Embodiment Construction

[0066] The core of the present invention is to provide a data migration method of a storage server, which can effectively perform data migration of the storage server, ensure load balance, and improve data migration efficiency.

[0067] In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0068] Please refer to figure 2 , figure 2 It is an implementation flowchart of a data migration method of a storage server in the present invention, and the data migration method of the storage server ...

Abstract

The invention discloses a data migration method, system and device for a storage server and a storage medium, and the method comprises the steps: determining the number n of strips to be migrated according to the storage information of the storage server after m disks are newly inserted; selecting n to-be-migrated stripes from the c full stripes according to a preset migration rule, selecting a to-be-migrated data block from the n to-be-migrated stripes, and migrating the to-be-migrated data block to the newly inserted disk, so that after migration is completed, the difference between the stripe usage amounts of any two disks in the storage server does not exceed 1; and determining the data content of the verification data block of each stripe to complete the data migration of the storage server, and determining the data content of the verification data block of the c-n stripes in a manner of incremental updating of erasure codes for the c-n stripes which are not selected as the to-be-migrated stripes in the c stripes. By applying the scheme of the invention, the data migration of the storage server can be effectively carried out, the load balance is ensured, and the data migration efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of coding, and in particular, to a data migration method, system, device and storage medium of a storage server. Background technique [0002] At present, in the face of the storage requirements of massive data, distributed storage has been widely used. The number of nodes in a distributed storage system is large, the reliability of a single node is usually not very high, and due to software and hardware failures, human errors and other reasons, the system often has node failures. Therefore, in order to improve the data reliability of the distributed storage system and realize the reconstruction of the original file, a certain amount of data redundancy will be stored on the basis of storing the original data, so that in the case of some node failures, it is still possible to The original file is decoded and restored to ensure the normal operation of the system.
