• A new kfuse-ssd-offline storage class has been introduced in Kfuse version 2.6. This storage class uses gp3 on AWS, pd-balanced on GCP, and Standard_LRS on Azure. This is now the default storage class for Pinot Offline Servers, which should give better disk IO performance.

• If the custom values yaml is already set to use the specified disk type (e.g., kfuse-ssd-aws-gp3 or standard-rwo on GCP), then the remaining steps can be skipped.

• If the custom values yaml does not explicitly set the pinot.server.offline.persistence.storageClass field or it is set to a different storage class. Ensure that the field is not set in the custom values yaml. Then run the following commands

  Code Block
  kubectl delete sts -n kfuse pinot-server-offline kubectl delete pvc -l app.kubernetes.io/instance=kfuse -l component=server-offline -n kfuse

• Note that the above commands corresponds to the corresponding PVCs of the Pinot offline servers. After upgrade to Kfuse version 2.6, PVCs with the desired storage class will be created for the Pinot offline servers.
