mrconfig

The mrconfig commands let you create, remove, and manage storage pools, disk groups, and disks; and provide information about containers.

NOTE: The mrconfig commands provide direct control and access to MapR-FS at a low level. If you are not careful, or do not know what you are doing, you can irrevocably destroy valuable data.
