Creating a Mirror from the MCS

To create a mirror from the MCS, follow these steps:
  1. Under the MapR-FS group in the navigation pane, click on Volumes, then click on the New Volume tab. The New Volume dialog box displays.
  2. Complete the New Volume dialog box.
    1. Choose Remote Mirror Volume.
    2. Give the volume a name (the mirror is named volA in this example).
    3. Provide the name of the source volume and the cluster where it resides (the source volume is volA and the cluster is Cluster1 in this example).
    4. Supply the mount path (/A in this example).
    5. Select a snapshot schedule (specifies when to take snapshots of the volume). The default choices are None, Critical data, Important data, and Normal data.
      Warning: If the mirror volume is later promoted to a read-write volume, the snapshot schedule will apply to that volume and the mirror schedule will be disabled.
    6. Select a mirror schedule (specifies the mirroring interval of the volume). The default choices are None, Critical data, Important data, and Normal data. If you choose None, start the mirror manually by selecting Start Mirroring from the Volume Actions tab.
