mrconfig disk init

The mrconfig disk init command initializes a disk and formats it for the MapR filesystem.

Note:

Warning: Initializing a Disk Causes Data Loss

Initializing a disk destroys the data on the disk, so be sure that all data on a disk is backed up and replicated before initializing the disk.

After executing the mrconfig disk init command, add the disk to the node with the mrconfig disk load command.

See mrconfig for instructions about running mrconfig commands. Tip:

To initialize, format and load one or more disks in one step, use:

Syntax

    <path>

Parameters

Parameter

Description

-F
