摘要： A computer-readable medium storing a data management program makes a computer manage data redundantly stored in storage devices having storage areas split into slices for data management. The data management program realizes the following functions in the computer. A first function receives irregularity information indicating that each of one or more of the storage devices may be possibly faulty, and stores the irregularity information in a storage; and a second function determines, by reference to the irregularity information, whether or not a first storage device containing a slice to be accessed is possibly faulty, on receipt of access information indicating occurrence of a request to access the slice. When yes is determined, the second function instructs an external device to recover data stored in the slice, where the external device controls a second storage device storing redundant data identical to the data stored in the slice.

摘要： A management device obtains, from the plurality of storage nodes, information of accesses which are made to the actual storage areas included in the storage nodes, generating load information of the actual storage areas based on the access information, and storing the generated load information in a load information storage unit. The device changes, based on the load information stored in the load information storage unit, the assignment relations of the actual storage areas with respect to the virtual storage areas such that loads of the storage nodes are leveled. The device instructs the plurality of storage nodes to move the data in the actual storage areas depending on change in the assignment of the actual storage areas to the virtual storage areas.

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 the 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.
