Problems solved by technology
Among them, each directory in the file storage path has its own metadata object. If the metadata object of a directory is lost or damaged, the subdirectories or files included in this directory will not be accessible, thus reducing the distributed storage capacity. The service performance of the system affects the user's access experience

This application discloses a metadata object restoration method, including: obtaining the target file, querying the storage path of the target file according to the identification information of the target file; respectively judging whether the metadata object of each target directory exists; if not, creating the target file The metadata object of the directory, and the target key-value pair calculated according to the directories and / or files included in the target directory is added to the metadata object. This application can determine its storage path according to any file in the distributed storage system, and when the metadata object of any directory in the storage path does not exist, calculate and obtain the target key value according to the directories and / or files included in the directory Yes, adding the target key-value pair to the metadata object newly created for the directory completes the restoration of the metadata object of the current directory, thereby improving the service performance of the distributed storage system. The metadata object restoration device, equipment, and readable storage medium disclosed in the present application also have the above-mentioned technical effects.
Description
Technical field [0001] The present application relates to the field of computer technology, in particular to a metadata object repair method, apparatus, apparatus and readable storage medium. Background [0002] Data stored in distributed storage systems includes metadata and data. Metadata is used to describe the attribute information of a directory or file, and the data is the data and content in the file. Where, each directory in the file storage path has its own metadata object, if the metadata object of a directory is lost or corrupted, then the subdirectories or files included in this directory will not be accessible, thereby reducing the service performance of the distributed storage system and affecting the user's access experience. [0003] Therefore, how to repair the metadata object of the directory, is a problem that those skilled in the art need to solve. Contents of the Invention [0004] In view of this, the object of this application is to provide a metadata obj...
