Extending Node Storage

If a cluster on Oracle Data Hub Cloud Service is running out of storage, you can extend the existing storage volumes.

Extending a storage volume does not add the new value to the existing value, but sets the storage volume to the defined value. For example, if your current storage volume is 50GB and you define the new value as 100GB, the storage volume is extended to 100GB, not 150GB.

Note:

For nodes of clusters provisioned in Oracle Cloud Infrastructure, the scaling increment for the storage volumes is 50 GB.

To extend node storage:

  1. Open the Oracle Data Hub Cloud Service Console.
  2. Click the name of the cluster with the node you want to add the storage.
    An overview page with cluster details is displayed. Nodes are listed under Resources.
  3. From the Menu icon menu for the node, select Add Storage.
    The Add Storage overlay is displayed.
  4. Add storage to the node as desired:
    • Data Storage in GB: The node’s current data volume storage value appears in this field. Increase this number to the desired data storage value for this node.

    • Storage for commit log volume in GB: The node’s current commit log volume storage value appears in this field. Increase this number to the desired commit log volume for this node.

    • Storage for backup volume in GB: The node’s current backup volume storage value appears in this field. Increase this number to the desired backup volume for this node.

    Note:

    If you enter a value which is larger than the defined limits, or lower than the current value, the field is highlighted in red and a tooltip is displayed explaining the error.

  5. Click Yes, Add Storage.
    The cluster restarts.
Node is updated with the new storage size and the updated values are displayed in the Service Overview.

Note:

It is not possible to shrink a storage volume.
