To increase size in a pvc, decrease size is not suppported:

kubectl patch pvc elasticsearch-master-elasticsearch-master-0 -p '{"spec":{"resources":{"requests":{"storage":"35Gi"}}}}'
persistentvolumeclaim/elasticsearch-master-elasticsearch-master-0 patched
kubectl patch pvc elasticsearch-master-elasticsearch-master-1 -p '{"spec":{"resources":{"requests":{"storage":"35Gi"}}}}'
Error from server (Forbidden): persistentvolumeclaims "elasticsearch-master-elasticsearch-master-1" is forbidden: only dynamically provisioned pvc can be resized and the storageclass that provisions the pvc must support resize

Solution: ensure your StorageClass has AllowVolumeExpansion:  True defined. Can be modified or added without loosing data.

Minikube

kubectl -n default patch pvc data-my-mariadb-0 -p '{"spec":{"resources":{"requests":{"storage":"16Gi"}}}}'
Error from server (Forbidden): persistentvolumeclaims "data-my-mariadb-0" is forbidden: only dynamically provisioned pvc can be resized and the storageclass that provisions the pvc must support resize


kubectl describe sc standard| grep AllowVolumeExpansion
AllowVolumeExpansion:  True
