Detailed Description
Round Robin is an very simple distribution: The disks are arranged in an 0..(numDisks-1) interval and each extend is placed beginning at disk ((position + virtualVolumeId) * copies) % numDisks at the following copies disks. This algorithm is mostly for testing and is absolutly not adaptive. :-)
