A storage hard disk detection and early warning method and system

Abstract

The invention discloses a storage hard disk detection and early warning method and system, which comprises the following steps: collecting physical hard disk state information; obtaining the detection type of the hard disk state information; obtaining the detection result of the hard disk state information according to whether the hard disk damage information is wrong; Whether the write rate information is higher than the preset read / write rate threshold obtains the detection result of the hard disk status information; obtains the predicted life of the hard disk based on the Bayesian prediction algorithm; obtains the detection result of the hard disk status information according to whether the predicted life of the hard disk is higher than the preset life threshold. The present invention obtains the hard disk state information detection result according to the hard disk state information detection type after obtaining the hard disk state information detection type, and monitors the running state of the physical hard disk on the server through multiple types of hard disk state information detection results, which can be very good To ensure the stable and normal operation of the distributed storage system, and reduce the impact on the user's business system due to physical hard disk problems.

Description

technical field [0001] The invention relates to the technical field of storage hard disk management, in particular to a storage hard disk detection and early warning method and system. Background technique [0002] With the advent of the big data information age, a large amount of data is generated every day for storage. Inherited centralized SAN storage can no longer meet the requirements of users, resulting in a distributed storage with unlimited capacity, continuous increase of nodes, and interaction through the network. The arrival of distributed storage solves the bottleneck of capacity and performance, but also brings the bottleneck of the barrel principle. In a distributed storage system, because the client will send the requested IO to all the physical hard disks of the node, if a physical hard disk is bad or slow, this will affect the client whose IO falls to this hard disk The access to the terminal brings a very bad experience to customers. [0003] Therefore, ...

AI Technical Summary

Problems solved by technology

For a distributed storage system based on network communication, the data reconstruction process puts pressure on the network switch, and the physical hard disk that is undergoing data reconstruction will also be the hard disk accessed by the client's business, so the impact of the double pressure is easy to affect the customer's business make an impact

[0004] Therefore, how to know which physical hard disk is about to be damaged at the first time, and then actively intervene to avoid affecting the use of the customer's business system due to slow disk or bad disk, has become a technical problem to be solved urgently by those skilled in the art
