Parameters

Parameter

Description

cluster

The cluster on which to run the command.

dumpfile

The name of the dump file (ignored if -o is used).

e

The name of the state file to create for the end point of the dump.

name

A volume name.

o

This option dumps the volume to stdout instead of to a file.

s

The start point for an incremental dump.

Note: In a secure cluster, you must use the MapR user ID. Using root or any other user ID results in the system hanging.

CLI
maprcli volume create -e statefile1 -dumpfile fulldump1 -name volume -n
