manual configuration each time.

and this is the data ownership migration hook:

New #homelab feature:

I already had a security extension that set reasonable defaults for things like capabilities, tmpfs, pid/memory/cpu limits, etc. Before today, it set a fixed non-root uid:gid.

Now it calculates a deterministic pair using the same algorithm that generates IPv6 subnets and addresses, unless there's already an override.

It also automatically reconciles ownership in existing bind mount volumes to the new uid:gid, so I don't have to futz with anything during the deploy.

First impressions with Poudriere? Wow, this makes life so much easier. In the context of #IT #Operations, whoa...this goes well beyond just automating builds in dedicated jails, Poudriere now becomes the enterprise package management repo system.

I've been running my personal "links" page on top of Azure Application Services, which is basically a "Docker Compose on steroids".

This now has been upgraded to a VM running a custom-built Fedora bootc image (still in Azure). Fully manageable via GitOps with build pipelines and auto updates. Part of the pipeline is in my private Forgejo, and part is in public GitHub.

At some point I intend to post a template so you can replicate, along with a blog post on how to do it. This was also a chance to upscale my Forgejo runners, so I'll blog about that as well.

What's the point of having a home lab designed to solve problems but you end up having more problems than the ones that it should solve?

Decision made to uninstall one of the three storage servers at my in-laws. No matter how much electricity it costs, even if it costs a kebab a year, if it seems useless, they will always challenge the cost.

I'm pretty sure that the second storage server at my dad's will retire too for the same reason anytime soon.

I do not remember who recommended this to me, but let me recommend it to you.

This USB cable tester is very convenient to keep around. It will help you clarify any doubts you might have as to whether you have the wrong cable (USB 2/3/4) or just a bad one (just power).

Sadly it also helped me realize that all my spare USB cables are either 2.0 or power only. But okay, knowing is half the battle.

Does anyone have a recommendation for a Raspberry Pi 4 (specifically 4) HAT that can provide PoE *and* a full size NVME at the same time?

I have the official PoE HAT, but it doesn't provide enough power for an NVME connected via USB enclosure, and I would prefer to keep the PoE if possible (since I can use it as "poor-man's remote reboot").

And, in case you're wondering: I do have a PoE splitter dongle sitting idle in a cabinet, but I would prefer to avoid it because of the Pi's USB-C position. But I would move it around if there isn't a better way.

In 2024, I went to LA to give a talk about how I made my own cloud storage to backup my pictures, documents, but also the ones of my family. I have chosen Seafile but it didn't work as expected. It filled the disk of my dad. At that time, I was suggested to try Nextcloud.

Today's the day, after 2 years. I've set up the latest docker image, spawned a PostgreSQL database, created some users, directories and uploaded files. Everything went well.

Then I started to install the mobile app to sync pictures from my phone and the desktop app to sync my documents. And things got spicy. The mobile app has uploaded 1200 files in... a day, with hundreds of errors I had to dismiss. The desktop app has uploaded 6 files in an afternoon, out of 1700, then stopped with failure. Why can't we have the performance of rsync with the user fiendly interface of nextcloud?

@homelab Does anyone of you fine people have experience with a self-hosted k3s cluster and nodes on different networks? I'm wondering whether it's a good idea to consolidate all the services I run at home with the stuff I have on a VPS this way.

Neuer Artikel im Blog.

„Gibt's für podman eigentlich auch was Grafisches?" Ja, gibt es. Nur läuft die GUI da, wo der server gar nicht ist.

podman desktop sitzt auf dem Notebook, die container hängen per SSH am server. Es zeigt übrigens auch docker-container an – docker desktop umgekehrt keine podman-engine. Die Kompatibilität ist eine Einbahnstraße.

Wer pod automatisieren gelesen hat, weiß sofort, welchen Socket er braucht.

I’m thinking about turning my #VPS in a #Proxmox node and adding it to my #homelab cluster. All other nodes are at my home. They will communicate through #WireGaurd. How bad is this idea? Anyone tried this?

Made what feels like a meaningful security improvement to my #homelab tonight.

I run a little cron thing called Ofelia, but because it's an off the shelf container and I want to bundle scripts that do weird things, I was mounting the docker socket into Ofelia so it could invoke scripts in a generic cron-hook container.

