nixos-docker-sd-image-builder: Error while copying store paths to image

Hi!

This project seems very promising and your blog post is very nice, so thank you!

While trying to make it work as-is (I just updated the SSH key), everything seems to work fine until I get the following error:

I’m using the latest Docker Toolbox on Windows 10:

Docker version 19.03.1, build 74b1e89e8a
docker-compose version 1.24.1, build 4667896b

I tried to put 2 GB of RAM (instead of 1) in the VM (Docker Toolbox runs Docker inside a VirtualBox VM), but nothing changed.

Any idea of what could be wrong or how to investigate?

Replace `resize2fs` patch with nixpkgs#82718 The patch fixes both issues with `cptofs` (see #1) and the original issue fixed by my patch. It makes sense to prioritize applying that rather than mine. — committed to Robertof/nixos-docker-sd-image-builder by Robertof 4 years ago

Just to say I encountered this today, and just bumping my Docker memory from 2 to 12GB worked nicely. Many thanks to @Robertof and @SuperCipher!

Hey @ccamrobertson – as promised, I’ve played around with the various configurations and made this repo (hopefully) RPi 4 compatible! 🎉

However, I was not able to reproduce your issue – i.e., even using the config you gave me verbatim the build succeeded at the first try. Could there be something weird on the host OS, e.g. strange limits/extremely out-of-date Docker/not enough disk space? Note that it should also work on macOS as in theory Docker just virtualizes a Linux distro to work on macOS.

Feel free to pull this repo, change rpi3 to rpi4 in config/sd-image.nix and give it another shot. Note that I’ve added first-party support to the patch which removes cptofs, so you should only need to change the flag in docker/docker-compose.yml.

Thanks! Roberto

Thanks! I don’t see any issue with your configs. I’ll experiment with it this evening and let you know!
