Problems solved by technology

The main problem faced by the joint file system is that the performance of file update and writing is relatively low, and the file writing is not redundant to protect the data. At the same time, there is no effective discovery and isolation mechanism for directory failures in the hierarchy.

Abstract

The invention discloses a method and device for finding and isolating a joint file system fault. An error counter is set up for each hierarchical directory; whenever a file IO failure occurs, the error counter of the hierarchical directory is incremented by one bit; a timer is set reset the error counters of all hierarchical directories regularly; when the error counters are self-incrementing, if the number of errors in the error counters exceeds the specified threshold, the hierarchical directory will be marked as an error, and the error isolation program will be executed. The aggregation feature of the joint file system is further utilized, the fault tolerance of the joint file system is improved, and the IO of the joint file can still be guaranteed to run normally even if some layers of the joint file system fail.

Description

technical field [0001] The present disclosure relates to the field of computers, in particular to a method and device for discovering and isolating faults in a joint file system. Background technique [0002] The joint file system is a virtual file system. It does not have a real entity. Instead, it aggregates the file systems of multiple entities to form a hierarchy and constitutes a virtual file system. Read and write will be mapped to the hierarchically aggregated entity file system. The Union File System (UnionFS) is a lightweight, high-performance layered file system that supports submitting the modification information in the file system as a single submission and superimposing them layer by layer. At the same time, different directories can be mounted to the same virtual file Under the system, what the application sees is the final result of the mount. [0003] The joint file system is a common file system in the linux system. The core structure of this file system ...
