The invention discloses a management method of a file storage system, which is applied to a metadata server and comprises the following steps: receiving an access request sent by a client and determining an access object of the client according to the access request; if the access object is a file object, sending a mapping relation between a file and a back-end storage node to the client, so thatthe client performs reading and / or writing operation on the file object according to the mapping relation, and after the writing operation is completed, updating corresponding file metadata; and if the access object is file metadata, performing corresponding operation on the file metadata according to the access request. According to the method, the file metadata operation and the file object operation are subjected to path separation, the I / O bottleneck problem can be effectively relieved, and the access performance of a file storage system is improved. The invention further discloses a management device of the file storage system, a metadata server and a computer readable storage medium which all have the above technical effects.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a method for managing a storage file system; it also relates to a management device for a storage file system, a metadata server, and a computer-readable storage medium. Background technique [0002] File metadata is important data that organizes the entire storage file system. It is mainly used to record the original information of each file, such as the creation time of the file, the file ID, and the cluster node where the file is located. Among them, the semantics of file metadata operations are completely different from file I / O operations. Usually, file metadata operations are more complex and have lower parallelism. Moreover, the current management method of the storage file system usually has an I / O bottleneck problem, which seriously affects the access performance of the storage file system. [0003] In view of this, how to alleviate the I / O bottleneck problem ...
