Terminating a Running Volume-Level Tiering Job

Describes how to terminate a volume-level tiering job using either the Control System or the CLI.

About this task

You can terminate an ongoing offload or recall of a volume using the Control System or the CLI. Terminating a running:

  • Offload operation does not prevent future offloads; if a schedule is associated with the volume, data that is still on the cluster is automatically offloaded based on the rules as per schedule. You can also manually offload data again at any time by running the volume offload command.
  • Recall operation does not prevent future recalls; you can run the recall command again to recall the remaining data on the tier. Based on the expiry time set on the volume (associated with the recalled data), recalled data is offloaded if there are changes or purged if there are no changes. See Recalling a Volume to file system for more information.

You can check the status of an abort operation using the volume tierjobstatus command.

NOTE
If you terminate a job that CLDB was retrying after a prior failed attempt (FailureRetriable job), CLDB will stop trying to run the job again. For more information on FailureRetriable job, see Retrying Failed Operation.

For information on terminating a file-level job, see Terminating a Running File-Level Tiering Job and Running Tiering Commands when maprcli and hadoop Commands are not Available.
