Problems solved by technology

However, in a storage system such as ICFS (Inspur Cluster File System, Distributed File System) system, a storage node supports 12 to 54 disks, making its OSD failure rate much higher than other systems
According to the data redundancy rules provided by the ICFS system, disk failures of storage nodes are allowed, but it must be ensured that the cluster can be used normally and the data is not lost. However, at present, the OSD fault handling in the ICFS system requires developers to locate on-site, which takes a long time to reduce. performance of the cluster

Abstract

The invention discloses an OSD fault location method and system based on an ICFS system. The method comprises the steps of classifying faults of OSD in the ICFS system in advance, and classifying fault determination manners corresponding to the faults; obtaining fault determination information of the ICFS system, wherein the fault determination information includes OSD information of each OSD in the ICFS system and / or data redundancy rules of the ICFS system; determining whether or not there are faults of the OSD according to the fault determination information combined with the preset fault determination manners and the classification of the faults. The method classifies the faults and fault determination manners of the OSD in advance, which serves as a basis for determining subsequent OSD fault location, so that convenience is provided for subsequently determining whether or not there are the faults of the OSD in combination with the fault determination information of the ICFS system, a location direction is provided for a possible fault, and the method shortens the fault location time, improves the fault handling efficiency, and improves the performance of a cluster.

Description

technical field [0001] The invention relates to the technical field of distributed systems, in particular to an ICFS system-based OSD fault location method and system. Background technique [0002] At present, for mass storage products, users can define data redundancy rules (such as copy or erasure correction), and specify the physical storage location of data through the CRUSH algorithm to complete the separation of fault domains. However, in a storage system such as ICFS (Inspur Cluster File System, Distributed File System) system, a storage node supports 12 to 54 disks, which makes the OSD failure rate much higher than other systems. According to the data redundancy rules provided by the ICFS system, disk failures of storage nodes are allowed, but it must be ensured that the cluster can be used normally and the data is not lost. However, at present, OSD fault handling in the ICFS system requires developers to locate on-site, which takes a long time to reduce. performanc...
