TrueNAS 12.0-U6 was released today and is now the recommended update for even the most conservative users of both TrueNAS CORE and TrueNAS Enterprise. With this release comes the resolution of approximately 90 issues, including:

  • User/Group default quotas have been updated to display properly
  • NFSv4 HA improvements
  • More extensive SMB regression testing with various SMB options
  • SMB shadow copies have been fixed (bug in U5)
  • OpenZFS dedup performance improvements by defaulting to SHA-512 algorithm
  • Better webUI snapshot filtering by name
  • UI improvements for disk temperature monitoring and UEFI booting
  • Ongoing improvements to UI & middleware performance for large drive counts
  • Improved UI for plugin updates/upgrades

TrueNAS 12.0-U5 and U5.1 were the most popular releases of TrueNAS ever. Over 75% of the FreeNAS 11.3 installed base has migrated to TrueNAS CORE. TrueNAS 12.0 exceeded one exabyte (EB) of data under management in June and is expected to surpass 2 EB by the end of 2021. The FreeNAS.org website has been redirected to the TrueNAS.com website as an indication of the move of FreeNAS to legacy status.

In addition to improving TrueNAS 12.0 software, we’re also actively partnering with companies that deliver some significant value-add to TrueNAS users. Futurex is announcing today that they have integrated their KMIP management servers with the KMIP capability in TrueNAS 12.0 Enterprise. Later this month, there will be a joint announcement with Nextcloud about collaboration between the TrueNAS and Nextcloud platforms.

For those with FreeNAS installed on your system, we recommend updating or upgrading to FreeNAS 11.3-U5 first and then upgrading to TrueNAS 12.0-U6 with a single click to retain roll-back options. While it is an easy web update, we do recommend waiting to update your system’s zpool feature flags until you are finished validating your performance and functionality.

For those with TrueNAS HA systems and support contracts, we recommend contacting iXsystems Support to schedule an upgrade. We will verify your systems’ health, configuration, and support the upgrade process as part of the “white glove” service that comes with any support contract.

Known Issues

KeySummaryWorkaround
Asigra Plugin UpgradesAsigra users running version 14.2.0.2 or earlier requires a TrueNAS CLI upgrade procedure to update to a new plugin version. In the TrueNAS web interface, open the **Shell** and enter iocage upgrade asigra-plugin-name, replacing asigra-plugin-name with whatever unique name was created for the plugin.
NAS-106992Persistent L2ARC is disabled by default.While the underlying issues have been fixed, this setting continues to be disabled by default for additional performance investigation. To manually reactivate persistent L2ARC, log in to the TrueNAS Web Interface, go to System > Tunables, and add a new tunable with these values:
  • Type = sysctl
  • Variable = vfs.zfs.l2arc.rebuild_enabled
  • Value = 1
TrueNAS "root" user account cannot be an SMB user.This is an intentional change to improve software security and suitability for deployment in a variety of environments. Update the SMB configuration to use a different user account.
