ZFS - Datasets - Create a Dataset within a Pool

sudo zfs create testpool/some_dataset
 
or
 
sudo zfs create testpool/some_directory

NOTE: A cool feature of the Volumes is that the size of the partition 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 you are using more than one disk, this also provides software RAID features like mirror, stripe and parity.

Children Datasets

Datasets can have sub-sets (sub-directories):

pool/parent/child
