Anonymized & Summarized Issue

Summary: A user reports an outdated AFS directory (/afs/desy.de/group/atlas/naf-1/) that appears to be no longer actively used. The directory contains multiple subdirectories (e.g., users/, software/, DUW09/, etc.), some of which may belong to former users or deprecated projects. The user inquires whether the directory and its contents can be safely removed.

Solution/Next Steps: 1. Verify Usage: - Check access logs or last timestamps for the directory and its subdirectories to confirm inactivity. - Contact potential stakeholders (e.g., experiment group admins via naf-atlas-support@desy.de) to confirm whether the data is still needed.

  1. Backup (if needed):

  2. If the directory contains critical data, create a backup (e.g., tar archive) before deletion.

  3. Cleanup:

  4. If confirmed unused, remove the directory with: bash rm -rf /afs/desy.de/group/atlas/naf-1/

  5. Note: AFS permissions may require admin assistance for deletion.

  6. AFS-Specific Considerations:

  7. AFS directories with many files/subdirectories may impact performance (see AFS context).
  8. Symlinks in AFS paths can cause issues with tools like Apptainer (workaround: -B /afs --no-home).
