5.2. Expanding CSI volumes
You can use the Container Storage Interface (CSI) to expand storage volumes after they have already been created.
OpenShift Container Platform supports CSI volume expansion by default. However, a specific CSI driver is required.
OpenShift Container Platform 4.5 supports version 1.1.0 of the CSI specification.
Expanding CSI volumes is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
