When a single APFS container has multiple volumes, the container’s miễn phí space is shared and automatically allocated đồ sộ any of the individual volumes as needed. If desired, you can specify reserve and quota sizes for each volume. Each volume uses only part of the overall container, so sánh the available space is the total size of the container, minus the size of all the volumes in the container.
