Problems solved by technology

[0002] The total number of files or subdirectories in each directory in a distributed system is different. In the user scenario, when the client continues to create directories or files in a large directory, the pressure on the metadata server to which the large directory belongs is relatively high, and the pressure on other metadata servers Smaller, stressed metadata servers impact

Abstract

The directory exporting method provided by the invention comprises the following steps: after a directory creating command is executed, determining directories of which the total number of sub-directories and files reaches a preset number in the directories as target directories; collecting metadata information of each target directory to form a target migration list; traversing the target migration list, and sequentially exporting each target directory to a corresponding target metadata server, wherein the load value of the target metadata server is smaller than that of the metadata server towhich the corresponding target directory belongs. Therefore, the method can realize automatic export of the directory, thereby improving the working efficiency and avoiding influencing the throughputof the distributed system. The invention further provides a directory exporting system and device and a computer readable storage medium which all have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of catalog export, and in particular to a catalog export method, system, device and computer-readable storage medium. Background technique [0002] The total number of files or subdirectories in each directory in a distributed system is different. In the user scenario, when the client continues to create directories or files in a large directory, the pressure on the metadata server to which the large directory belongs is relatively high, and the pressure on other metadata servers Smaller, stressed metadata servers affect file or directory creation performance, which in turn affects distributed system throughput. Related technologies need to export large directories to metadata servers with less pressure through manual export, which requires human intervention and high operability. Only administrators who are quite familiar with distributed systems can make corresponding adjustments, resulting in lo...
