Embodiment Construction
[0101] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0102] In order to solve the above-mentioned technical problems, embodiments of the present invention provide a method and device for storing, reading, and clearing data, and a cloud storage system. The cloud storage system can be as figure 1 As shown, it includes a management node and a plurality of storage nodes (storage node 1, storage node 2, storage node 3, storage node 3...storage node N), wherein each storage node includes M storage blocks, and N storage blo...

The embodiment of the present invention discloses a data storage, reading, and cleaning method, device, and cloud storage system. The storage blocks in the storage nodes are formed into resource pools one by one, and data storage, reading, and data storage are performed in units of resource pools. Cleaning up reduces the workload of management. Especially during data cleaning, only the data in each resource pool is cleaned up, specifically, for each resource pool, determine the first number of occupied storage blocks in the resource pool; determine whether the first number meets the preset data Clearing condition; if yes, send a clearing data instruction to the storage node where each occupied second storage block in the resource pool is located, so that the storage node clears the data stored in the second storage block it includes. That is to say, the management node determines the number of occupied storage blocks in the resource pool, and when the number meets the preset data cleaning conditions, the data in the storage blocks is cleaned, the process is simple, and the workload of the management node is reduced.
Description
technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a data storage, reading and cleaning method, device and cloud storage system. Background technique [0002] The cloud storage system includes a management node and a storage node. The storage node is a physical medium for storing data, and the management node manages the data stored by each storage node in the system. [0003] Usually, the storage node reports the metadata information of the data stored by itself to the management node, and the management node manages the data stored by each storage node according to the received metadata information. for example: [0004] When a device needs to store data in a storage node, the device sends a resource request to the management node, and the management node allocates a storage node for the device according to the resource request and the metadata information reported by each storage node, and the device stores the ...
