If you wish, you can tell MAAS to test machine hardware using well-known Linux utilities. MAAS can test machines that have a status of Ready, Broken, or Deployed. You can include testing as part of the commissioning process. When you choose the ‘Commission’ action, MAAS will display the dialog described below. Be aware, though, that if the hardware tests fail, the machine will become unavailable for Deployment.
[note] The majority of testing scripts only work with machines that are backed by physical hardware (e.g. they may be incompatible with VM-based machines). [/note]
To launch a test, select the target machine from the ‘Machines’ page and use the ‘Take action’ drop-down menu to select ‘Test hardware’. When ready, hit the ‘Test machine’ button. Here, a test is applied to a deployed machine:
There is the option of not powering off the machine and to allow SSH access.
A default test will be selected (
smartctl-validate, a hard drive test) but you can choose others by clicking the ‘Select scripts’ label. Doing so will reveal the following choices:
The following hardware testing scripts can be selected from the web UI:
|smartctl-short||storage||Run the short SMART self-test and validate SMART health on all drives in parallel|
|smartctl-long||storage||Run the long SMART self-test and validate SMART health on all drives in parallel|
|smartctl-conveyance||storage||Run the conveyance SMART self-test and validate SMART health on all drives in parallel|
|memtester||memory||Run memtester against all available userspace memory.|
|internet-connectivity||network, internet, node||Check if the system has access to the internet.|
|stress-ng-cpu-long||cpu||Run stress-ng memory tests for 12 hours.|
|stress-ng-cpu-short||cpu||Run stress-ng memory tests for 5 minutes.|
|stress-ng-memory-long||memory||Run stress-ng memory tests for 12 hours.|
|stress-ng-memory-short||memory||Run stress-ng memory tests for 5 minutes.|
|ntp||network, ntp, node||Run ntp clock set to verify NTP connectivity.|
|badblocks||storage||Run badblocks on disk in read-only mode.|
|badblocks-destructive||destructive, storage||Run badblocks on a disk in read/write destructive mode.|
|7z||cpu||Run 7zip CPU benchmarking.|
|fio||storage, destructive||Run Fio benchmarking against selected storage devices.|
After either commissioning, testing, or installation has started, MAAS reports in real-time which script is running.
You can access the verbatim output from any test by selecting a machine, selecting the ‘Hardware tests’ page and clicking on the ‘Log view’ link in the ‘Results’ column for the specific test.
See Commissioning and Hardware Testing Scripts for more details on how these scripts work and how you can write your own.
