restart()

(Action) Restart the admind instance. Only works for slave instances and is intended to 

 be triggered by <tt>/meta/restart</tt>.

70:       end
shutdown()

(Action) Shut down the admind instance. Only works for slave instances and is intended to 

 be triggered by <tt>/meta/shutdown</tt>.

    # File lib/dsadmin/admind/local_controller.rb, line 75

83:         }
84:       end
sync_instance()

(Action) Ensure the current instance‘s files (code and configuration) are identical to the ones in a central repository (typically the master instance). This essentially executes the command in configfile:/modules/meta/sync_command. Intended to be triggered by /meta/sync_instances.
