Claim 17:
18. The method according to claim 1, wherein in response to receiving the request to allocate the storage space, acquiring the information of the logical unit space corresponding to the request, and allocating the idle hard disk in the storage pool for the logical unit space according to the total hard disk information comprises:
when receiving the request to allocate the storage space, creating the logical unit space, and notifying, by the cluster driver of the main controller, other cluster drivers of a message of the logical unit space;
finding an idle hard disk from the storage pool according to size of the logical unit space, wherein the physical information of the hard disks is updated when capacity of the hard disks changes, so that the cluster driver know which hard disks are idle according to the physical information of the hard disks; and
allocating the idle hard disk to the logical unit space according to sequence of the hard disks.
