Abstract
Embodiments of the present disclosure provide a method of managing a redundant array of independent disks (RAID) system and an electronic device. The method includes configuring a plurality of disks in the RAID system as a raw mirror for storing configuration data of the RAID system; storing metadata for the raw mirror in the plurality of disks, the metadata stored in each of the plurality disks including an identifier identifying that the disk belongs to the raw mirror and a sequence number identifying a writing operation for a block storing the metadata in the disk; and controlling reading and writing of the raw mirror based on the metadata.
