class_docstr: Error indicated CLUSTERDOWN error received from cluster.
  By default Redis Cluster nodes stop accepting queries if they detect there
  is at least a hash slot uncovered (no available node is serving it).
  This way if the cluster is partially down (for example a range of hash
  slots are no longer covered) the entire cluster eventually becomes
  unavailable. It automatically returns available as soon as all the slots
  are covered again.
