Steps To Reproduce
The nix-gc.service crashes every time when executed for me. It has already crashed 3 times before I discovered it. But I'm not sure if it's reproducible on other machines.
Expected behavior
No crashing.
Even on crashing, it should keep database consistent, ie. un-registering paths before deletion.
Metadata
> nix-env --version
nix-env (Nix) 2.32.4
Additional context
I found my nix-gc service failing because my nix database is inconsistent with store paths in filesystem.
I'm fairly sure that the database inconsistency comes from nix-collect-garbage because it is the only abnormal thing that works on it. This desktop computer has been (and is still) running for more than 10 days with no crashing, power cut, or any disk problems. The NVME disk is healthy, no warnings or errors from dmesg, and a btrfs scrub shows nothing wrong. The memory should be also fine because I played some memory-intense games on it without any issue.
I'm using nix frequently if not daily for build environment and temporary packages, it only start to show random error: getting attributes of path '/nix/store/br3nr5ymp1p8k9gn9zljmbnsksikj98l-stdenv-linux': No such file or directory errors when I'm updating my nixos config. The exact path in message changes. After some digging, I found that many paths are registered in database but not in filesystem:
> stat /nix/store/br3nr5ymp1p8k9gn9zljmbnsksikj98l-stdenv-linux
stat: cannot statx '/nix/store/br3nr5ymp1p8k9gn9zljmbnsksikj98l-stdenv-linux': No such file or directory
> nix-store --realise /nix/store/br3nr5ymp1p8k9gn9zljmbnsksikj98l-stdenv-linux
warning: you did not specify '--add-root'; the result might be removed by the garbage collector
/nix/store/br3nr5ymp1p8k9gn9zljmbnsksikj98l-stdenv-linux
> stat /nix/store/br3nr5ymp1p8k9gn9zljmbnsksikj98l-stdenv-linux
stat: cannot statx '/nix/store/br3nr5ymp1p8k9gn9zljmbnsksikj98l-stdenv-linux': No such file or directory
I double-checked it by inspecting the database directly, and it matches my guess. I guess it's being deleted by nix-collect-garbage but it crashes soon?
