TrueCommand 3.0 Manages ZFS Replication


December 21, 2023

TrueCommand simplifies the operation and fleet management of any environment with more than one TrueNAS Enterprise or Community Edition (CORE, SCALE) system. The release of TrueCommand 3.0 makes it possible to manage ZFS replication between TrueNAS systems and also brings support for systems running TrueNAS SCALE 23.10. Together, TrueNAS and TrueCommand manage and protect your valuable data.

TrueCommand 3.0 is available as a Docker container or as a cloud service, with all communications secured by an SSH tunnel. TrueCommand can be run as an App on TrueNAS SCALE, but it is recommended to run the TrueCommand App from a system it is not directly managing.

Via a single pane of glass, TrueCommand collects usage and performance data, as well as alerts and activity logs. It performs predictive analytics and understands ZFS concepts, including pools and VDEVs. Inventory, support contacts, and software licensing information are managed centrally. Even in single-system environments, TrueCommand provides monitoring and fault diagnosis capabilities that can simplify operations and reduce problem resolution time.

TrueCommand 3.0 is another major step for TrueCommand and includes nearly 100 improvements, features, and bug fixes. The most notable new capabilities are:

  • Replication Manager: When performing replication between systems, there is a need to coordinate the sending and receiving of ZFS snapshots.  Rather than administering each system independently, TrueCommand can manage the replication setup and ongoing monitoring.

  • TrueNAS SCALE 23.10 support: TrueNAS SCALE 23.10.1 includes a new data collection engine and improved APIs which TrueCommand 3.0 can now understand and use. TrueCommand can still manage both the newer and older TrueNAS systems from the same pane of glass.
  • Fleet Dashboard: The TrueCommand UI has been improved with a new Fleet Dashboard that tracks the status of many systems and their datasets. Identify problems and manage alerts more quickly and easily.

TrueCommand 3.0 has also been thoroughly tested with TrueNAS SCALE Bluefin (22.12) and TrueNAS 13.0. It also supports TrueNAS 12.0 and TrueNAS SCALE Angelfish (22.02) – if you’re running an earlier version of TrueNAS, please upgrade to one of the supported versions above before upgrading your TrueCommand instance.

Obtaining TrueCommand

The Docker version of TrueCommand is available as a free download. TrueCommand itself remains free for systems with 50 or fewer drives. Software and support licenses are available for larger deployments via the iX portal or by contacting iXsystems.

TrueCommand Cloud, a SaaS version, is also available. Existing TrueCommand Cloud accounts will be gradually updated as we ensure quality. TrueCommand Cloud itself is running on TrueNAS SCALE systems in an iXsystems data center.

Thanks to all those who tested and provided feedback to get to this stage. As always, we appreciate feedback and bug reports for this TrueCommand 3.0 release.
