kubectl edit pvc influxdb-data-influxdb-0 -n influxdb  #edit size
kubectl delete sts --cascade=orphan influxdb -n influxdb
helm upgrade --install influxdb influxdata/influxdb -f v1/values.yaml --namespace influxdb
kubectl -n influxdb exec -it influxdb-0 -- df -h | grep influx
 kubectl rollout restart sts influxdb -n influxdb

kubectl -n influxdb exec -it influxdb-0 -- df -h | grep influx
kubectl get pvc -A | grep influx

Error: UPGRADE FAILED: cannot patch "influxdb" with kind StatefulSet: StatefulSet.apps "influxdb" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'template', 'updateStrategy', 'persistentVolumeClaimRetentionPolicy' and 'minReadySeconds' are forbidden

Use kubectl delete to delete the StatefulSet. Make sure to supply the --cascade=orphan parameter to the command. This parameter tells Kubernetes to only delete the StatefulSet, and to not delete any of its Pods.

Kubegres looks like it works in azure if you edit pvc size direct.
