    Description

      Imperative recovery means the clients are notified explicitly when and where a failed target has
      restarted. Ideally the notification should occur after the target has mounted and is waiting for
      connections. A fully automated version of this will require a new mechanism for distributing node
      health information efficiently. A simple, initial version can be done as a /proc file for each
      import that can be used to initiate recovery.
