MAAS Development Summary – September 29th

Hello MAASters!

This past week, the MAAS team met face to face in NYC! The week was concentrated on finalizing the improvements that users will be able to enjoy in MAAS 2.3 and preparing the for the first beta release. While MAAS 2.3.0 beta 1 will be announced separately, we wanted to bring you an update of the work the team has been doing over the past couple weeks.

MAAS 2.3 (current development release)

  • Hardware Testing Phase 2
    • Backend work to support the new UX changes for hardware testing. This includes websockets handlers, directives and triggers.
    • UI – Add ability to upload custom hardware tests scripts.
    • UI – Update the machine listing page to show hardware status. This shows status of hardware testing while pending, running, failed, degraded, timed out, etc.
    • UI – Implement new designs for Hardware Testing:
      • Add cards (new design) on node details pages that include metrics (if tests have been run) and hardware test information.
      • Add a new Hardware Test tab that better surfaces status of hardware tests per component
      • Add a more detailed log view of hardware test results.
      • Surface hardware test results per storage device on each of the block devices (on the machines details page).
      • Add ability to view all test results performed on each of the components overtime.
  • Switch Support
    • Add actions to switch listing page (still under a feature flag)
    • Fetch Wedge 100 switch metadata using the FRUID API endpoint on the BMC.

  • UI improvements
    • Add DHCP status column on the ‘Subnet’s tab.
    • Add architecture filters
    • Implement a new design for node details page:
      • Consolidate all of machine, devices, controllers, switches Summary tab into cards.
      • Add a new Settings tab, combined with the Power tab to allow editing different components of machines, devices, controllers, etc.
      • Consolidate commissioning output and installation logs in a “Log” tab.
    • Update VLAN and Space details page to no longer allow inline editing.
    • Update VLAN page to include the IP ranges tables.
    • Convert the Zones page into AngularJS (away from YUI).

MAAS 2.3.0 Alpha 3 release!

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.

Issues fixed in this release

  • #1702703    Cannot run maas-regiond without /bin/maas-rack
  • #1711414    [2.3, snap] Cannot delete a rack controller running from the snap

  • #1676992    [2.2] Zesty ISO install fails on region controller due to postgresql not running
  • #1703035    MAAS should warn on version skew between controllers
  • #1708512    [2.3, UI] DNS and Description Labels misaligned on subnet details page
  • #1711700    [2.x] MAAS should avoid updating DNS if nothing changed
  • #1712422    [2.3] MAAS does not report form errors on script upload
  • #1712423    [2.3] 500 error when clicking the ‘Upload’ button with no script selected.
  • #1684094    [2.2.0rc2, UI, Subnets] Make the contextual menu language consistent across MAAS

  • #1707850    [2.2] MAAS doesn’t report cloud-init failures post-deployment
  • #1711714    [2.3] cloud-init reporting not configured for deployed ubuntu core systems
  • #1681801    [2.2, UI] Device discovery – Tooltip misspelled
