Remove FabricPool data from StorageGRID

Contributors

If you need to remove the FabricPool data that is currently stored in StorageGRID, you must use ONTAP to retrieve all data for the FabricPool volume and promote it to the performance tier.

Before you begin
About this task

These instructions explain how to move data from StorageGRID back to FabricPool. You perform this procedure using ONTAP and StorageGRID Tenant Manager.

Steps

  1. From ONTAP, issue the volume modify command.

    Set tiering-policy to none to stop new tiering and set cloud-retrieval-policy to promote to return all data that was previously tiered to StorageGRID.

    See Promote all data from a FabricPool volume to the performance tier.

  2. Wait for the operation to complete.

    You can use the volume object-store command with the tiering option to check the status of the performance tier promotion.

  3. When the promote operation is complete, sign in to StorageGRID Tenant Manager for the FabricPool tenant account.

  4. Select View buckets from the dashboard, or select STORAGE (S3) > Buckets.

  5. Confirm that the FabricPool bucket is now empty.

  6. If the bucket is empty, delete the bucket.

After you finish

When you delete the bucket, tiering from FabricPool to StorageGRID can no longer continue. However, because the local tier is still attached to the StorageGRID cloud tier, ONTAP System Manager will return error messages indicating that the bucket is inaccessible.

To prevent these error messages, do either of the following:

  • Use FabricPool Mirror to attach a different cloud tier to the aggregate.

  • Move the data from the FabricPool aggregate to a non-FabricPool aggregate and then delete the unused aggregate.

See the ONTAP documentation for FabricPool for instructions.
