This application discloses a method, apparatus, and medium for handling abnormal RAID member disks, relating to the field of disk array storage. In order to reduce the experimentation of hot spare disks, this application provides a method to reserve a portion of storage space on the RAID member disks to store data sent by the host to the abnormal RAID member disks in the event of an abnormal RAID member disk. During the process of repairing the abnormal RAID member disks, the I / O commands received by the RAID card are directly cached in the hard drives of other normal member disks. After the RAID card successfully repairs the abnormal member disks, the RAID card can restore the data stored in the reserved storage space to the member disks that were abnormal before the RAID, avoiding data inconsistency problems caused by the member disks being unable to receive I / O commands. If the member disks can be successfully repaired, there is no need to start the hot spare disk.

The application provides a redundant array of independent disks (RAID) reconstruction method and device. When a fault disk is reconstructed, P target hot spare disks are selected to reconstruct a specified fault disk in the RAID. A logical disk for reconstructing the fault disk is created and divided into P subspaces. The space of the fault disk is divided into P subspaces. According to the corresponding relationship between the subspaces of the fault disk and the logical disk and the corresponding relationship between the subspaces of the logical disk and the mapping spaces of the target hot spare disks, the fault disk is reconstructed into each target hot spare disk in parallel. It can be seen that the technical solution provided by the embodiment does not reconstruct the fault disk into one selected hot spare disk according to the form that one fault disk corresponds to one hot spare disk, but selects multiple target hot spare disks at the same time and reconstructs the fault disk into the multiple selected target hot spare disks in parallel, so as to shorten the fault disk reconstruction time, improve the reconstruction efficiency of the fault disk in the RAID, and improve the reliability of the data in the RAID.
