mrconfig dg create raid0

The mrconfig dg create raid0 command creates a disk group striped for RAID 0. When the disk group is created MapR assigns one of the disks as the device path of the disk group. After you create a disk group you will be ready to create a storage pool on the disk group.

See mrconfig for instructions about running mrconfig commands.


/opt/mapr/server/mrconfig dg create raid0 [-d <stripeDepth>] <path>





host IP address; default


The MapR-FS port; default 5660


The stripe depth in 8K blocs; default 128 (1 MB)


The device path of each of the disks to add to the disk group; example /dev/sdc /dev/sdd /dev/sde


Create a disk group striped for RAID 0 with a stripe depth of 24 on a local node
