mrconfig disk init
The mrconfig disk init
command initializes a disk and
formats it for the MapR filesystem.
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:
- The Add Disk(s) to MapR-FS button in the MapR Control System, or
- The
maprcli disk add
command.
