Problems solved by technology

[0005] With the development of new functions, the MON command set is getting bigger and bigger. If there are very frequent command requests, the command set must be requested once every time the command is executed, which will consume a large network bandwidth.

Abstract

The invention discloses a method for executing CLI command of a distributed file system and a device thereof, and the method comprises the steps: the instantiation of a monclient process is performed in response to a to-be-executed command received by a CLI terminal, and the network connection between the monclient process and an MON is built; the monclient process searches whether the CLI terminal contains a local monitoring command set or not; in response to a local monitoring command set contained in the CLI terminal, the monclient process sends a version number of the local monitoring command set to the MON; and the MON checks whether the version number of the local monitoring command set is consistent with the version number of the server-side monitoring command set, and sends a corresponding ACK message to the monclient process based on a check result, and the monclient process processes the local monitoring command set after receiving the ACK message. According to the invention, the execution process of the CLI command is optimized, and the occupied network bandwidth is reduced.

Description

technical field [0001] The invention relates to the technical field of distributed file system monitoring, in particular to a method and device for executing CLI commands of a distributed file system. Background technique [0002] The distributed file system provides a CLI (command-line interface, command line interface) system for user and system interaction. Users enter commands on the CLI command line interface to query the status of the distributed file system or set some system parameters. [0003] CLI commands are executed by MON (MONitor, monitor). MON is the monitoring process of the distributed file system. An odd number (usually 3 or 5) MON services deployed on different server nodes form a distributed MON cluster. The MON cluster achieves consistency through the PAXOS algorithm and manages the state of the distributed file system. The MON cluster elects a primary MON through elections, and the rest are standby MONs. [0004] When the user enters a command thro...
