Reinstalling MSDP Scaleout operator

When you undeploy MSDP Scaleout operator, the MSDP Scaleout CRD is removed from the cluster. It also deletes all the existing MSDP Scaleout on the cluster. The PVC for the operator logs is also deleted. However, the MSDP Scaleout critical data and metadata is not deleted.

To reinstall MSDP Scaleout operator

  1. Run the following command to delete the MSDP Scaleout operator:

    kubectl msdp delete [-k] [-n <sample-operator-namespace>]

  2. Run the following command to redeploy the operator.
    # helm upgrade --install operators operators-<version>.tgz \
      --create-namespace \
      --namespace netbackup-operator-system \
      --set global.platform=${platform} \
      --set global.operatorNamespace=netbackup-operator-system \
      --set global.containerRegistry="$REGISTRY" \
      --set global.storage.eks.fileSystemId=${EFS_ID} \
      --set msdp-operator.image.name="$MSDP_OPERATOR_IMAGE_NAME" \
      --set msdp-operator.image.tag="$MSDP_OPERATOR_IMAGE_TAG" \
      --set msdp-operator.storageClass.name=nb-disk-standardssd \
      --set msdp-operator.storageClass.size=5Gi \
      --set msdp-operator.logging.debug=false \
      --set msdp-operator.logging.age=28 \
      --set msdp-operator.logging.num=20 \
      --set msdp-operator.nodeSelector."${MSDP_NODE_SELECTOR_KEY//./\\.}"="${MSDP_NODE_SELECTOR_VALUE}" \
      --set nb-operator.image.name="$OPERATOR_IMAGE_NAME" \
      --set nb-operator.image.tag="$OPERATOR_IMAGE_TAG" \
      --set nb-operator.loglevel.value="0" \
      --set nb-operator.nodeSelector.node_selector_key="$MEDIA_NODE_SELECTOR_KEY" \
      --set nb-operator.nodeSelector.node_selector_value="$MEDIA_NODE_SELECTOR_VALUE" \
      --set flexsnap-operator.image.name="$FLEXSNAP_OPERATOR_IMAGE_NAME" \
      --set flexsnap-operator.image.tag="$FLEXSNAP_OPERATOR_IMAGE_TAG" \
      --set flexsnap-operator.nodeSelector.node_selector_key="$MEDIA_NODE_SELECTOR_KEY" \
      --set flexsnap-operator.nodeSelector.node_selector_value="$MEDIA_NODE_SELECTOR_VALUE"
  3. If the reclaim policy of the storage class is Retain, run the following command to restart the existing MSDP Scaleout. MSDP Scaleout starts with the existing data/metadata.

    kubectl apply -f <your-cr-yaml>
