Volume expansion was introduced as a alpha feature in Kubernetes 1.8 and it went beta in 1.11 and with Kubernetes 1.24 we are excited to announce general availability(GA) of volume expansion.
This feature allows Kubernetes users to simply edit their
PersistentVolumeClaim objects and specify new size in
PVC Spec and Kubernetes will automatically expand the volume using
storage backend and also expand the underlying file system in-use
by the Pod without requiring any downtime at all if possible.
