Documentation Archive

Welcome to the Documentation Archive!

iXsystems employees maintain documentation and provide regular updates for current and in development (future) versions of TrueNAS software. For documentation purposes, current and future releases are those recommended by the TrueNAS Software Status page for one or more user type.

Documentation for previous releases, that are no longer recommended for any user type, is archived and unmaintained.

All documentation provided here is end-of-life (EoL), intended for reference only, and no longer receives any updates.

Software releases after TrueNAS 22.12 (Bluefin) are available as navigable website branches. Earlier releases are available only in PDF.

12.0 NVDIMM Alert

Some TrueNAS M-Series systems installed with 12.0 releases with some 16GB 2666mhz NVDIMMs can see an alert that warns the NVDIMM firmware is out of date:

This can be a false positive that has been fixed in TrueNAS 13.0-U1 (see NAS-116986). Upgrading to an Enterprise-recommended release of TrueNAS 13.0 resolves this alert. To help determine if the deployment is ready to upgrade to TrueNAS 13.0, please refer to the current TrueNAS Software Status and, when your use case matches a recommended 13.0 release, contact iXsystems Support to schedule an upgrade.

The documentation, release notes, and notices provided in this section follow the major and minor releases of the previous FreeNAS and TrueNAS projects, before their unification under the TrueNAS name. At that time, FreeNAS published first and TrueNAS followed later in the FreeNAS lifecycle with occasional simultaneous releases. TrueNAS releases took all the FreeNAS changes up to that point and added a few Enterprise feature-specific (High Availability) changes.
