Nixpkgs: No ipfs repo found after nixos-rebuild

[matthiasbeyer]

Issue description

After updating to the latest unstable channel, the ipfs service does not find the repository in /var/lib/ipfs anymore.

Steps to reproduce

I'm not sure, maybe updating is enough...

Technical details

• System: 17.09pre107265.0afb6d789c (Hummingbird)
• Nix version: nix-env (Nix) 1.11.9
• Nixpkgs version: "17.09pre107265.0afb6d789c"
• Sandboxing enabled: build-use-sandbox = true

You may want to cc the maintainer of the package/service.

[matthiasbeyer]

Yep.

[mguentner]

Please post the logs (journalctl -u ipfs -r) - it might be due to a repo version change of ipfs. That requires a manual migration.

[mguentner]

Please try:

services.ipfs.dataDir = "/var/lib/ipfs/.ipfs/";

[Infinisil]

Since the ipfs service before ignored the dataDir option, it would always get set to ~/.ipfs which is the default, with the home directory for the ipfs user being /var/lib/ipfs by default, this resolves to /var/lib/ipfs/.ipfs.

We should probably note this somewhere that the data needs to be moved to the correct location when updating.

mv /var/lib/ipfs/.ipfs/* /var/lib/ipfs && rmdir /var/lib/ipfs/.ipfs

should do.

Edit: Or as @mguentner said, just set dataDir to the old directory.

[mguentner]

We could simply make /var/lib/ipfs/.ipfs the default value - that reflects the old default behaviour

[Infinisil]

That too would be an option. Could we maybe even use something like `if system.stateVersion <= 17.03 then "/var/lib/ipfs/.ipfs" else "/var/lib/ipfs"? It seems like that option is there for exactly something like this.

After settings dataDir:

[matthiasbeyer]

ipfs is started, though. Thanks so far. Feel free to close this!

[Infinisil]

Yeah that's a known bug that's been there before (see my last comment on #25531), I'm just working on it :)
