Embodiment Construction
[0050] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure.
[0051] It should also be noted that in some alternative implementations, the functions / acts noted may occur out of the order noted in the figures. For example, two figures shown in succession may, in fact, be executed substantially concurrently or may sometimes be executed in the reverse order, depending upon the functionality / acts involved.
[0052] The present invention will be further described below in conjunction with the accompanying drawings and preferr...

A distributed storage internal storage management method and system, and a computer storage medium, the method comprising: dividing an internal storage management module into a plurality of different size data block types (S110); writing a file to a first node, and setting a lease for the file, such that the file is bound to the first node (S120); in the internal storage, corresponding the file to a data block type, dividing the file in the internal storage into one or a plurality of data blocks of the same size, and simultaneously generating data block access context, the data block access context comprising data block navigation and the associated file coding (S130); storing the data blocks and the access context in the first node and updating the version (S140); when a file is written to the second node and the lease of the file is already held by the first node, then the first node receives the file forwarded by the second node, writes the file to the local storage of the first node, and updates the version (S150). The data writing is a data block-based operation, such that the file can support random writing in the distributed storage.
Description
technical field [0001] The present invention relates to the field of storage technology, and more specifically, to a distributed storage memory management method, system and computer storage medium. Background technique [0002] A distributed storage system stores data dispersedly on multiple independent devices. Traditional network storage systems use centralized storage servers to store all data. Storage servers become the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. The distributed network storage system adopts a scalable system structure, uses multiple storage servers to share the storage load, and uses the location server to locate and store information. It not only improves the reliability, availability and access efficiency of the system, but also is easy to expand. [0003] In a distributed storage system, the existing memory management method cannot efficiently complete ...
