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.

Embodiment Construction

[0032] The concept, specific structure and technical effects of the present disclosure will be clearly and completely described below in conjunction with the embodiments and drawings, so as to fully understand the purpose, scheme and effect of the present disclosure. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0033] Such as figure 1 Shown is a flow chart of a joint file system fault discovery and isolation method according to the present disclosure, combined below figure 1 A joint file system fault discovery and isolation method according to an embodiment of the present disclosure will be described.

[0034] The disclosure proposes a joint file system fault discovery and isolation method, which specifically includes the following steps:

[0035] Step 1, monitor the file IO errors that occur in the hierarchical directories in the joint file system and co...

Abstract

The invention discloses a joint file system fault detection and isolation method and a device thereof. An error counter is set for each hierarchical directory. Each time a file IO failure occurs, theerror counter of the hierarchy directory is incremented by one bit; setting up a timer to periodically clear the error counters of all hierarchical directories; when the error counter is incremented,if the number of errors found in the error counter exceeds the specified threshold, then, the hierarchical directory is identified as error, and an error isolation program is executed, which further exerts the aggregation characteristic of the federated file system, improves the fault tolerance of the federated file system, and ensures that the IO of the federated file can still run normally in the event of failure of some hierarchical levels in the federated file system.

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 ...
