Abstract
Disclosed is a computer program stored in a computer readable medium according to an exemplary embodiment of the present disclosure. The computer program performs the following method for moving an extent when being executed by one or more processors of a computing device and the method may include: deciding, by the processor, movement of an extent stored in a first disk in a disk space in which the disk space includes at least two disks; determining, by the processor, whether there is writing work for the extent based on extent mapping information for the extent; changing, by the processor, a state of the extent to read-only in the extent mapping information when there is no writing work for the extent; moving, by the processor, the extent positioned in the first disk to a second disk; and updating, by the processor, the extent mapping information based on completion of the disk movement of the extent.
