Name

nix-store --verify - check Nix database for consistency

Synopsis

nix-store --verify [--check-contents] [--repair]

Description

The operation --verify verifies the internal consistency of the Nix database, and the consistency between the Nix database and the Nix store. Any inconsistencies encountered are automatically repaired. Inconsistencies are generally the result of the Nix store or database being modified by non-Nix tools, or of bugs in Nix itself.

This operation has the following options:

  • --check-contents

    Checks that the contents of every valid store path has not been altered by computing a SHA-256 hash of the contents and comparing it with the hash stored in the Nix database at build time. Paths that have been modified are printed out. For large stores, --check-contents is obviously quite slow.

  • --repair

    If any valid path is missing from the store, or (if --check-contents is given) the contents of a valid path has been modified, then try to repair the path by redownloading it. See nix-store --repair-path for details.
