====== ZFS - Pools - Create a Dataset within the Pool ======
A Dataset is a Filesystem, or in essence a Directory.
sudo zfs create testpool/dataset
**NOTE:** The size of the Dataset does not need to be specified.
* The free space is handled by ZFS.
* So there is no need to have to resize partitions when you start running out of space on one.
* If more than one disk is being used, this also provides software RAID features like mirror, stripe and parity.
