Moving All Other Volumes to a Topology Separate from the CLDB-Only Nodes

  1. Move all non-CLDB nodes to a non-CLDB topology (e. g. /defaultRack) using the MapR Control System or the following command: maprcli node move -serverids <all non-CLDB nodes> -topology /defaultRack
  2. Restrict all existing volumes to the topology /defaultRack using the MapR Control System or the following command: maprcli volume move -name <volume> -topology /defaultRack All volumes except mapr.cluster.root are re-replicated to the changed topology automatically.
    Warning: To prevent subsequently created volumes from encroaching on the CLDB-only nodes, set a default topology that excludes the CLDB-only topology.
