+  categoryDescription: |
+    This experiment causes disk stress on the application pod. The experiment aims to verify the resiliency of applications that share this disk resource for ephemeral or persistent storage purposes.    
+    - Consumes the disk available by executing filesystem IO stress as available memory or by providing the value in GB
+    - The application pod should be healthy once chaos is stopped. Expectation is that service-requests should be served despite chaos.
