PVC provisioning must be based on a configured storage backend. Therefore, if a PVC has been provisioned on a storage backend, do not change the storage backend.

The name uniquely identifies a storage backend. The name of a storage backend with a PVC provisioned cannot be changed.

After a storage backend is modified, the new configuration applies only to volumes to be provisioned.

Do not perform volume management operations during the modification of a storage backend.

Procedure

Delete the storage backend to be modified. For details, see Deleting a Storage Backend .
Create a storage backend with the same name. For details, see Configuring the Storage Backend . The storage backend name cannot be changed.
