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

  1. Move all CLDB nodes to a CLDB-only topology (e. g. /cldbonly) using the MapR Control System or the following command: maprcli node move -serverids <CLDB nodes> -topology /cldbonly
  2. Restrict the CLDB volume to the CLDB-only topology. Use the MapR Control System or the following command: maprcli volume move -name mapr.cldb.internal -topology /cldbonly
  3. If the CLDB volume is present on nodes not in /cldbonly, increase the replication factor of mapr.cldb.internal to create enough copies in /cldbonly using the MapR Control System or the following command: maprcli volume modify -name mapr.cldb.internal -replication <replication factor>
  4. Once the volume has sufficient copies, remove the extra replicas by reducing the replication factor to the desired value using the MapR Control System or the command used in the previous step.
