Adding data volumes
You can add the data volumes by updating the Cloud Scale helm release.
To add the data volumes by updating the Cloud Scale helm release
- Run the following command to obtain the Cloud Scale release name:
Helm ls -n <namespace>
- Navigate to the helm directory within the extracted tar location.
- Run the following command to add new data volume:
helm upgrade <cloudscale release name> cloudscale-<version>.tgz -n netbackup --reuse-values
--set environment.msdpScaleouts.storage.dataVolumes[0].capacity=<existing volume capacity>
--set environment.msdpScaleouts.storage.dataVolumes[0].storageClassName=<<existing volume storage class>
--set environment.msdpScaleouts.storage.dataVolumes[1].capacity=<capacity for new volume>
--set environment.msdpScaleouts.storage.dataVolumes[1].storageClassName=<storage class for new volume>
Each MSDP engine can support up to 16 data volumes.
It is recommended that you use the same data volume size if you add multiple volumes.
Note:
Due to some Kubernetes restrictions, MSDP operator restarts the engine pods for attaching the existing and new volumes, which can cause the short downtime of the services.
