Arvados

Check to see what it does now -- difference between reload/restart, check what the systemd unit files do.

I have been doing manual tests, both on single and multi host installations, and both arvados-controller and arvados-dispatch-cloud get restarted correctly after a config change.

The config change that I did was just setting up a custom message in Workbench.WelcomePageHTML at the local_config_dir/pillars/arvados.sls file.

Without being able to reproduce the issue, it's difficult to know what was the problem.

In the arvados salt formula, every service has a running.sls file that describes each running services, for example arvados/dispatcher/service/running.sls:

arvados-dispatcher-service-running-service-running:
  service.running:
    - name: {{ arvados.dispatcher.service.name }}
    - enable: true
    - watch:
      - sls: {{ sls_config_file }}
    - require:
      - pkg: arvados-dispatcher-package-install-pkg-installed

The service.running.watch.sls parameter makes the service restart when the config file changes. Service reload doesn't happen unless a service.running.reload: true is set, and it isn't the case in our formula.
