Problems solved by technology

However, since the business cannot be interrupted during the execution of the copy management command, it means that the business is always running during the reconstruction process. If the good copy selected at this time happens to be the copy being accessed by the virtual machine, the disk corresponding to the copy will change. Random IO (virtual machine read and rebuild read at the same time), reduces the efficiency of copy management, and also affects the normal execution of the business

Abstract

The invention discloses a copy management method, and the method comprises the steps: determining a data copy in a file system, and setting the currently accessed data copy as a reading source copy; setting the data copies except the reading source copy as target data copies; if a copy management instruction is received, copying the target data copy to a host corresponding to the copy management instruction, wherein the copy management instruction comprises a copy reconstruction instruction, a copy synchronization instruction or a load balancing instruction. According to the invention, the replica management efficiency can be improved, and the influence of replica management operation on execution of normal services is reduced. The invention further discloses a copy management device, a storage medium and electronic equipment, which have the above beneficial effects.

Description

Technical field [0001] This application relates to the field of data storage technology, and in particular to a copy management method, device, electronic equipment and storage medium. Background technique [0002] Distributed storage is to store data in multiple independent devices. The distributed network storage system adopts an expandable system structure, uses multiple storage servers to share the storage load, and uses location servers to locate storage information. It not only improves the reliability, availability, and access efficiency of the system, but is also easy to expand. [0003] In related technologies, if the distributed file system receives a copy management instruction (such as a copy reconstruction instruction, a copy synchronization instruction or a load balancing instruction), it needs to determine the target copy corresponding to the copy management instruction, and then complete the data from another good copy Copy to the newly created copy, and the recons...
