capacityMin

(string: <optional>) - Option for requesting a minimum capacity, in bytes. The capacity of a volume may be the physical size of a disk, or a quota, depending on the plugin. The specific size of the resulting volume is somewhere between capacity_min and capacity_max; the exact behavior is up to the plugin. If you want to specify an exact size, set capacity_min and capacity_max to the same value. Accepts human-friendly suffixes such as "100GiB". Plugins that cannot restrict the size of volumes may ignore this field.
