MAAS 2.3.0 (alpha3)New Features & ImprovementsHardware Testing (backend
only)

MAAS has now introduced an improved hardware testing framework. This new
framework allows MAAS to test individual components of a single machine, as
well as providing better feedback to the user for each of those tests. This
feature has introduced:


   -

   Ability to define a custom testing script with a YAML definition - Each
   custom test can be defined with YAML that will provide information about
   the test. This information includes the script name, description, required
   packages, and other metadata about what information the script will gather.
   This information can then be displayed in the UI.
   -

   Ability to pass parameters - Adds the ability to pass specific
   parameters to the scripts. For example, in upcoming beta releases, users
   would be able to select which disks they want to test if they don't want to
   test all disks.
   -

   Running test individually - Improves the way how hardware tests are run
   per component. This allows MAAS to run tests against any individual
   component (such a single disk).
   -

   Adding additional performance tests
   -

      Added a CPU performance test with 7z.
      -

      Added a storage performance test with fio.


Please note that individual results for each of the components is currently
only available over the API. Upcoming beta release will include various UI
improvements that will allow the user to better surface and interface with
these new features.
Rack Controller Deployment in Whitebox Switches

MAAS has now the ability to install and configure a MAAS rack controller
once a machine has been deployed. As of today, this feature is only
available when MAAS detects the machine is a whitebox switch. As such, all
MAAS certified whitebox switches will be deployed with a MAAS rack
controller. Currently certified switches include the Wedge 100 and the
Wedge 40.

Please note that this features makes use of the MAAS snap to configure the
rack controller on the deployed machine. Since snap store mirrors are not
yet available, this will require the machine to have access to the internet
to be able to install the MAAS snap.
Improved DNS Reloading

This new release introduces various improvements to the DNS reload
mechanism. This allows MAAS to be smarter about when to reload DNS after
changes have been automatically detected or made.
UI - Controller Versions & Notifications

MAAS now surfaces the version of each running controller, and notifies the
users of any version mismatch between the region and rack controllers. This
helps administrators identify mismatches when upgrading their MAAS on a
multi-node MAAS cluster, such as a HA setup.
