What happened?


I’ve been taking a break. I’ve found that with the restrictions on activities due to (or rather, rationalized by) COVID19, I’m having work-life balance issues all over the place.

I”m still working on the cluster, and I have some posts in the pipeline, but it’s going to be a while before I’m able to put the kind of time in required to maintain the pace I’ve had since March. That is, if I ever get back to there, which is questionable because it’s manifestly unhealthy.

I hope everyone reading this is safe and healthy. These are trying times. Take breaks if you need them.

Reboot


Last night, I tore down the entire stack and rebuilt it. This was to accommodate two things:

  • The release of Ubuntu 20.04, which required an upgrade, and
  • A hardware change involving using USB flash drives for the root file system on all nodes, rather than just a micro SD card.

As a result of this, I’ve come up with some changes to node provisioning – the steps required to go from bare hardware to an operating node. I’m planning a step-by-step guide for building out the cluster based on this. Stay tuned.
