Storage Dashboard Screen
9 minute read.
Last Modified 2023-08-31 13:31 EDTSCALE Bluefin introduces the new Storage Dashboard screen that is designed to help users configure and manage storage resources such as pools (VDEVs), datasets, and disks, and to keep the pool healthy (scrub). This dashboard uses widgets to organize functions directly or indirectly related to storage resources.
The Storage Dashboard displays the No Pools screen with a Create Pool button in the center of the screen until you add a pool.
Both the Create Pool button on the top right and at the center of the screen open the Create Pool > Pool Manager configuration screen.
After adding a pool, the screen displays five widgets. The Unassigned Disks widget remains at the top of the dashboard and the other four are a set that display for each pool created on the system.
Import at the top of the dashboard opens the Import Pool screen.
Disks at the top of the dashboard opens the Disks screen. The Manage Disks button on the Disk Health widget opens the same Disks screen.
Export/Disconnect opens the Export/disconnect pool window that allows you to either completely remove a pool and deleted all the contents of that pool, or to export the pool to the server and disconnect it in TrueNAS SCALE.
Expand opens the Expand pool dialog. Use to expand the selected pool to fit all available disk space.
Each widget in the set of four pool widgets includes a color-coded icon just to the right of the header that indicates the status of the pool as healthy (green checkmark), offline (orange triangle), or in a warning state (purple warning sign).
This same information displays on both the Storage widget and a pool widget you can add to the Dashboard.
The Storage Dashboard widgets organize storage and related functions for each pool.
The Unassigned Disks widget remains at the top of the dashboard and provides the number of available disks on the system to use in pools. Each pool has a set of four widgets: Topology for managing pool virtual devices or VDEVs, Usage for managing datasets and zvols, ZFS Health for managing pool health and pool functions like scrub and auto TRIM, and Disk Health for managing disks and disk health. Each set of pool widgets provides access to screens for each storage type with the information for the pool pre-selected. For example, Manage Devices on the Topology widget opens the Devices screen with the VDEVs configured for that pool and not all pools on the system.
The Unassigned Disks widget displays the number of disks available on your system to use in pools. The disk count includes disks assigned in an exported pool. If you attempt to use a disk assigned in an exported pool a warning message displays that prompts you to select a different disk.
The Add to Pool window allows you to select a disk or disks to add to either a new pool or an existing pool.
The Topology widget provides information on VDEVS configured on the system and the status of the pool.
The Usage widget provides information on the space configured datasets use and the status of pool usage.
The ZFS Health widget provides information on the health of the pool.
The Scrub Pool dialog allows you to perform an unscheduled scrub task. Scrub Pool initiates a check on pool data integrity.
Edit Auto TRIM opens the dialog that allows you to set auto TRIM.
The Disk Health widget provides information on the health of the disks in a pool.
The Pool Manager(/scaleuireference/storage/pools/poolmanagerscreens/) configuration screen displays after clicking Create Pool on the Storage Dashboard or Add VDEV on the Devices screen.
The Create Pool button opens the Create Pool screen with the Pool Manager configuration screen.
Add VDEV on the Devices screen opens the Add Vdevs to Pool screen with the Pool Manager configuration screen for the selected pool.
The Import Pool button opens the Import Pool screen.
Select a pool from the Pool dropdown list TrueNAS detects as present on the system but that is not yet connected in TrueNAS.
Import starts the process to connect the pool in TrueNAS and bring it into SCALE. Import also reconnects pools after users reinstall or upgrade their TrueNAS system.
Export/Disconnect opens the Export/disconnect pool: poolname window that allows users to export, disconnect, or delete a pool.
Select Expand Pool to increase the pool size to match all available disk space. Users with pools using virtual disks use this option to resize these virtual disks apart from TrueNAS.
