Simplified configuration file copying method, device and equipment and readable storage medium

Abstract

The invention discloses a simplified configuration file copying method, device and equipment and a readable storage medium. The method comprises the steps of: enabling a target host to send a copyingrequest of a target file to a source host and receive file information, returned by the source host, of the target file; if the target file is the simplified configuration file, creating a virtual storage area which has the same size as the target file and does not occupy the disk space according to the file information; sending the acquisition request of the target data segment to the source host one by one, receiving the target data segment returned by the source host, and storing the target data segment to a disk address corresponding to the virtual storage area in a simplified configuration manner, so as to copy the target file from the source host to the target host, wherein the target data segment is any one of all data segments included in the target file. According to the method,after the simplified configuration file is copied across hosts, the advantages of simplified configuration are reserved. The simplified configuration file copying device, the simplified configurationfile copying equipment and the readable storage medium also have the above technical effects.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, device and readable storage medium for copying thin provisioned files. Background technique [0002] The basic principle of thin provisioning (Thin Provision) is "allocation on write", that is, the space seen by upper-layer applications and users is only virtual storage space, which does not occupy physical disk space, and is only allocated when data is written. Allocate physical disk space, so thin provisioning technology can improve the utilization and flexibility of physical storage devices, provide larger storage space at a lower cost, and realize the "super-provisioning" function of storage. [0003] However, thin provisioning is configured for hosts and files. For example: host A is configured with thin provisioning, but host B is not configured, then after copying the file stored in host A in thin provisioning mode to host B, the file will be...

AI Technical Summary

Problems solved by technology

For example: host A is configured with thin provisioning, but host B is not configured, then after copying the file stored in host A in thin provisioning mode to host B, the file will be stored in host B in the normal way, that is, originally After the files stored in the thin provisioning mode are copied across hosts, they become thick provisioned files, so that the files lose the advantages of thin provisioning in host B
