Updating SCALE

TrueNAS has several software branches (linear update paths) known as trains. SCALE is currently a Prerelease Train. Prerelease Trains have various preview/early build releases of the software.

SCALE has several trains available for updates. However, the web interface only displays trains you can select as an upgrade. To view a list of the available trains, click on the arrow to the right of your current train.

For more information on other available trains, see TrueNAS Upgrades.

See the Software Status page for the latest recommendations for software usage. Bluefin and Nightlies are non-production trains. If you are using a non-production train, be prepared to experience bugs or problems. Testers are encouraged to submit bug reports and debug files at https://jira.ixsystems.com.

The TrueNAS SCALE Update screen lets users update their system using two different methods: manual or automatic.

We recommend updating TrueNAS when the system is idle (no clients connected, no disk activity, etc). Most updates require a system reboot.

Update during scheduled maintenance times to avoid disrupting user activities.

All auxiliary parameters are subject to change between major versions of TrueNAS due to security and development issues. We recommend removing all auxiliary parameters from TrueNAS configurations before upgrading.

Select the Check for Updates Daily and Download if Available option to automatically download updates.

If an update is available, click Apply Pending Update to install it.

To do a manual update, click Download Updates and wait for the file to download to your system.

Download the SCALE Manual Update File.

To manually update TrueNAS, click Install Manual Update File and save your configuration.

Select a temporary location to store the update file and click Choose File. Select the .iso you want to upgrade to and click Apply Update.
