nix-build, ob deploy runs out of space

[johnny555]

Hi, I'm trying to deploy obelisk and I've run into an out of space error. I've tracked it down to when nix-build happens and I can reproduce it with

nix-build -A exe --no-out-link --show-trace

building '/nix/store/b6xjzaabl82ycajh0142fd7rfm0cl2h6-obelisk-generated-static-0-js-unknown-ghcjs.drv'...

writing to file: No space left on device

The static folder just contains a few files, no sub directories and none of them are sim-links. So I don't know what is wrong.

I encounter this issue as well. You can try revering version back to 11beb6e8cd2419b2429925b76a98f24035e40985 to workaround this issue (even though it works for me, I can't tell if this revision is fine or simply because I have certain binary cache).

You can do this by modifying .obelisk/impl/github.json to

{
  "owner": "obsidiansystems",
  "repo": "obelisk",
  "branch": "master",
  "private": false,
  "rev": "11beb6e8cd2419b2429925b76a98f24035e40985",
  "sha256": "0b4m33b7yyzsbkvfz2kwg4v9hlnvbjlmjikbvwd7pg52vy84and0"
}

Not sure if related:

I just got "no space left on device" when trying to deploy to an aws ec2 instance (building locally via nix-build works fine). I had this before. I ssh'd into the instance and ran nix-collect-garbage -d, which deleted 4.8 GB of data. This alone seems excessive -- no clue why my project would need so much ever. Also, this garbage collection could be an automated part of deployment, or even more: when I deploy, I don't rely on any data that is still stored on the instance - it just should be wiped.