I wanted to start having Forgejo webhooks trigger the same cron jobs but didn't want to mount the docker socket into yet another container.

So:

- Add a little daemon in the cron-hook container that has a statically defined config file with all the job scripts mapped to IDs and listens on two Unix sockets, one for all jobs and one just for jobs that opt into webhooks

- another little daemon that receives Forgejo webhooks and maps them to job ids and calling into cron-hooks

- Ofelia collapsed to just calling into cron-hooks, losing docker socket access.

Now just four things have docker socket access: cron-hook, watchtower, vector (log shipping) and cadvisor (monitoring).

Any suggestions on which BSD OS I should go for?

Next project: The Cover-up

Homelab is sitting on the two lower shelves of an IKEA BESTÅ TV bench.

I'm going to make two wooden frames and cover them with black fabric, like a speaker front.

First iteration is just to balance/press them in place, next iteration will use some sort of magnetic or velcro fixture

#SysAdmin #HomeLab #SelfHosting

"Homelabs" are where people set up and run their own physical servers at home. It's the most difficult way to self-host services, but also gives you total control over the server.

If you've got a homelab or are interested, you can follow one (or both) of the homelab discussion groups:

🌱 !@homelab (in English)

🌱 !@homelab_de (in German)

After you follow, the group's posts will start showing up in your timeline. You can post to a group by mentioning it in your own posts.

So, if I can't trust an IoT device, a camera, a printer, any smart device that calls home, and now some brands of TV and set-top boxes, what is left to trust in my network? Should I just have one VLAN per device type and not let anyone talk to anyone?

This is getting out of hand, and is very tiring.

Ps.: I'm not asking for technical advice, this is just me venting.

Post Originaly from https://bsky.app/profile/fjox.win/post/3mofs2frbvs2v at 2026 06 16

my server had been down for like 5 days now. Now im stuck on this stupid place and don't even have acces to my nas. Then I found out I spend the last day and a half copying the wrong drive with ddrescue. Im soo done with this shit. I have decade old hard drives but ask a ssd to do more then 3 years hell no. I want a server that could run forever if electricity is provided. Ssds make it impossible. 3 months of 15 vms that probably didn't even do 500gb per day in total killed a drive that supposed to have a rw capacity of 2400 tb. Also I hate bluesky with its stupid twitter like post limit of 500. My mastodon had a limit of 65536. You could write a small book with that. And now that I have to copy shit with ddrescue again but instead of getting the same or better performance since its a ssd copying to a USB harddrive compared to a USB harddrive to the same USB harddrive its 30 times slower at peak. And that USB harddrive is 1tb bigger. now some might say just use the last backup. Well to even acces ir i need a vm on that ssd because nobody plans that ssd especially one from a reputable brand like samsung dies after 4 months of use. Even if mine was rather extreme compared to the usual use of one of them. it's ridiculousthat only 50 bad sectors and a passed smart test causes all the data to be inaccessible. Also the expectationthat I have backups that can survivea nuke is unrealistic. If i had the money i wouldn't use decade old hardware. Now you might say just play video games on your gaming pc. Well i don't have one, all my desktops are on my server and the only other computer that could game properly is copying the drive. I pirated gamesI alreadyown on a laptop for just to play some shitty DM for a dozen mins. This thread is probablybecoming longer then any serious post I made on the fediverse. Anyways now that i dont have a ssd for vms ig i gotta use a dozen decade old hard drives from the discard pile of a graphics design studio since im broke and you cant run multiple windows on a single harddrive cause that shit fucking lagggs. Im so done with this shit, i can even torture myself by editing long overdue videos and ive watched so many video essays that I can't watch anymore. I might just start looking on ebay for like epyc Rome shit or something. HAHA I GOT IT TO COPY AT 135MB/s. So now it's done at 0000... great. STILL BETTER THEN 10 DAYS HAHHAHAHAHAHAHHS OR THE PREVIOUS DAY AND THEN SOME ONTOP JAHAHHAHAHSHSHDHDHHDJDJFHDJDJDJDHHFJDJDJDHDJJFHDHDHFHNFJFNJDJFKFJFJDJDHFH it wasn't done, ddrescuetime calc sucks ass like it's not gonna be like 12 hours instead of 8... all the copying was fine no errors ddrescue didn't see any faulty sectors and yet all my data is shot. I can't boot truenas nor can I extract the config of it.

