{product-title} is capable of provisioning persistent volumes (PVs) using the Container Storage Interface (CSI) driver for OpenStack Cinder.
Familiarity with persistent storage and configuring CSI volumes is recommended when working with a Container Storage Interface (CSI) Operator and driver.
To create CSI-provisioned PVs that mount to OpenStack Cinder storage assets, {product-title} installs the OpenStack Cinder CSI Driver Operator and the OpenStack Cinder CSI driver in the openshift-cluster-csi-drivers namespace.
-
The OpenStack Cinder CSI Driver Operator provides a CSI storage class that you can use to create PVCs. You can disable this default storage class if desired (see Managing the default storage class).
-
The OpenStack Cinder CSI driver enables you to create and mount OpenStack Cinder PVs.
