Describe the bug On ZFS systems Disks section in Summary currently lists each dataset and shows disk avail / size as reported by df. However, df reports the space remaining in the entire pool under Avail for each dataset. This gives a distorted view of the storage situation on a particular endpoint.

To Reproduce (see above description)

Expected behavior The data reported by zpool list would be more appropriate here.
