Abstract

The invention discloses a file positioning and storing method and device for a trunking system. The method comprises the steps of receiving an object file positioning instruction sent by a client terminal, wherein the object file positioning instruction contains the path information of an object file to be positioned; calculating the characteristic value of the object file to be positioned according to the path information; determining a value interval mapped by a memory address where the object file to be positioned is located according to the characteristic value; determining a first cluster node where the object file to be positioned is located according to the value interval mapped by the memory address; judging whether the first cluster node can conduct normal communication; determining that the object file to be positioned is located on the first cluster node if so. In this way, the problem of the prior art that cluster positioning can not be achieved when a master server breaks down is solved, the usability of the trunking system is improved, and then the technical effect of positioning a file accurately is realized.

Description

technical field [0001] The present invention relates to the field of cluster system file positioning, in particular to a cluster system file positioning and storage method and device. Background technique [0002] At present, the common cluster file index positioning method is realized by arranging the main data server in the cluster. Taking GFS (Global File System, GFS for short) as an example to illustrate: the GFS file system consists of the client, the main server and multiple It is composed of two data block servers, the main server plays the role of metadata server, and the index location information of files is saved on the main server. When locating a file, the client first sends a request to the main server, obtains the file information and the location of the data block server where the file is located, and then sends a request to the data block server to access the file data. The disadvantage of this method is that the file index depends on the master server. Whe...
