Permission denied "/data/database/postgres" on import with nfs mount volume

Permission denied (/data/database/postgres) when using external PV (persistant volume) mount.
It works with Docker osm-data volume. Luxemburg is ok, but Europe is too big. Fills whole VM, then fails.

Docker Compose:

    volumes:
      # original Docker volume NOT USED because it will fill complete VM!
      # - osm-data:/data/database
      # PV mount
      - /mnt/nfs_pv_swarm/osm/data/database:/data/database
      - /mnt/nfs_pv_swarm/osm/data/tiles:/data/tiles
      - /mnt/nfs_pv_swarm/osm/data/style:/data/style
      # OSM Region Europe
      - /mnt/nfs_pv_swarm/osm/europe-latest.osm.pbf:/data/region.osm.pbf
