-It's not supported to reduce the size of a PVC (to prevent data loss). You can edit an existing storage class using the `kubectl edit sc` command, or you can create your own custom storage class. For example, if you want to use a disk of size 4 TiB, you must create a storage class that defines `cachingmode: None` because [disk caching isn't supported for disks 4 TiB and larger][disk-host-cache-setting].
