<literal>mirror</literal> - Mirroring stores a complete copy of all data on every disk. Mirroring provides a good read perfomance because data is read from all disks in parallel. Write performance is slower as the data must be written to all disks in the pool. Allows all but one disk to fail. This option requires at least two disks.

<literal>Pool Type/Disks</literal> - Allow to configure the <literal>Pool Type</literal> and the disk(s) that will constitute the pool. The automatic <acronym>ZFS</acronym> installer currently only supports the creation of a single top level vdev, except in stripe mode. To create more complex pools, use the instructions in <xref linkend="bsdinstall-part-shell"/> to create the pool.
<literal>Rescan Devices</literal> - Repopulate the list of available disks.
<literal>Disk Info</literal> - Disk Info menu can be used to inspect each disk, including its partition table and various other information such as the device model number and serial number, if available.
<literal>Pool Name</literal> - Establish the name of the pool. The default name is <emphasis>zroot</emphasis>.
<literal>Force 4K Sectors?</literal> - Force the use of 4K sectors. By default, the installer will automatically create partitions aligned to 4K boundaries and force ZFS to use 4K sectors. This is safe even with 512 byte sector disks, and has the added benefit of ensuring that pools created on 512 byte disks will be able to have 4K sector disks added in the future, either as additional storage space or as replacements for failed disks. Press the <keycap>Enter</keycap> key to chose to activate it or not.
<literal>Encrypt Disks?</literal> - Encrypting the disks allows the user to encrypt the disks using <acronym>GELI</acronym>. More information about disk encryption is available in <xref linkend="disks-encrypting-geli"/>. Press the <keycap>Enter</keycap> key to chose activate it or not.
<literal>Partition Scheme</literal> - Allow to choose the partition scheme. GPT is the recommended option in most cases. Press the <keycap>Enter</keycap> key to chose between the different options.
<literal>Swap Size</literal> - Establish the amount of swap space.
<literal>Mirror Swap?</literal> - Allows the user to mirror the swap between the disks. Be aware, enabling mirror swap will break crash dumps. Press the <keycap>Enter</keycap> key to activate it or not.
<literal>Encrypt Swap?</literal> - Allow the user the possibility to encrypt the swap. Encrypts the swap with a temporary key each time that the system boots and discards it on reboot. Press the <keycap>Enter</keycap> key to chose activate it or not. More information about swap encryption in <xref linkend="swap-encrypting"/>.
Select <keycap>T</keycap> to configure the <literal>Pool Type</literal> and the disk(s) that will constitute the pool.

_ external ref='bsdinstall/bsdinstall-zfs-vdev_type' md5='__failed__'
Here is a summary of the <literal>Pool Type</literal> which can be selected in this menu:
<literal>stripe</literal> - Striping provides maximum storage of all connected devices, but no redundancy. If just one disk fails the data on the pool is lost irrevocably.
<literal>mirror</literal> - Mirroring stores a complete copy of all data on every disk. Mirroring provides a good read perfomance because data is read from all disks in parallel. Write performance is slower as the data must be written to all disks in the pool. Allows all but one disk to fail. This option requires at least two disks.
<literal>raid10</literal> - Striped mirrors. Provides the best performance, but the least storage. This option needs at least an even number of disks and a minimum of four disks.
<literal>raidz1</literal> - Single Redundant RAID. Allow one disk to fail concurrently. This option needs at least three disks.
<literal>raidz2</literal> - Double Redundant RAID. Allows two disks to fail concurrently. This option needs at least four disks.
<literal>raidz3</literal> - Triple Redundant RAID. Allows three disks to fail concurrently. This option needs at least five disks.
Once a <literal>Pool Type</literal> has been selected, a list of available disks is displayed, and the user is prompted to select one or more disks to make up the pool. The configuration is then validated, to ensure enough disks are selected. If not, select <guibutton>&lt;Change Selection&gt;</guibutton> to return to the list of disks, or <guibutton>&lt;Back&gt;</guibutton> to change the <literal>Pool Type</literal>.
Disk Selection

Invalid Selection
_ external ref='bsdinstall/bsdinstall-zfs-vdev_invalid' md5='__failed__'
If one or more disks are missing from the list, or if disks were attached after the installer was started, select <guibutton>- Rescan Devices</guibutton> to repopulate the list of available disks.
Rescan Devices
_ external ref='bsdinstall/bsdinstall-zfs-rescan-devices' md5='__failed__'
To avoid accidentally erasing the wrong disk, the <guibutton>- Disk Info</guibutton> menu can be used to inspect each disk, including its partition table and various other information such as the device model number and serial number, if available.