Friday is update time for my homelab and public servers. Because, should something fail, I have the weekend to fix it. But, as always, nothing failed. All 9 RHEL (Red Hat Enterprise Linux) servers got their `dnf update`, followed by a `reboot`. This time the security updates included important nginx fixes, moderate coreutils stuff. Also a emu-kvm bugfix. All is good, machines and services are up and running again. 20 minutes of well invested time. Coffee next :)

I upgraded Grafana from v12 to v13 and the new unified storage migration for dashboards/folders was a pain in the ass to debug.

If you run Grafana with a hardened securityContext like `readOnlyRootFilesystem: true`, it can fail because backend plugins need writable temp space.

Fix: mount an emptyDir on /tmp.

But I'm not a big fan of that.

RE: https://hachyderm.io/@badnetmask/116736789572154760

After yesterday's power outage I had something banging in my head about the survivability of my cluster.

So today I just decided to tear it down completely, format all the disks, rebuild, and recover from the backup.

And just how I predicted there were a lot of dark corners and hidden skeletons. The rebuild was not clean, there was a lot of ordering/dependency problems, but I was able to go through everything and create a comprehensive step-by-step "how to rebuild from scratch" document.

More lessons learned. All because some construction work is being done nearby and took down the power. 😄

Yesterday I had an unplanned power outage, again, but this time the power company notified me that it would be longer than my UPS(es) would hold, so I had to shutdown everything.

Bringing back my entire network and house automation was a pain, simply because I made a mistake and started stuff in the wrong order. But then I took the opportunity to shutdown everything again and document the proper sequence.

When I'm going to use that again? No idea. This is the first time I've had such a long power outage in 5 years, most of this equipment didn't even exist 3 years ago, and most likely everything will change again in a year or so.

But hey, I feel like I have accomplished something. 😄

I was having some issues with picky destination servers who were rejecting emails sent via a relay. No matter how clean the records/setup were, emails got rejected.

So, I decided to configure exim4 to use satellite mode to send behind NAT without issue. Here's what I came up with using stock exim4 documentation and resources:

Been a while since I blogged, so it's time for the latest installment in "Edd massively over-complicates things with SSH certificates" This time, a post about how I got rid of the need to create a new sub account on my #Hetzner Storage Box every time I wanted to create a new VM and back it up with #Borg. Definitely easier ways to have achieved it, but it shows of the versatility of ssh certificates, and #StepCA that's powering them in my home lab.

Debian 13 installed. SSH is working. The base configuration has been deployed with Ansible. The host is now in my basement under a table, ready to be forgotten. Next step for when I have time will be to configure encrypted ZFS and Jellyfin.

Replaced the motherboard including new CPU and RAM, the host boots correctly now and the keyboard works! It's time to install Debian 13.

Is there anyone out there running an AMD 5650GE based system running Linux or BSD?

Can you tell us your CPU and GPU idle power numbers as displayed in btop?

Maybe this is an "easy button" of sorts to reduce power on an existing AMD AM4 system without going through the machinations of new mobo, ram, etc., etc. Get most of the way there?

I figured out (with some help) how to use an SQL database to monitor #apache with #Grafana, skippimg Prometheus or Loki, which (I think) would explode trying to handle IPv4s, URLs, refrers or User Agents:

So I'm thinking of upgrading my T630 to #proxmox 9 from 8. But since I don't have much there anyways, this could be a chance to switch to something more interesting, penses-tu pas??

Could go the #BSD way and use #bhyve stuff? Orrr try something really interesting, #SmartOS which gives you bhyve AND #KVM AND #zones ??? Oh I do love a good set of choices that just paralyzes me sometimes :D

Anyone use any of these? Are there terraform / pulumi compatible modules for this stuff?

After procrastinating a decision about which Kanban tool to use, I finally weighed all the available choices and landed on @vikunja

I think this was the first time that a software having their presence on Mastodon made part of my reasons to choose something. Another one is the integration with Home Assistant.

So far, so good. Haven't used it for more than a few minutes to create some fake tasks, but it's been nice. Now I need to figure out how to migrate from my old Kanboard.

