Abstract

The present application provides a data balancing method, device, and management device in a distributed storage system. The method includes: when receiving a data write request from a client, determining a target storage node from multiple storage nodes so that the client Write the target data corresponding to the data write request into the target storage node; based on the amount of stored data in each storage node, determine at least one backup storage node from the remaining storage nodes different from the target storage node among the multiple storage nodes; The identification information of the backup storage node is sent to the target storage node, so that the target storage node respectively writes the target data into at least one backup storage node. The data balance method, device and management equipment in the distributed storage system provided by the present application take into account the problem of data balance when data is written, which greatly reduces the situation of data imbalance.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data balancing method, device and management equipment in a distributed storage system. Background technique [0002] At present, after using the distributed storage system for data storage platform for a period of time, due to reasons such as hot data and hot applications, the data will be unbalanced among the servers, and the data imbalance will lead to IO bottlenecks. [0003] In the existing technology, in order to solve the problem of data imbalance, the operation and maintenance personnel need to regularly query the data status of each server in the service cluster. When the server has data imbalance, the operation and maintenance personnel will manually perform the operation of balancing the data. [0004] However, there are certain problems in the way that the operation and maintenance personnel manually perform data balancing: when the balance operation is started...
