Starting a Mirror

When a mirror starts, all the data in the source volume is copied into the mirror volume. Starting a mirror volume requires that the mirror volume exist and be associated with a source. After you start a mirror, synchronize it with the source volume regularly to keep the mirror current. You can start a mirror using the volume mirror start command, or use the following procedure to start mirroring using the MapR Control System.
  1. In the Navigation pane, expand the MapR-FS group and click the Volumes view.
  2. Select the checkbox beside the name of each volume you wish to mirror.
  3. Click the Start Mirroring button.