- accès protégé par SSO Pangolin
- secrets injectés via Gitea Actions
- ports 8080 et 6060 gardés en interne
- captures et retour d’expérience

@gitea are you still interested in people using Gitea, or should we switch over to something else? No responses on the forum or mastodon anymore on user feedback. Helm chart broken for current releases without any response even after multiple pings. What's going on? Silent fade-out of community support and focus on enterprise business?

The Wii homeserver is now live!

My 4th NAS still has a keyboard issue in the BIOS. I tried to replace the CMOS battery, and removed the install USB stick. The PS2 to USB adapter doesn't solve the issue either. I'm trying an unattended Debian install with preseed but the partitioning fails. At least the keyboard works at that moment. I'm close to the solution 🙏

#homelab #selfhosting

Since the last reboot, my dad said that his computer takes a lot of time to boot. The IP address of the NAS has changed, so the NFS mount timed out after 2 minutes. This morning, I remotely re-applied the static IP address as expected and rebooted. But the host didn't come back up. Well, I won't have physical access to the server for months so that sucks. Then I remembered that I have removed my computer from the VPN so the usual ping doesn't work anymore and that's expected. When I tried to connect using the bastion host, it worked.

Rather than just tell @FritzAdalis the answer, let's see how the "wisdom of the crowds" does. Boost for fun. How many nerds does it take to get it right.

These drives are 4TB Seagate ST4000NM0275 SAS drives. Unknown provenance (random eBay seller). Sold at $250 for a lot of 10.

How many power-on hours do they have according to smartctl --attributes /dev/sde?

#selfhosted #selfhosting #homelab #nas

I needed 2 SAS 4TB drives for my NAS. Found a lot of 10 on eBay for $250. Even if only half work, it’s a good deal.

(edit: this isn't how they were shipped. This is how I put them in a box after I unpacked them after shipping)

Now to find a use for the other 8…

You know, sometimes too much visibility is as bad as too little.

I deployed NetAlertX on my network, now I'm seeing a few devices disconnecting the reconnecting to the network at random times. The devices and the times are random, but there are a few patterns I can see by the notifications.

The problem is: this was never a problem before, nothing is really failing, but now it is a problem that is bothering me, and I will probably spend hours trying to find out that it's most likely a whole nothingburger.

Now I'm not sure if it was something worth installing.

Seventeen years ago! I bought this multi-million dollar hoard of Sun servers from a scrap yard for $300. After testing, fixing, and swapping parts to max out some of them, I traded a couple for an SGI Onyx for the museum, a few more for parts of what eventually became my personal 16-proc Origin-2000, and kept two as compute servers for my film making.

(A maxxed-out E4000 has 14 x 400 Mhz UltraSparc II's, and 14 gig of ram (In 128meg sticks! Ha ha ha. Warm.)).

New blog post!

This time it's about procrastination, networking, and most of all about configuring MikroTik devices to work as NATless Access Points.

This blog post was long in the making, but eventually I sat down and wrote it in one go based on the notes I was making along the way. And I hope it will be useful for homelabbers and other people interested in network devices.

I have a #Brother DCP-L2530DW laser #printer that does not connect to my 5GHz network. Is it possible that it only supports 2.4GHz? The manual does not mention technologies, so I'm guessing it doesn't because at the build time there were no alternatives...

Boosts welcome, I'm not sure the hashtags will be enough.

Migration to step-ca certificates renewed by acme.sh client for OpenVPN done successfully. As I have remote only hosts without physical nor public access, the migration was risky.

I have spawned a cloud instance, configured an OpenVPN server with the same configuration as the one I already have. Then, I migrated client by client. Then I have reconfigured the original server. Then, I have updated the remote server on all clients to rebuild the original private network. Finally, I have deleted the cloud instance.

New blog post! I 3D printed a 10-inch (10") rack for my homelab. It was a very long project, but very rewarding at the end. Since I had a lot of help from various people on Mastodon and other communities, I felt like it would be important to show what I did. Also I hope that while I'm sharing my thoughts and the process to get there, I would be able to help other people with their own projects. And if my project works as inspiration for yours, I would be very happy if you let me know about it!

My thanks to my wife, who was with me through the entire process. And thanks to @ironicbadger, @jwildeboer, @rachel and @Fishd for their inspiration.

