QuestionQ45

Configuring Data Services

An administrator runs a TreeDelete job to remove a large directory. After the job begins, users observe a cluster performance problem. Which recommended action will resolve the job-related performance issue?

  • A Modify the running job to use a high impact policy to reduce the amount of time users are impacted. Schedule the job after business hours in the future.
  • B Let the job continue to run at the current impact level and schedule future jobs for after business hours so they do not impact users.
  • C Modify the running job to use an OFF_HOURS policy that runs at low impact during business hours and medium impact after business hours.
  • D Pause the running job and resume after business hours using a high impact policy so that it does not impact users.
Explanation

OneFS Job Engine impact policies control the cluster resources a running job may consume. A HIGH-impact job can use substantially more resources, so it should not run while client users are experiencing performance degradation. Pausing the job removes its current workload impact; resuming it after business hours at HIGH impact allows faster completion during a period of lower client activity. The default OFF_HOURS policy pauses during business hours and runs at low impact outside them, not at medium impact after business hours.
