      MSDP Scaleout CR

Expanding existing data or catalog volumes

You can expand the existing data or catalog volumes by updating the CR.

To expand the data or catalog volumes by updating the CR YAML file

  1. Open the CR YAML file to edit.
  2. Increase the requested storage size in the spec.dataVolumes field or in the spec.catalogVolume field.
  3. Apply new CR YAML to update the CR in the Kubernetes environment.

    kubectl apply -f <your-cr-yaml>

To expand the data or catalog volumes using the kubectl command directly

  • Run the following command to increase the requested storage size in the spec.dataVolumes field or in the spec.catalogVolume field..

    kubectl -n <sample-namespace> edit msdpscaleout <your-cr-name> [-o json | yaml]

Sometimes Azure disk CSI driver may not respond the volume expansion request promptly. In this case, the operator retries the request by adding 1 byte to the requested volume size to trigger the volume expansion again. If it is successful, the actual volume capacity could be slightly larger than the requested size.

Due to the limitation of Azure disk CSI storage driver, the engine pods need to be restarted for resizing the existing volumes. This can cause the short downtime of the services.

MSDP Scaleout does not support the following:

  • Cannot shrink the volume size.

  • Cannot change the existing data volumes other than for storage expansion.

  • Cannot expand the log volume size. You can do it manually. See Manual storage expansion.

  • Cannot expand the data volume size for MDS pods. You can do it manually. See Manual storage expansion.
