A library, GUI and sample cli script for managing Data Robotics storage units on Linux. (http://www.drobo.com)
There is a library, Drobo.py, which implements the ioctl interface defined in the published specs and code samples.
Tried to use with a Drobo FS but this software can not find any devices. Software appears to be only suitable for a drobo that is attached via USB connection and NOT via ethernet.
Very useful piece of software if your environment doesn't provide the possibility to run the vendors windows software. The supported features might be currently not on the same level of the windows pendant but it's getting there sooner or later.
