摘要：
In a multinode storage system, a virtual disk associated with a storage device to be connected is created, and a slice of a connected storage device is allocated to one segment of the virtual disk. Next, one slice of data in the storage device to be connected is copied to the connected storage device. The rest of data in the storage device to be connected is divided into slices, which are allocated to segments of the virtual disk. Then, metadata of the rest of the slices is written into a management information area in which copying of the data therefrom has been completed.
