Creating custom preflight check

Create a custom preflight check to detect and fix specified configuration settings on DataStax Enterprise nodes.


  1. Create a new Python file in /checks:

    cd /checks
  2. Add the new test to the all section of /checks/

    __all__ = ['my_test', 'disk', 'blockdev', ...]
  3. Add your test to the preflight_check script.

  4. Run the preflight check script with the new test:

    sudo ./preflight_check [ options ]
