Chapter 5. Adding annotation to the pre-existing backingstores

Adding the correct annotation to the pre-existing backingstores allows the backingstores backed by object gateways (RGWs) to report its actual and free size. The Multicloud Object Gateway (MCG) can retrieve and use this information.


  1. Log in to the OpenShift Container Platform Web Console.
  2. Click Home → Search.
  3. Search for BackingStore in Resources and click on it.
  4. Beside the S3-compatible BackingStore, click Action Menu (⋮) → Edit annotations.
  5. Add rgw for KEY.
  6. Click Save.
