HPE Ezmeral Data Fabric 6.2 Documentation

6.2 Administration
This section describes how to manage the nodes and services that make up a cluster.
- Administering Users and Clusters
  Lists topics that help manage a data-fabric cluster.
- Administering Nodes
  Provides a synopsis of managing nodes in a cluster.
- Administering Volumes
  This section provide information about how to organize and manage data using volumes, a unique feature of HPE Ezmeral Data Fabric clusters.
  - Managing Data with Volumes
    Provides an overview of how to manage volume data.
  - Managing Snapshots
    This section provide information about managing snapshots.
  - Managing User Disk Usage
  - Managing Schedules
  - Managing Tiers
    - Enabling Tiering
      Describes how to enable data tiering using both the Control System and the CLI.
    - Creating a Storage Tier
      Describes how to create a sotrage tier using the Control System and the CLI.
    - Viewing the List of Tiers
      Describes how to view the list of tiers using the Control System, the CLI, and the REST API.
    - Editing a Tier
      Describes how to modify a cold tier using the Control System, the CLI and the REST API.
    - Specifying a Tier
      Describes how to associate a tier with a tiering-enabled volume using the Control System and the CLI.
    - Removing a Tier
      Describes how to remove a tier that is not associated with a tier, using the Control System, the CLI and the REST API.
  - Managing Storage Policies
  - Using Storage Labels
    Describes the Storage Labels feature.
- Administering Files and Directories
- Administering Tables
  Administration of the HPE Ezmeral Data Fabric Database is done primarily via the command line (maprcli) or with the MapR Control System (MCS). Regardless of whether the HPE Ezmeral Data Fabric Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. HPE Ezmeral Data Fabric Database administration is associated with tables, columns and column families, and table regions.
- Administering Streams
- Administering Data Fabric Gateways
  A HPE Ezmeral Data Fabric gateway mediates one-way communication between a source HPE Ezmeral Data Fabric cluster and a destination cluster. You can replicate HPE Ezmeral Data Fabric Database tables (binary and JSON) and HPE Ezmeral Data Fabric Event Data Streams streams. HPE Ezmeral Data Fabric gateways also apply updates from JSON tables to their secondary indexes and propagate Change Data Capture (CDC) logs.
- Administering Services
- Monitoring the Cluster
  This section describes how to monitor the health and performance of a MapR cluster.
- Configuring Security
  Describes how to configure MapR security and manage secure clusters.
- Managing Secure Clusters
  Provides procedures that will enable you to use MapR clusters securely.
- Administering the Data Access Gateway
  The HPE Ezmeral Data Fabric Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight client applications and the HPE Ezmeral Data Fabric cluster. This section describes considerations when upgrading the service, how to modify configuration settings, and how to administer and manage the service.
- Planning for High Availability
- Administrator's Reference
  This section contains in-depth reference information for the administrator.
- Troubleshooting Cluster Administration
  Lists the common errors and their solutions.
- Best Practices for Backing Up HPE Ezmeral Data Fabric Information
  Lists the best practices and performance considerations to follow when backing up HPE Ezmeral Data Fabric information.
