Image forming apparatus which executes rebuild processes

A non-transitory computer-readable recording medium storing a controlling program for an image forming apparatus, wherein

• the image forming apparatus comprises:
• a first and a second fixed storage devices,
• a controller to execute rebuilding processes in which data being stored in the first fixed storage device is copied to the second fixed storage device, when the second fixed storage device failed is restored, and
• a CPU (Central Processing Unit) to access each of the first and the second fixed storage devices, wherein
• the controlling program causing a computer to execute the steps of:
• determine whether the rebuilding processes are being executed or not, when there arises the necessity for accessing from the CPU to at least of the first and the second fixed storage devices,
• acquire a priority of data which is an object for access by the CPU and a priority of data which is being processed under the rebuilding processes, when the rebuilding processes are being executed,
• determine whether the priority of data which is the object for access by the CPU is higher than the priority of data which is being processed under the rebuilding processes or not,
• stop the rebuilding processes, when the priority of data which is the object for access by the CPU is higher than the priority of data which is being processed under the rebuilding processes, and
• restart the rebuilding processes, when the access from the CPU to at least one of the fixed storage devices was finished.

A controller which communicates with a CPU (Central Processing Unit) which access each of the first and the second fixed storage devices, wherein the controller comprises:

• a rebuild processor to execute rebuilding processes in which data being stored in the first fixed storage device is copied to the second fixed storage device, when the second fixed storage device failed is restored,
• a determination unit to determine whether the rebuilding processes are being executed or not, when there arises the necessity for accessing from the CPU to at least of the first and the second fixed storage devices,
• a priority acquire unit to acquire a priority of data which is an object for access by the CPU and a priority of data which is being processed under the rebuilding processes, when the determination unit determined that the rebuilding processes are being executed,
• a priority determination unit to determine whether the priority of data which is the object for access by the CPU is higher than the priority of data which is being processed under the rebuilding processes or not,
• a stop unit to stop the rebuilding processes, when the priority determination unit determined that the priority of data which is the object for access by the CPU is higher than the priority of data which is being processed under the rebuilding processes, and
• a restart unit to restart the rebuilding processes, when the access from the CPU to at least one of the fixed storage devices was finished.
