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

Explains how to move non-CLDB volumes to a separate topology.

Procedure

  1. Move all non-CLDB nodes to a non-CLDB topology (e. g. /defaultRack) using the data-fabric 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 data-fabric 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.
