iXsystems is pleased to announce the general availability of TrueNAS 12.0-U1! This is the first maintenance release of the unified FreeNAS and TrueNAS release that has been renamed to TrueNAS CORE and TrueNAS Enterprise, respectively. Since 12.0-Release was launched on Oct 20th over 180 new improvements or bug fixes have been merged in time for the U1 release!

  • Enclosure Management has been improved with support for new TrueNAS R-Series systems (NAS-108167)! The R-Series is a new TrueNAS hardware line from iXsystems that is designed to provide maximum storage potential at minimum cost.
  • OAuth support has been added for Gmail (NAS-104374). This is to help users prepare for Google’s eventual disabling of less secure app (LSA) access to Google Workspace applications.
  • The SNMP service has been expanded to allow tracking IP bandwidth per client (NAS-108068)! By opening the SNMP service options and enabling Network Performance Statistics, you can receive these additional statistics in future SNMP messages.
  • Fusion Pools have added a threshold for adding small blocks of data to the metadata vdev (NAS-107651). When the storage pool has a metadata vdev, you can set the block size threshold on each dataset by opening the dataset advanced options and finding the Metadata (Special) Small Block Size field.
  • Automatic TRIM has been added as a new pool option (NAS-107694). When enabled, TrueNAS will periodically check disks in the pool for data blocks that can be reclaimed. This can have a performance impact, so it is disabled by default. For more details about TRIM in ZFS, see the autotrim property description in zpool.8.
  • The Reporting page display issue for different themes has been fixed (NAS-108032)
  • An issue with SNMP that resulted in the system drastically consuming CPU resources has been fixed (NAS-108050). This issue also led to merging related performance improvements in the upstream OpenZFS repository.
  • Included in this release is OpenZFS 2.0! This update to the TrueNAS filesystem unified the Unix and Linux code bases of ZFS and added new filesystem level features like sequential resilvering, ZStandard compression, and persistent L2ARC.

With the U1 release, TrueNAS Enterprise customers can begin manually updating their systems to TrueNAS 12.0. For assistance with the Enterprise update process, please contact iX Support.

Known Issues

KeySummaryWorkaround
NAS-108627An underlying ZFS issue can cuase data corruption.A bug in the Asynchronous Copy-on-Write code can cause data corruption when upgrading certain systems.
NAS-107151Replication fails between legacy TrueNAS 9.10 systems and 12.0-BETA1 systems.Due to numerous improvements in the replication engine and ZFS, FreeNAS/TrueNAS 9.10 systems (or earlier) can no longer replicate to or from TrueNAS 12.0. Update the legacy TrueNAS system to FreeNAS/TrueNAS 11.3 or newer.
NAS-106992Persistent L2ARC is disabled by default due to performance impact when rebuilding with large amounts of data.Reactivating persistent L2ARC can result in degraded UI and Middleware performance in specific situations where large amounts of data is loaded into L2ARC and a rebuild is triggered. To 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.
NAS-108580U1 update is incorrectly flagged as "Not a Production Release"This warning is a result of the Enterprise train not being activated yet and can be safely ignored. This will be automatically corrected on February 2nd, 2021 when the Enterprise update train is activated.
Performance regressions on some Intel and Chelsio Cards vs 11.X SeriesOur team is aware of some performance regressions when using Intel and Chelsio Network Devices on TrueNAS 12.0. These issues have been identified in upstream FreeBSD 12.X and work is now being done to resolve those issues. A hotfix release will be issued when complete.