Lenovo M90q Homelab Upgrade Gone Wrong

I have moved the server to another more accessible room with a keyboard and a screen for the reinstall. The motherboard is so old or minimalist that only VGA is available. Fortunately, it can boot on USB. But there is something weird. The USB keyboard works for like 10 seconds. I have the time to select the boot options but the keyboard becomes unresponsive very quickly. If I boot on the USB, the menu is too long to display so the keyboard is disabled when it's ready. One time, the graphical install automatically started but it failed to display the graphical environment so it required to press any key and it worked! So the keyboard works in a "graphical" environment. The computer just disables it at some point. I have a PS2 port available. But who threw the last PS2 keyboard a few weeks ago? You bet.

It's more complicated than I thought. The computer is hidden under a table in the basement where big spiders have their web. On the technical side, the case cannot fit 2 more drives, neither the power supply. My best option is to replace the existing 2*1TB disks with 2*4TB.

I had an awesome time leading an informal conversation about using home labs as a learning tool during DevOpsDays Raleigh. It was fun to talk to people in various stages of the spectrum: some who want to start one all the way to people who gave up on it. 😄

#DevOpsDays #DevOpsDaysRaleigh #HomeLab @homelab

Swapped a bunch of HDDs yesterday in my #homelab. I now have 2*4TB to add to one of my NAS that could become a media server. I plan to replace TrueNAS by Debian with ZFS and install Jellyfin on top of that.

Pangolin 1.18 est sorti.

Grosse évolution côté plateforme :

I have created some very basic alert rules for Blackbox Exporter, just to have something to start and get a feeling about what I may or may not need. Feel free to copy.

By the way: I dropped any actual "ping" tests, and I'm doing some cross-checks with healthchecks.io

Well. Thanks to @rachel and @viq , I have now migrated from Uptime Kuma to Prometheus Blackbox Exporter.

As much as I loved to have Uptime Kuma, I need something more declarative, and Blackbox works really well.

Hey @homelab and @homeassistant, I have an integration that needs a periodic renewal of a token, and when the token is expired, some important things don't work. Is there a way to have an automation triggered by the notification that this token is expired so that I can make it notify me?

My new server has arrived! It’s a Lenovo ThinkCentre M90q with a 10th-gen Intel Core i5. It’s got two m.2 2280 slots, 2 RAM slots, a SATA port, and a m.2 Wi-Fi card.

Oh yeah…it also has a PCIe 8x slot that I’ll be stuffing a GPU into for local LLM use.

Need to buy more RAM, but Proxmox is going straight onto this thing tonight!

It’s a Lenovo ThinkCentre M90q! Been wanting one of these for awhile.

Here is the backside with all of the ports, including 10GB USB 3.2 Gen 2. Sadly, no 2.5Gb Ethernet. Gonna’ have to use a dongle.

Here it is with the top cover removed. On the left is the 2.5” SATA drive cage. The right is the heatsink and fan assembly. The m.2 slots and RAM are located underneath the unit under a cover.

Here’s a shot of the 8x PCIe slot. With a riser, I can stick a low-profile GPU in here, believe it or not.

Today's tech screw up:

I botched an upgrade on Zentyal, our Active Directory alternative. So, being a good sysadmin, I triggered a restore from our Veeam platform, which dutifully shut down the broken VM and began the restore operations.

Using a service account that's stored in active directory. The restore failed, and now I'm reconfiguring my backup software to use locally stored service credentials.

You live and learn!

#sysadmin #homelab

Does anyone have any suggestions for running an Active Directory replacement inside Linux?

I've been using Zentyal for a few years, and I'm just a little sick of using it now.

#homelab #sysadmin

@aral Yep. It’ll be interesting to see if it’s as easy as I hear it is. I’ll be migrating…9 containers, I suppose, since I shouldn’t need wud or dockhand anymore. Maybe 8 if I don’t need cockpit? I guess I’ll find out!

I’l post updates as it goes along.

Update on the lab rack decision: I started printing the Lab Rax. It has the minimum size that I need (5U) and can be expanded (up to 10U). It also has a very strong community behind it, which will make it very easy to find parts.

I'll be sure to post photos when I'm done.
