Starting a Mirror
About this task
Procedure
- In the Navigation pane, expand the MapR-FS group and click the Volumes view.
- Select the checkbox beside the name of each volume you wish to mirror.
- Click the Start Mirroring button.
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.
