Adding Volumes
Referring to the volume plan created in Planning the Cluster, use
the MapR Control System or
the maprcli
command to create and mount
distinct volumes to allow more granularity in specifying policy for
subsets of data.
NOTE:
If you do not set up volumes, and instead store all data in the
single volume mounted at
/
, it creates problems in
administering data policy later as data size grows.
