After greybeard_graham's tweet ("a backup you have never restored is a rumour") I feel personally attacked, so last weekend I finally do a real restore test. Not "I see the files in B2", a real restore to a new VM, start the apps, use them. Result: 3 OK, 2 broken. Nothing was lost because the originals are fine, but if the NAS died last month, I would lose all my scanned documents. Here is the story. The setup…
Reminder from an old man who has seen things: a backup you have never restored is not a backup. It is a rumour. Cheers, G.
Rainy season in HCMC. Some weeks we have 2-3 power cuts, 10 to 40 minutes. My APC Back-UPS 1000VA can run my 186W lab for ~18 minutes (UPS says), so for long cuts everything must shut down cleanly by itself, even when I am at work or asleep. This is how I do it with NUT (Network UPS Tools). Plan The UPS USB cable goes to one machine. That machine is the NUT primary (server) All other machines are secondary (clients)…
Problem: when my parents watch something on the phone, Jellyfin transcode on CPU and the i5-8500T go to 95%, fans loud, and everything else on that node become slow. The iGPU (UHD 630) was sitting there doing nothing. It took me 2 evenings to make Quick Sync work inside an unprivileged LXC, so here is everything. 1. Check the host ls -l /dev/dri crw-rw---- 1 root video 226, 0 ... card0 crw-rw---- 1 root render 226,…
someone in a Facebook group just share a screenshot of his Portainer, on public IP, no login, asking "how to secure?" bro. it is already too late. wipe it, put it behind Tailscale or WireGuard, then we talk. please :(
Every few weeks someone on here tells me the cloud is cheaper. Sometimes it is. So I sat down with a pot of tea, my power bill, and my receipts, and worked it out properly. I have included the numbers that do not flatter me, because a comparison that only counts one side is an advertisement. What is in the spare room One Dell OptiPlex 7060 Micro, i5-8500T, 32GB, running Proxmox. About a dozen containers and two…
G'day legends. This took three weekends, two trips to Jaycar and one very long conversation with the wife about "what exactly is a control plane". Years ago Jeff Geerling's Pi Dramble videos put the idea in my head and it never left, so if you've not seen the original, start here: This is the full log. Every command I ran, everything that went wrong, and at the end an honest answer to "should you build one". Parts…
Last month one of my 8TB drives die at 2am on a Tuesday. Nothing was lost, because ZFS mirror, but I learn a few things that I want to write down before I forget. The pool TrueNAS SCALE, one pool called tank , 4 × 8TB in two mirror vdevs . Each mirror is one WD Red Plus + one Seagate IronWolf, bought from different shops in different months, so they are not from the same batch. TrueNAS does this in the UI, but this…
سلام. I write backend for a ride hailing and delivery app in Tehran, Go and Python, team of 14. Many people outside do not know what sanctions mean for a normal developer, and many developers in other sanctioned countries ask me the same questions. So this is the long version. Everything here is about using public open source and running things ourselves. Nothing exotic. The real problem is over-compliance US…
Last June, for twelve days, there was a war over my head. I do not want to explain Iran in one post, I cannot, and people who ask me to do it in one comment are usually not asking a real question. I only want to write what happened to my work, because many developers in many countries may need this one day, and I hope they never do. The first nights we heard explosions in Tehran. My parents went to my aunt in the…
Howzit. A few people asked after my comment in the homelab thread, so here's the long version. Ja, it's long. Make tea. Context for the non-South Africans: for a few years "load shedding" was just life here. Scheduled power cuts, two to four hours at a time, sometimes three times a day, announced by stage (stage 2, stage 4, stage 6 when things were really bad). You planned your cooking, your gym, your deploys and…
Many people ask in my Self Hosted topic "what do you actually run", so here is the full tour. It start 4 years ago as one old laptop under the TV. Now it is a 12U wall cabinet in the corner of our spare room, and my wife call it "the heater". Hardware pve1, pve2: Lenovo M720q Tiny, i5-8500T, 32GB RAM, 1TB NVMe each. Bought second hand, very good value pve3: HP EliteDesk 800 G4 Mini, i5-8500T, 32GB, 512GB NVMe NAS:…
Hi all, this is my first long post here. My Pi 3B is the oldest thing in my homelab and still the most important, because when it is down the whole house have no internet and my wife know exactly who to blame :) Why Unbound and not only Pi-hole Pi-hole alone block ads, but it still forward every query to some upstream (Google, Cloudflare, or your ISP). My ISP DNS here sometimes is slow, and when I type a domain…
