[0004] However, in the above data reconstruction process, the number of disks involved in data reconstruction is small, and the writing speed of reconstructed data depends entirely on the performance of the hot spare disk. If the writing speed of the hot spare disk is low, the When there is a large amount of data, it will take a very long time

Embodiment Construction
[0019] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0020] To solve the problem of slow data writing speed in the data reconstruction process of the existing distributed storage system, the embodiment of the present application provides a data reconstruction method, which can be applied to the distributed storage system. Wherein, the distributed storage system includes at least two storage nodes, and e...

The embodiment of the invention provides a data reconstruction method and device, equipment and a storage medium. In the embodiment of the invention, the method comprises the steps of dividing disks on different storage nodes in the distributed system into a plurality of storage blocks, mapping one storage block belonging to the different storage nodes into a first block group, and storing data stored in the first block group in the storage blocks of the different storage nodes; when the system has a fault, determining a first storage block storing data from a fault disk; determining a second storage block which corresponds to the first block group together with the first storage block based on a mapping relationship between the storage blocks and the block groups, and selecting a third storage block; and creating a data reconstruction task for the first block group, controlling each non-fault storage node to execute the data reconstruction task, and reconstructing data in the first storage block into a third storage block. In this way, the data reconstruction task is created with the block group as the unit, the number of disks participating in the data reconstruction task is larger, the storage performance is higher, and the data reconstruction speed can be increased.
Description
technical field [0001] The present application relates to the technical field of distributed storage, and in particular to a data reconstruction method, device, device and storage medium. Background technique [0002] In order to meet the rapidly growing data storage needs of individuals and enterprises, a distributed storage system emerges as the times require. A distributed storage system generally includes multiple storage nodes, and each storage node has multiple storage disks. During use, storage nodes and storage disks will inevitably fail. In order to ensure data reliability, it is necessary to restore the data on the failed node or storage disk to other storage nodes or storage disks according to the data redundancy strategy. , this recovery process is called data reconstruction. [0003] In the existing distributed storage system, RAID technology is usually used for data reconstruction. In this data reconstruction scenario, the distributed storage system reserves a...
