The Disks screen lists the physical drives (disks) installed in the system. The list includes the names, serial numbers, sizes, and pools for each system disk.

Use the Columns dropdown list to select options to customize the information displayed. Options are Select All, Name, Serial (the disk serial number), Disk Size, Pool (where the disk is in use), Disk Type, Description, Model, Transfer Mode, Rotation Rate (RPM), HDD Standby, Adv. Power Management, and Reset to Defaults. Each option displays the information you enter in the Edit Disk screen or when you install the disk.

Datasets, root, non-root parent, and child, or zvols with encryption include the Encryption widget in the set of dataset widgets shown on the Datasets screen.

The Datasets tree table includes lock icons and descriptions that indicate the encryption state of datasets.

Icon	State	Description
	Locked	Displays for locked encrypted root, non-root parent and child datasets.
	Unlocked	Displays for unlocked encrypted root, non-root parent and child datasets.
	Locked by ancestor	Displays for locked datasets that inherit encryption properties from the parent.
	Unlocked by ancestor	Displays for unlocked datasets that inherit encryption properties from the parent.

The Encryption option on the Pool Manager screen sets encryption for the entire pool.

This tutorial covers migrating data and configuration from one local pool to another on a TrueNAS storage appliance. Migrating is helpful if, for example, when you have two local pools (Pool A and Pool B) and want to consolidate them by moving data and shares from Pool B to Pool A. You can then destroy Pool B and repurpose its drives.

The Storage Dashboard screen allows users to configure and manage storage resources such as pools (VDEVs) and disks. The dashboard widgets organize functions related to storage resources.

The No Pools screen displays before you add the first pool.

TrueNAS Enterprise

Storage Tiering is only available on TrueNAS Enterprise systems.

This tutorial covers how to use the ZFS storage tiering feature introduced in TrueNAS 26 to migrate a TrueNAS Enterprise storage appliance from a two-pool configuration (for example, an HDD pool with a mirrored special vdev and a separate SSD pool) to a single tiered pool.

The Pool Creation Wizard configuration screens include a configuration preview and an inventory list of disks available on the system.

Create Pool at the top right of the Storage Dashboard screen opens the Pool Creation Wizard.

Configuration Preview lists pool and VDEV settings that dynamically update as you configure settings in the wizard.

Unassigned Disks shows the number of available disks by size on the system. This list dynamically updates as disks move to VDEVs added in the wizard.

The Advanced Settings screen provides configuration options for the console, syslog, audit, kernel, sysctl, storage (system dataset pool), replication, WebSocket sessions, cron jobs, init/shutdown scripts, NTP servers, allowed IP addresses, isolated GPU device(s), self-encrypting drives, and global two-factor authentication.
