For any machine which has undergone testing, the Tests log screen – under the “Tests” tab – shows a list of tests that have been run for that machine, along with a timestamp and result. You can view the detailed logs for each test script from this tab.
By default, every MAAS machine is tested with the smartctl-validate script, which is a script prepared by Canonical using the smartmontools↗ kit. This is a disk integrity test. Typical output includes the following:
INFO: Verifying SMART support for the following drive: /dev/sda
INFO: Running command: sudo -n smartctl --all /dev/sda
INFO: SMART support is available; continuing...
INFO: Verifying SMART data on /dev/sda
INFO: Running command: sudo -n smartctl --xall /dev/sda
SUCCESS: SMART validation has PASSED for: /dev/sda
