Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0041] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are to distinguish two entities with the same name but different parameters or parameters that are not the same, see "first" and "second" It is only for the convenience of expression, and should not be construed as a limitation on the embodiments of the present invention, which will not be described one by one in the subsequent embodiments.

[0042] It should be noted that the Network File System (NFS) is a network abstraction above the file system, allowing remote clients to access it through the network in a manner similar to the local file system. Superblock: It can be understood as t...

Abstract

The invention discloses a file access method, which comprises the following steps of: in response to a received file access request, judging whether a preset directory needs to be traversed or not according to the request; acquiring super block information in response to the fact that the preset directory needs to be traversed; determining a mounting directory where the to-be-accessed file is located according to the attribute of the to-be-accessed file and the super block information; and in response to the fact that the to-be-accessed file is under the determined mount directory, accessing the to-be-accessed file. The invention further discloses a system, computer equipment and a readable storage medium. According to the scheme provided by the invention, the mounting directories of a plurality of NFS clients can be mounted under the same directory, and load balancing can be carried out according to the super block information, namely IO loads are loaded to different NFS servers.

Description

technical field [0001] The invention relates to the field of distributed storage, in particular to a file access method, system, device and storage medium. Background technique [0002] For better compatibility, distributed storage usually provides storage (NAS) services for external applications on some nodes of the storage system through a NAS gateway. The application host side uses the NFS service to mount the storage locally, and access the storage through the mounted directory. Since the NFS protocol is a standard protocol, most applications on the application host can run normally without any modification. [0003] Usually, each NFS mounted directory on the application host side corresponds to an NFS service. In some cases, applications have higher performance requirements for storage, and this one-to-one C / S architecture will become a performance bottleneck. Contents of the invention [0004] In view of this, in order to overcome at least one aspect of the above ...
