The ReadyNAS will create a single non-
redundant volume. You will need to add
disks to provide redundancy.

We do not recommend expanding across
multiple chassis.
Note: ReadyNAS does not create volume
automatically on the expansion chassis. You
need to go to the Volumes tab and create
your desired volume on the expansion
chassis.
11.2. The Volume Wizard
Due to the complexity of managing volumes for ReadyNAS devices with a high number of drive bays, we’ve added a Volume
Wizard in ReadyNAS OS 6.7. The Volume Wizard provides users with a step-by-step guide to create and modify volumes with
performance characteristics that match their application.
