Hard disc error detection and fault-tolerant method in stream media uses

Abstract

The utility model discloses a hard disk fault detection and fault tolerant method based on streaming media service application, comprising: monitoring each I / O operation based on streaming media service application; counting the monitored result of a plurality of I / O operations in a certain duration; confirming whether hard disk faults of hard disk damage, mistaken hard disk stored content, bad hard disk block and hard disk instantaneous fault are appeared in hard disk based on the statistics of the monitored result of each I / O operation or a plurality of I / O operations; and conducting corresponding fault tolerant treatment combining streaming media service application. The method can rapidly and accurately detect the problems that seriously influence streaming media service application but are not easy to be found by traditional hard disk detection techniques such as S.M.A.R.T. The method of the utility model can accurately and rapidly find various faults of hard disk, and take corresponding fault tolerant measures, avoids or reduces the influence on streaming media service systems, thus improve the reliability and stability of the system.

Description

technical field [0001] The invention relates to the storage technology field of streaming media and IPTV (Internet Television), in particular to a hard disk error detection and fault tolerance method in the storage technology field of streaming media and IPTV. Background technique [0002] In high-bit rate streaming media applications, due to real-time reasons, there are high requirements on the performance, stability and reliability of the storage system. As a storage medium, hard disks often have problems such as transient errors, bad blocks, performance degradation, and content errors in the high-pressure and uninterrupted business model of streaming media services, which seriously affect streaming media services. [0003] The transient error of the hard disk refers to the fact that due to the influence of the surrounding environment or the hard disk itself, the hard disk has been waiting for a read or write I / O operation for a short period of time, such as a few seconds ...
