Problems solved by technology

[0003] The smallest unit of data redistribution is an object. At present, data redistribution uses a fixed number of processes to perform concurrent redistribution operations. However, in this case, when the pressure on the OSD front-end receiving the redistribution request is high, the data redistribution process and Normal business preempts system resources, causing front-end normal business to slow down or even fail; when the pressure on the OSD front-end receiving reallocation requests is low, the process of data reallocation cannot make full use of system idle resources to improve the efficiency of data reallocation; It can be seen that the current way of fixing the number of concurrency is poor in adaptive effect

Abstract

The invention discloses a distributed system data redistribution method and device. A distributed system comprises multiple object storage devices, wherein each object storage device comprises multiple objects. The method comprises the steps that each object storage device periodically collects load information thereof and transmits the load information to a main object storage device; the main object storage device dynamically adjusts a concurrent process number of data redistribution according to the received load information of all the object storage devices and a first preset strategy; the main object storage device sends a data redistribution request to the corresponding objects according to the concurrent process number obtained after adjustment and performs data redistribution operation; and the data redistribution request comprises a reading request and a writing request. Through the distributed system data redistribution method and device, the concurrent process number of data redistribution can be adjusted according to front-end business conditions of the object storage devices, and the effect of adaptive adjustment is good.

Description

technical field [0001] The invention relates to the technical field of distributed systems, in particular to a distributed system data redistribution method and a device thereof. Background technique [0002] The distributed system includes multiple object storage devices OSD, and each object storage device includes multiple objects. When the distributed system dynamically expands or shrinks, that is, when the number of OSDs contained in the distributed system changes, it is necessary to change the The data in the previous OSD is read, and redistributed and written to the changed OSD, wherein these read requests and write requests are sent under the control of the main object storage device in the distributed system. [0003] The smallest unit of data redistribution is an object. At present, data redistribution uses a fixed number of processes to perform concurrent redistribution operations. However, in this case, when the pressure on the OSD front-end receiving the redistri...
