Using the Enable MapR DARE Option

You use the Enable MapR DARE option to enable data-at-rest encryption for MapR volumes.

This option appears on the Version & Services page of the web-based MapR Installer when the Enable MapR Secure Cluster option is selected. The Enable MapR DARE option is deselected by default.

For more information about data-at-rest encryption, see Encryption in MapR.

Considerations for Enabling MapR DARE Using the MapR Installer

Before using the Enable MapR DARE option, review these considerations:
Important: Once enabled, the Enable MapR DARE option cannot be disabled, since disk encryption cannot be turned off without reformatting the disks.
  • The Enable MapR DARE option can only be used during the initial installation of a MapR cluster or during an incremental install.
  • You cannot select the Enable MapR DARE option when:
    • The Enable MapR Secure Cluster option is deselected.
    • You perform an upgrade operation using the MapR Installer. Security changes are not allowed during an upgrade using the MapR Installer.
  • If you select the Enable MapR DARE option, you can no longer deselect the Enable MapR Secure Cluster option during an Incremental Install operation.
