MapR 5.2 Documentation

5.2 Cluster Administration
This section contains information on administering the cluster and MapR-DB, configuring Gateways, and configuring and managing particular aspects of the MapR security infrastructure.
- Administering the Cluster
  This section describes how to manage the nodes and services that make up a cluster.
- Monitoring the Cluster
  This section describes how to monitor the health and performance of a MapR cluster.
- Configuring and Managing MapR Gateways
  A MapR gateway mediates one-way communication between a source MapR cluster and a destination cluster. MapR-DB tables and MapR Streams streams can be replicated.
- Administering MapR-DB
  Administration of the MapR-DB is done primarily via the commmand line (maprcli) or with the MapR Control System (MCS). Regardless of whether the MapR-DB table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. MapR-DB administration is associated with tables, columns and column families, and table regions.
- Configuring Security
  Describes tasks for configuring MapR security, managing secure clusters, and administering auditing.
- Administrator's Reference
  This section contains in-depth reference information for the administrator.
  - maprcli and REST API Syntax
    This section provides information about the MapR command API. Most commands can be run on the command-line interface (CLI), or by making REST requests programmatically or in a browser.

volume move

Moves the specified volume or mirror to a different topology. Permissions required: m or fc on the volume.

Syntax

CLI

maprcli volume move
    [ -cluster <cluster> ]
    -name <volume name>
    -topology <path>

REST

http[s]://<host>:<port>/rest/volume/move?<parameters>

Parameters

Parameter	Description
cluster	The cluster on which to run the command.
name	The volume name.
topology	The new rack path to the volume. NOTE: To move the volume to another topology, you must have the Converged Enterprise Edition installed on your system.
