Embodiment Construction

[0042] A disk failure prediction method of the present application is suitable for performing failure prediction on disks in storage nodes in a storage system. like figure 1 As shown in , it shows a schematic diagram of the composition architecture of a storage system of the present application, consisting of figure 1 It can be seen that the storage system includes a plurality of storage nodes 101 and at least one monitoring server 102, wherein the monitoring server can also be regarded as a storage node with data collection and data processing functions.

[0043] Wherein, the storage node 101 has a disk for storing data.

[0044] In the embodiment of the present application, the storage node can obtain the operating status information of the disk, such as the operating time of the disk, load status, health status (such as whether there are bad blocks and the number of bad blocks, etc.), and the obtained The running status information of the disk is reported to the monitorin...

Abstract

The invention provides a disk fault monitoring method and device and a storage system. The method is applied to a monitoring server in the storage system. The storage system comprises a plurality of storage nodes, and the storage nodes are provided with disks. The method comprises the steps that current running state information of the disks in the storage nodes is acquired; based on the current running state information of the disks, by using a state transition model obtained through training in advance, fault generation conditions of the disks after the current time are predicted, fault prediction results are obtained, and the state transition model is obtained based on training of historical running state information of the disks of the storage nodes and the historical actual fault generation conditions before the current time; the fault prediction results of the disks are sent to a user terminal. According to the technical scheme, the method helps to deal with disk faults in time, and the situation is avoided that the storage system is unstable due to the disk faults.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular to a disk failure monitoring method, device and storage system. Background technique [0002] In order to improve the reliability of data storage, the storage system needs to store data redundantly. Therefore, the storage system needs to deploy a large number of disks to meet the storage capacity requirements. As the number of disks in a storage system increases, so does the number of disk failures. [0003] In order to avoid abnormal data reading of the storage system due to a disk failure, after a disk failure occurs, the administrator of the storage system needs to use a pre-prepared disk to replace the failed disk. However, due to the uncertainty of the faulty disk, how to ensure the timely processing of the faulty disk, replace the fault in time, and reduce the unstable situation of the storage system caused by the disk failure is a technology urgently neede...
