Abstract

The invention discloses a NAS cluster cache processing method and system. The method includes: sending an instruction to modify a file or directory to a corresponding target NAS server through a target NAS client; judging whether there are other NAS clients in the same NAS cluster Access the same directory as the target NAS client; if so, modify and cache the metadata of the target file or directory through the target NAS server; notify the corresponding NAS client of the same directory as the target NAS client through the inter-process message mechanism The NAS server refreshes the metadata of the corresponding target file or directory in the local cache. By using the inter-process message mechanism to notify between different processes of the NAS service server for the NAS client, the timeliness and consistency of the cached data of different NAS servers are ensured, so as to realize the caching of data between various service processes effectiveness.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a NAS cluster cache processing method and system. Background technique [0002] With the development of information technology, in order to improve resource utilization efficiency and provide file sharing and data backup for different operating systems in the network, people usually use NAS network storage at present. [0003] Through NAS network storage, different users can simultaneously access various resources in the NAS network storage without affecting each other. However, in the storage system provided by the NAS protocol, the performance problem of the protocol layer has always been a difficult problem for developers. It is a common method to cache metadata and data of files or directories on the NAS server, but the effectiveness of the data cache is difficult to guarantee. [0004] Therefore, how to improve the performance of the NAS protocol and ensure the effectivene...
