Problems solved by technology
Fast pools are expensive, so fast pools have less space
Since the data is first written into the fast pool, when the water level of the fast pool is high, that is, when there is a lot of data written in the fast pool, if the data in the fast pool cannot be migrated out in time, the newly created data cannot be written into the fast pool , resulting in the risk of the fast pool being written through, affecting the overall performance of the storage system

The invention discloses a file migration method based on file grading. The file migration method comprises the steps of querying whether a high-water-level data pool exists or not, wherein the high-water-level data pool is a data pool of which the data volume reaches a preset percentage; when the high-water-level data pool does not exist, sequentially migrating all the files to be migrated in theindex table; when the high-water-level data pool exists, migrating the files to be migrated in the high-water-level data pool in the index table one by one, and inquiring whether the high-water-leveldata pool still exists or not after the files to be migrated in the high-water-level data pool are migrated each time; and when the high-water-level data pool does not exist, sequentially migrating the remaining files to be migrated in the index table. According to the method, the fast pool can be prevented from being written through, and the overall performance of the storage system is improved.The invention furthermore discloses a file migration device and equipment based on file grading, and a computer readable storage medium, which all have the above technical effects.
Description
technical field [0001] The present application relates to the technical field of distributed storage, and in particular to a file migration method based on file classification; and also relates to a file migration device, equipment and computer-readable storage medium based on file classification. Background technique [0002] The distributed storage system is a cluster composed of multiple file storage node servers. Files are stored in chunks, with objects as the basic unit, and a copy of data is supported on multiple nodes. Each node can obtain a complete file through inter-node communication. data. When a node goes down, complete data recovery can be performed according to the configured strategy, which has the characteristics of high availability, high performance, and high scalability. Each node provides a metadata server for various metadata access operations to balance business pressure. A distributed storage system will be configured with fast pools such as solid-s...
