iXsystems is pleased to announce the general availability of TrueNAS 12.0-U8.1!

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-U8 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 system health, configuration, and support the upgrade process as part of the “white glove” service that comes with any support contract.

Customers who purchase iXsystems hardware or that want additional support must have a support contract to use iXsystems Support Services. The TrueNAS Community forums provides free support for users without an iXsystems Support contract.

    Known Issues

    NAS-113284Samba CVE-2021-20316: Symlink race error can allow metadata read and modify outside of the exported share.Do not enable SMB1 (this is disabled by default in TrueNAS 11.2 and later). If SMB1 must be enabled for backwards compatibility then add the auxiliary parameter: unix extensions = no to the Services > SMB configuration form and restart the service.
    For versions prior to TrueNAS 13.0, we recommend only exporting areas of the file system by either SMB2 or NFS, not both.
    Minio Project: Certificate errors in distributed mode with docker composeWild card certificates do not work with MinioReset the Minio domain configuration to localhost when the Minio SAN/CN configuration is empty except for a wildcard domain.
    Asigra Plugin UpgradesAsigra users running version 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.
