Abstract

The invention provides a hot metadata access control method and a server. The method includes: receiving metadata write operation requests sent by a client terminal; applying a metadata storage lock for a metadata storage lock module to lock read and write operations of metadata of the metadata storage lock module; reading metadata information from the metadata storage lock module, and writing the metadata information read from the metadata storage lock module into a metadata cache module; according to metadata information and write operation requests in the metadata cache module, generating new metadata information, writing the new metadata information into the metadata cache module; applying a metadata write lock for the metadata cache module to lock read and write operations of metadata of the metadata cache module; writing the new metadata information into the metadata cache module, releasing the metadata write lock; releasing the metadata storage lock.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a hotspot metadata access control method and server. Background technique [0002] Metadata access is a function based on a distributed file system. Generally, a distributed file system includes a client and a server, wherein metadata and related information can be stored on the server. [0003] When the client needs to access metadata, the client can send an operation request to the server, such as a read operation request or a write operation request. Taking the write operation request as an example, first, the client sends a write operation request to the metadata business module of the server, and then the metadata business module applies for a metadata write lock from the metadata read-write lock module to lock the metadata storage module and The metadata cache module, and after locking, write the newly generated metadata information into the metadata ...
