Increasing Persistent Volume Claim (PVC)

B Increasing Persistent Volume Claim (PVC)

Increasing the PVC size to support scalability is a mandatory task and must be performed only after the Helm installation or upgrade is complete.

Note:

The PVC size increment must not be performed during the Helm installation or upgrade.

Perform the following steps to increase the PVC:

Set the ALLOWVOLUMEEXPANSION to True for the Storageclass. The default value is standard.
Run the following command to scale down the statefulset for the namespace.
```
kubectl scale sts provgw-auditor-service --replicas=0 -n <namespace>
```
When the statefulset is scaled down, the pod will go to terminate state.

Run the following command to edit the PVC.

kubectl edit pvc dynamic-auditor-pvc-provgw-auditor-service-0 -n <namespace >

You can change the storage space to the required value and save the details.

spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: standard
  volumeMode: Filesystem
  volumeName: pvc-87978b35-2320-4da5-9ca0-1dae183d29e7
status:
  accessModes:
  - ReadWriteOnce
  capacity:
    storage: 10Gi
  phase: Bound

Run the following command to scale-up the statefulset.
```
kubectl scale sts provgw-auditor-service --replicas=1 -n <namespace>
```
Run the following command to view the increased storage in the pod.
```
kubectl get pvc -n <namespace>
```
