You can view the details of a storage pool to determine where the storage pool is used and to see which nodes and storage grades are included.

Before you begin

  • You are signed in to the Grid Manager using a supported web browser.

  • You have specific access permissions.

Steps

  1. Select ILM > Storage pools.

    The Storage pools table includes the following information for each storage pool that includes Storage Nodes:

    • Name: The unique display name of the storage pool.

    • Node count: The number of nodes in the storage pool.

    • Storage usage: The percentage of the total usable space that has been used for object data on this node. This value does not include object metadata.

    • Total capacity: The size of the storage pool, which equals the total amount of usable space for object data for all nodes in the storage pool.

    • ILM usage: How the storage pool is currently being used. A storage pool might be unused or it might be used in one or more ILM rules, erasure coding profiles, or both.

      Note You can't remove a storage pool if it is being used.

  2. To view details about a specific storage pool, select its name.

    The details page for the storage pool appears.

  3. View the Nodes tab to learn about the Storage Nodes or Archive Nodes included in the storage pool.

    The table includes the following information for each node:

    • Node name

    • Site name

    • Storage grade

    • Storage usage (%): The percentage of the total usable space for object data that has been used for the Storage Node. This field is not visible for Archive Node pools.

      Note The same Storage usage (%) value is also shown in the Storage Used - Object Data chart for each Storage Node (select NODES > Storage Node > Storage).

  4. Select the ILM usage tab to determine if the storage pool is currently being used in any ILM rules or erasure coding profiles.

  5. Optionally, go to the ILM rules page to learn about and manage any rules that use the storage pool.

    See the instructions for working with ILM rules.
