Problems solved by technology

[0003] The inventor found that if there is an ever-increasing large file, the user still has remaining space in the storage volume from the perspective of the storage volume, but when it occupies a storage block, it will fail to write, because a file cannot span two However, the existing technology cannot achieve reliable and flexible storage space scheduling when writing large files, and it is easy to fail to write large files.

Abstract

The embodiment of the invention provides a storage space data processing method and device for a distributed file system, and the method comprises: carrying out the use information prediction according to the change rate of the storage space use information of a target storage volume in a set time period, and obtaining the storage space use information prediction data; and executing a corresponding storage space allocation operation on the target storage volume according to a comparison result of the storage space use information prediction data and a preset use threshold. According to the method and the device, the use condition of the storage space in the distributed file system can be accurately predicted, the corresponding storage space scheduling operation is timely and reliably executed, the large file writing failure condition is avoided, and the stable operation of the system is ensured.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a storage space data processing method and device of a distributed file system. Background technique [0002] The currently used distributed file storage system is a distributed file system based on the file system of the host computer. This distributed file system uses file systems on different servers as storage blocks, and multiple storage blocks form a storage volume and provide it to user. The distributed file system distributes files to different storage blocks through scheduling under the non-striping strategy. [0003] The inventor found that if there is an ever-increasing large file, the user still has remaining space in the storage volume from the perspective of the storage volume, but when it occupies a storage block, it will fail to write, because a file cannot span two However, the existing technology cannot achieve reliable and flexible storage space s...
