Embodiment approach

[0022] According to an embodiment of the present invention, when it is found that the waiting time of a certain I / O operation of a certain hard disk exceeds a preset threshold, corresponding fault-tolerant processing is performed for transient errors. Specifically, when the waiting time of the read operation exceeds the preset threshold, in order to avoid the stall and blockage of the streaming media service related to the read operation of this hard disk, the streaming media service application is notified to send all the related streaming media services that can read the hard disk All services are switched to other nodes that store related content. If the read operation fails directly without timeout, the streaming media service application is notified, and only the streaming media related to this read operation is switched to other nodes. When the waiting time of the write operation exceeds the preset threshold, for the streaming media service operation related to the write...

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 ...
