Good Morning from my Robotics Lab! This is Shadow_8472 with a small update on what I learned this week. Let’s get started!
Not much progress happened this week. I won’t be clustering this month, but I did study the High Availability Add-On. It has a package name in there called Pacemaker, but I don’t know if it’s independent or a common library or what. Furthermore: I don’t know if a high availability cluster is right for me or not. I circled back around to Beowulf clusters after over a year of stuggle, but couldn’t conclusively tell if Red Hat’s implementation is one or not. Best I can figure is that you Beowulf once you have your task working on the first node and need to expand.
With that said, I did have some trouble along the way. Joystick, my new Rocky Linux 9 installation won’t boot – the computer keeps going to Mint no matter what I say in the BIOS. I tried running update-grub on Mint, but that just tidied away Debian with no new Rocky option. I vaguely remember something like this happening before, but I could be misapplying a memory. I want to try a GRUB disk; if that doesn’t solve it, I may need to reinstall. I still have the USB stick.
On a tangentially related note, I checked in on ButtonMash when Joystick didn’t boot and found it unupdated. It also thought it was July, 2018 and that everyone’s SSL encryption certificates were bad until I’d completely fixed the time. I suspect the motherboard’s system clock battery may be experiencing issues.
In conclusion for this month, I’ve been burned out. It’s been nice not having the near-constant stress of finishing a project or taking a walk of shame to split it off into [yet] another week, but at the same time, I didn’t get much done at all.
I still have a goal of combining multiple computers into a single, more powerful one behind a unified Cockpit experience. If I think about it though, I might be after some sort of Podman clustering technique, and I’ll still be no better off at getting Podman working over NFS than when I started!
