1) List your PVCs:

kubectl get pvc -A
NAMESPACE    NAME                                          STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
dev          elasticsearch-master-elasticsearch-master-0   Bound    pvc-25c6e973-8fc4-463b-9288-123456678903   30Gi       RWO            standard       2y234d

2) Review your StorageClass has AllowVolumeExpansion configured to true.

kubectl describe sc standard | grep AllowVolumeExpansion
AllowVolumeExpansion:  True

3) Request new size

  • kubectl -n your-namespace patch pvc your-pvc-name -p '{"spec":{"resources":{"requests":{"storage":"16Gi"}}}}}'

4) Verify it
