MAAS 2.3.0 (alpha3)
New Features & Improvements
Hardware 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.
