Setting Up Volume Topology to Restrict the CLDB Volume to Specific Nodes

Explains how to permit access to CLDB volumes only from specific nodes.

Procedure

  1. Move all CLDB nodes to a CLDB-only topology (e. g. /cldbonly) using the data-fabric Control System or the following command:
    maprcli node move -serverids <CLDB nodes> -topology /cldbonly
  2. Restrict the CLDB volume to the CLDB-only topology using the data-fabric Control System or the following command:
    maprcli volume move -name mapr.cldb.internal -topology /cldbonly
