Determining if a Volume is Enabled for Tiering

You can determine if a volume is enabled for tiering and if rules, schedules, and/or settings for recalled data are associated with the volume using the MapR Control System and the CLI.

Determining if a Volume is Enabled for Tiering Using the MapR Control System

Log in to MCS and click Data > Volumes.
In the list of volumes displayed in the Volumes pane, the Data Tiering column contains the value Enabled for a volume if the volume is enabled for tiering. If you do not see the column, you can see the column by selecting the columns to display in MCS.

Determining if a Volume is Enabled for Tiering Using the CLI

Run one of the following commands to determine if a volume is enabled for tiering:
  • maprcli volume list -json
  • maprcli volume info -name <volName> -json
The output, if the volume is tiering-enabled (and has associated settings), should look similar to the following:
