Managing the default storage class allows you to accomplish several different objectives:
-
Enforcing static provisioning by disabling dynamic provisioning.
-
When you have other preferred storage classes, preventing the storage operator from re-creating the initial default storage class.
-
Renaming, or otherwise changing, the default storage class
To accomplish these objectives, you change the setting for the spec.storageClassState field in the ClusterCSIDriver object. The possible settings for this field are:
-
Managed: (Default) The Container Storage Interface (CSI) operator is actively managing its default storage class, so that most manual changes made by a cluster administrator to the default storage class are removed, and the default storage class is continuously re-created if you attempt to manually delete it.
-
Unmanaged: You can modify the default storage class. The CSI operator is not actively managing storage classes, so that it is not reconciling the default storage class it creates automatically.
-
Removed: The CSI operators deletes the default storage class.
Managing the default storage classes is supported by the following Container Storage Interface (CSI) driver operators:
