SCALE 20.10-ALPHA (Angelfish)

  11 minute read

October 16, 2020

iXsystems is pleased to release the first Alpha version of TrueNAS SCALE! SCALE is the newest member of the TrueNAS software family. When complete, SCALE will have all major TrueNAS CORE storage and sharing features and web interface based on Debian GNU/Linux. There will also be additional SCALE-specific features that are derived from the application’s Linux base. The major features of SCALE are represented in the application acronym:

  • Scaled-Out ZFS
  • Converged
  • Active-Active
  • Linux Containers
  • Easy to Manage

Initial developer’s notes for TrueNAS SCALE are available on the TrueNAS Documentation Hub at Note that because SCALE shares the same UI as the FreeBSD-based TrueNAS CORE, many of the current documentation articles also apply to SCALE. SCALE feature-specific articles will be added to as the software approaches its first full release.

Code-named Angelfish, TrueNAS SCALE-ALPHA will be following a year.month scheme for versioned releases. Because this is an ALPHA release of the software, not all planned features are present. The status of major features are listed here, along with the full changelog of bug fixes that are part of the SCALE 20.10-ALPHA release.



Verified Features are generally working in SCALE. Minor bugs could be present.

  • Pool Management
  • SMB Shares
  • iSCSI Shares
  • NFS Shares
  • S3 Shares
  • AFP Shares
  • Online / Offline updating
  • Virtual Machines (Using KVM)
  • WebDAV
  • Monitoring, Alerting and Reporting


These features have been added, but have known issues or are not fully feature-complete. Please use only with caution.

  • Cloud Sync Tasks
  • Docker with Kubernetes (CLI)
  • Docker with NVIDIA gpu passthrough flags (CLI)
  • AD / LDAP Directory Services
  • Wireguard (CLI)
  • Networking and Settings UX Refresh


These features are still in early development and will be landing in Nightly images of SCALE in the near future.

  • Applications UI
  • Clustered Datasets API support for TrueCommand
  • TrueCommand Clustering UI for SCALE
  • POSIX 1e / NFSv4 ACL support


As the root user, it is possible to load additional software via the apt package manager commands. This is useful for developers on experimental systems who are trying new features or diagnosing issues. Installing the wrong packages could render a system non-functional and caution should be taken.

Packages downloaded via apt are not persistent. They will not survive an upgrade and may negatively impact normal operation. Users of operational systems should not use the apt command unless advised by the developers. For persistence between upgrades, users should deploy custom packages as containers.
