Abstract

The invention discloses a file processing method and device based on erasure codes and computer equipment, and the method is applied to a FastDFS system, and comprises the steps: obtaining a cold filein a hot data set of a storage server; partitioning the cold file according to a preset partitioning rule to obtain file blocks corresponding to the cold file; encoding the file block according to anerasure code technology to obtain a check block corresponding to the file block; storing the file block and the check block into a cold data set of the storage server; and if a downloading request for downloading the cold file is received, obtaining the cold file from the cold data set according to the downloading request. Based on the hierarchical storage technology, the files stored in the FastDFS system are optimized to improve the storage utilization rate of the disk, the storage cost is reduced, and the operation and maintenance efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of distributed storage, and in particular relates to an erasure code-based file processing method, device and computer equipment. Background technique [0002] FastDFS is an open source lightweight distributed file storage system developed in C language, which consists of Tracker Server, Storage Server and Client. Among them, the storage server is divided into several groups for actually storing data, and the storage in the group backs up each other to ensure high availability of data. Since the N storages in the same group have the same data, it can tolerate N-1 storage failures, but its storage utilization rate is 1 / N. Distributed file storage systems such as Hdfs and Ceph use erasure code technology to encode n original data blocks to generate m check blocks, and store these n+m data blocks in the system. While the block is wrong, the system is guaranteed to be available, which reduces the storage effic...
