Recently, I wrote about being wrong. Specifically germane to this post, I wrote: Being wrong means I probably had some gross misunderstanding of a system’s architecture or the operation of a program, and that means I have an opportunity to learn more about it, and hopefully to be able to guide my decisions. I was involved in an incident where I thought that some EC2 instances had reached disk saturation. This was primarily driven by three factors: referencing an outdated man page, tunnel vision, and missing the units on a graph....

I wrote previously about how some things should just work, should not need mucking about with, and how I shifted my NAS’ duties to TrueNAS Scale. I must now inform you that I was incorrect, and have shifted back to running it manually on Debian. I’m a creature of habit. I also like knowing how things work, how to fix them when they don’t, and how to improve them. While TrueNAS (Scale, anyway; I assume Core also) does begrudgingly allow you to ssh in, the MOTD is a warning banner that they guarantee nothing once you’ve touched it outwith their blessed API path....

I grew up playing with computers. Our first computer was a Packard Bell 286, and I fondly remember getting a book on BASIC and trying to make a game with it. Later, we got a Gateway 2000 486, and on at least two occasions, I broke it by editing autoexec.bat and config.sys. A few years later, we got a Gateway (at this time, they had rebranded) Pentium III 550 MHz, which was an absolutely screamer for its time....

In case you haven’t been following my work (I absolutely can’t blame you, as this blog is self-congratulatory at best), I have a 25U rack with some stuff in it. In short, it consists of a Supermicro 2U X9, and a ZFS pool, with an almost-identical second Supermicro 2U X9 that exists as a cold spare, and a ZFS backup target. There’s also a Dell R620 1U that I’ve done absolutely nothing with yet beyond installing Proxmox....
