Adding Disks
You can add one or more available disks to MapR-FS using the disk add
command or
the MapR Control System. In both cases, MapR automatically takes care of formatting the
disks and creating storage pools.
NOTE: Disks must be added on CLDB nodes one node at a time when Warden and MapR services are running.
Complete the following steps to add disks using the MapR Control System:
- Add physical disks to the node or nodes according to the correct hardware procedure.
- In the Navigation pane, expand the Cluster group and click the Nodes view.
- Click the name of the node on which you wish to add disks.
- In the MapR-FS and Available Disks pane, select the checkboxes beside the disks you wish to add.
- Click Add Disks to MapR-FS to add the disks. Properly-sized storage pools are allocated automatically.
