TrueNAS has announced the release of TrueNAS SCALE 23.10 “Cobia,” the third major release of TrueNAS SCALE. This release brings improvements in quality, functionality, security, and performance.

One of the key highlights of the TrueNAS SCALE 23.10 release is the improvement in Server Message Block (SMB) features. SMB is the most common file sharing protocol and is widely supported on various platforms. The new features in this release include SMB and NFSv4 compatibility, SMB share import from other systems, SMB file sync with 3rd party servers, and fast file copy with ZFS block cloning.

In addition to the SMB features, TrueNAS SCALE 23.10 brings several other enhancements. The infrastructure has been improved with Linux Kernel 6.1 and better hardware support, NVIDIA driver updates, and Netdata backend stats collection. The web interface has also been enhanced with improved Apps and Storage Pool UI, as well as simplified feedback and bug reporting.

TrueNAS SCALE 23.10 also includes updates to ZFS and performance improvements. It features OpenZFS 2.2 with contributions from iXsystems, ZFS block cloning for faster file copies, ZFS dRAID pool layouts, and improved ZFS scrub controls. The release also brings updates to protocols and services such as Samba security and speed improvements, simplified SMB cluster expansion via TrueCommand 3.0 (coming soon), and iSCSI improvements.

TrueNAS 13.1, which is planned for release in early 2024, will inherit some of the improvements from TrueNAS SCALE Cobia. This update will include the SMB and ZFS enhancements implemented and tested in Cobia. Nightly versions of TrueNAS 13.1 are available for testing and contribution to the development process.

TrueNAS SCALE 22.12.4.2 is the final version of Bluefin, and going forward, TrueNAS SCALE 23.10 Cobia will gradually become the recommended version. No further versions of Bluefin are planned. TrueNAS provides options for migrating storage services and VMs from CORE to SCALE, and plugins and jails can be manually replaced with Apps.

The TrueNAS installer can be downloaded from the TrueNAS website or the system update feature within an existing TrueNAS installation.
