Abstract:
1. A method performed by a data processing device, the method comprising: identifying a subset of physical disks within a node, the identified subset comprising at least one of the physical disks having at least one subdisk with free storage space, wherein the node comprises processing units and the physical disks arranged to form at least one group; assigning a priority value to the identified subset of the physical disks; sorting the identified subset of the physical disks based on the assigned priority value; and selecting subdisks from the sorted subset of the physical disks to form a logical disk; wherein the assigning comprises: assigning a priority value for sorting the identified subset of the physical disks; assigning a priority value for sorting the processing units within a given group; and assigning a priority value for sorting the at least one group within the node.
