Obtain estimation information of the storage pool capacity. You can obtain the estimation information by specifying the number of storage nodes or drives to be added to the current configuration or the number of drive failures that can be tolerated to which you plan to change.

  • estimatedPoolCapacityInTiB: Capacity estimation result [TiB]. If logical capacity cannot be configured, null is output.

  • differenceCapacityInTiB: Difference between the current logical capacity and estimatedPoolCapacityInTiB [TiB]. If logical capacity cannot be configured, null is output.

  • numberOfStorageNodes: Number of storage nodes to be added that was specified. If not specified, null is output.

  • numberOfDrives: Number of drives to be added for each storage node that was specified. If not specified, null is output.

  • numberOfTolerableDriveFailures: Number of drive failures that can be tolerated in the specified configuration. If not specified, null is output.

  • Required role: Storage or Monitor

  1. Verify the storage pool ID whose capacity is to be increased.

    REST API: GET /v1/objects/pools

    CLI: pool_list

  2. Run the following command.

    Run the command by specifying the storage pool ID and the parameters for capacity estimation (numberOfStorageNodes, numberOfDrives, or numberOfTolerableDriveFailures).

    REST API: GET /v1/objects/pools/<id>/estimated-capacity-for-updated-configuration

    CLI: estimated_capacity_for_updated_configuration_show

    Note:

    If you run the commands in an environment in which the Floating base license is not applied, the job will be unsuccessful.
