The PC-BSD® Disk Manager can be used to manage ZFS pools and datasets as well as the disks attached to the system. To access this utility, use Control Panel → Disk Manager or type pc-su pc-zmanager from within an xterm. You will need to input your password in order to access this utility.
Managing ZFS Datasets
As seen in the example in Figure 8.13a, the utility will open in the “ZFS Filesystems” tab and will display the system's ZFS datasets, the amount of space available to each dataset, and the amount of space each dataset is using.

The name of the pool in this example is tank. If the system has multiple pools, click the green arrow to select the desired pool.
If you right-click the pool name, the following options are available:
- Create new dataset: Figure 8.13b shows the options that are available when you create a new dataset.
- Create a clone dataset:
- Take a snapshot:
- Edit properties:
Figure 8.13b: Creating a New ZFS Dataset
When creating a new dataset, the "Name" field is pink as a reminder to type in the dataset name immediately after the displayed pool name.
Managing the ZFS Pool
To view the status of the ZFS pools and the disk(s) in the pool, click the "ZFS Pools" tab. In the example, shown in Figure 8.13b, the ZFS pool named tank was created from one disk. The state of "Online" indicates that the pool is healthy.
