Yeah, my Proxmox cluster hasn’t even been fully operational for 48 hours yet, and I’m already writing an article titled “Mistakes Were Made.” I genuinely wish I had known some of this beforehand, because it would have saved me time and, quite possibly, money. Storage I am already running out of storage. Yes. Not even…

Proxmox HA is alive!
This weekend was D-Day for my Proxmox HA/Ceph cluster. Spoiler alert! It actually runs! And yes, this took way longer than expected, and I had a serious run-in with Mr. Murphy. More on that later. Photos All three nodes, side by side. And yes, I bought another NOX 010 case. It differs from the NOX…
Proxmox HA host update
It has been a while since I posted an update about my Proxmox homelab. Memory I upgraded the “Logos” from 64 GB to 96 GB after finding a reasonably priced 2×32 GB memory kit. After installation, I ran extensive MemTest86 checks; everything passed without issues. Unfortunately, memory prices are going through the roof at the…
Proxmox software update
And a sooner-than-expected software update, or rather; a VM update. Today I migrated the three remaining VMs from my office node to my main Proxmox host at home. All three VMs belong together: a PostgreSQL database, a Python development machine, and an Nginx reverse proxy. As I had never migrated VMs before, it sounded like…
And another Proxmox update!
It is now almost a year ago that I started my Proxmox journey. Almost exactly a year ago Microsoft decided to push the infamous Windows 11 update and subsequently wrecking my homeserver in the process. And right now, I have a few more interesting things to talk about. Hardware “Node 3” is almost finished. I…
Proxmox update: 10Gbe network. CHECK
Nerd alert! The three Intel X710 10Gbe network cards are in! Thank you Ebay! ( in earnest this time! 🙂 Port 1 will be used for the Ceph sync for the VM’s. Port 2 will be used for data towards my network. More soon! Brain out!
BEEP, BEEP, BEEP, NO POST
Yeah, I know. That’s one hell of a cryptic title for this POST (pun intended 😛 ). Proxmox node 3 Yes! This post is about the third Proxmox node I’ve been assembling. Last Sunday, I finally had some spare time to install everything into the newly bought case. The process itself was straightforward: add extra…
Proxmox update
And time for a short Proxmox HA update. Hardware The first new — or actually, second-hand — hardware is coming in. I found a used 10 Gbit Ubiquiti XG 16 GEN 1 switch for a nice price. It comes with ten SFP+ ports and four regular RJ-45 ports, all supporting up to 10 Gbit. Core…
From Single point of failure to High Availability
I wrote before about backups. https://www.familie-kleinman.nl/brain/index.php/2025/04/12/backup-stories-what-was-needed-to-get-to-never-again/ . Backups are the last line of defense. If everything else fails, you fall back on them. But that raises the question: what’s the first line of defense, and what can you build in between? Having your data on multiple hard drives, in RAID, is such a defense. One…
Hammer was shutdown suddenly
This morning I got downstairs, opened my laptop and checked out my Bluesky account. First symptom.. Bluesky loaded slowly, seemed DNS resolving was slow as well. Tried to access my DNS / PiHole instance. Unreachable…. I decided to check my new Uptime Kuma console to verify network issues. Huh, site unreachable too?! Tried to ping…
