Good on you for starting a node.

However, expect heartbreak with the Pi. It isn't really up to the task. Rickety connection to your block storage is never not precarious.

Don't do LN with that thing.

Learn what you can and then consider a more robust serup. I have been using an upgaraded (storage and RAM) older Thinkpad.

The "you can run a node on a Pi!" Narrative was actually a kind of disservice to have been so widely parroted.

But incremental steps are superior to no steps.
