Answer

  • Jobs are asynchronous tasks and typically long-running volume operations, such as copying, moving, or mirroring data.
  • Jobs are placed in a job queue and are run when resources are available.
  • Some jobs want to start and run to completion without interruption.
  • Other jobs initiate some external operation and wait for that operation to complete.
  • To avoid wasting a thread, in this latter case doing nothing but waiting, the job can relinquish the thread but tell the Job Manager that there is more work to do.
  • The Job Manager periodically reschedules the job to allow it to check on completion of this external operation.
  • Some of the default jobs that we expect to see on any NetApp appliance:
::> job show -fields id,name,affinity
id vserver          name                                       affinity

Additional Information

  • The general rule of thumb is that cluster or node affiliated jobs must not be touched unless instructed by NetApp Support.
  • If an issue is suspected with any of those jobs, please contact NetApp Technical Support and reference this article for further assistance.
  • Following EMS events can be monitored for job-related errors (for any or a particular job):
    • mgmtgwd.jobmgr.fetcherr
    • mgmtgwd.jobmgr.init.err
    • mgmtgwd.jobmgr.jobcomplete.failure
    • mgmtgwd.jobmgr.jobrestart
    • mgmtgwd.jobmgr.nofork
    • mgmtgwd.jobmgr.private.jobcomplete.failure
