Perhaps its me but the docs seems a bit contradicting in terms of whether a manual restart is required after increasing the PVC size:
On one hand:
ECK will update the existing PersistentVolumeClaims accordingly, and recreate the StatefulSet automatically
On the other hand:
If the volume driver does not support
ExpandInUsePersistentVolumes, Pods must be manually deleted after the resize, to be recreated automatically with the expanded filesystem.
ExpandInUsePersistentVolumes is not supported, should we delete the pods manually or the ECK will take care of statefulsets re-creation?
