Disk monitoring method for cloud storage system

The invention provides a disk monitoring method for a cloud storage system. The disk monitoring method for the cloud storage system includes that each service node of a plurality of service nodes sends disk state information to a management node at a predetermined period; and a disk information log sheet corresponding to disks of the plurality of service nodes is established by the management node, a disk state of a corresponding disk in the disk information log sheet is updated according to received disk state information by the management node. According to the disk monitoring method for the cloud storage system, the disk state information is sent to the management node at the predetermined period through the service nodes in the cloud storage system run process, and therefore the disk information log sheet can be timely updated by the management node, the disk state is monitored in real time with the method, and data security in the cloud storage system is guaranteed.
