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.
