It runs quite nicely on my Pi 3 with Apache and no Docker. I only use cloud storage, but the rest seems to work fine if needed. Maybe switching to a supported configuration would help?

Valid points. I was thinking of using a second drive. That way you’d still have this one to troubleshoot and learn from.

Could it be a failing/failed drive? Maybe try making a new bootable flash drive and see what happens.

I’ve participated in their SETI and cancer research projects in the past. It’s a good cause, and I don’t mind making a donation.

I did think the BOINC project was shut down, though. Good to know it’s still going.

Understandable, but if you’re sharing it, it’s not private in that sense anyway. This may be a legitimate use case for GDrive, Dropbox, Box, etc. Or just use sneakernet.

Have you looked at NextCloud? I have an instance running on an RPi that fits my needs (storage without sharing outside the home firewall). For anything that needs sharing, I just copy those images to an old Dropbox that I’ve kept and share from there.

Why link to Reddit? Just give credit to the original source and be done.
