摘要： A first command is received from a workload, by a host system executing a nested container storage interface (CSI) driver, to create a persistent volume. The nested CSI driver converts the first command used by the workload to create the persistent volume to a second command used by the host system to increase a capacity of a previously generated persistent volume allocated to the workload. The second command is transmitted to an undercluster CSI driver of the host system, wherein the second command causes the undercluster CSI driver to increase the capacity of the previously generated persistent volume.
