Setting Up Volume Topology in the MapR Control System

MapR supports data placement control, in which you can place a volume on specific racks, nodes, or groups of nodes by setting its topology to an existing node topology. You can set volume topology using the MapR Control System or with the volume move command.
  1. In the Navigation pane, expand the MapR-FS group and click the Volumes view.
  2. Display the Volume Properties dialog by clicking the volume name or by selecting the checkbox beside the volume name, then clicking the Properties button.
  3. Click Move Volume to display the Move Volume dialog.
  4. Select a topology path that corresponds to the rack or nodes where you would like the volume to reside.
  5. Click Move Volume to return to the Volume Properties dialog.
  6. Click Modify Volume to save changes to the volume.
