Abstract

The invention relates to the technical field of data storage, in particular to a shared directory mounting method and a distributed network additional storage system. The method comprises the following steps: a management node receives a domain name resolution request sent by a client, and determines whether a table item corresponding to the client exists in a client list based on the domain name resolution request; if it is determined that the table item corresponding to the client does not exist in the client list, a virtual IP is allocated to the client, and the virtual IP is pushed to the first node, so that the first node establishes an association relationship with the client based on the virtual IP; the virtual IP is pushed to the client, so that the client sends a shared directory mounting request to the first node; table items corresponding to the clients are generated in the client list; after receiving a shared directory mounting request sent by a client, the first node judges whether the first node is a node executing access to a shared directory; and if the node is judged to execute access to the shared directory, a mounting operation of the shared directory is executed.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a method for mounting a shared directory and a distributed network-attached storage system. Background technique [0002] With the advent of the 5G era, the amount of global Internet and enterprise data is exploding, of which unstructured data accounts for more than 80% of the share. Distributed NAS cluster technology plays an important role in storing these unstructured data. With the growth of data scale, the deployment scale of distributed NAS clusters is getting larger and larger, and at the same time, higher requirements are put forward for distributed NAS clusters in terms of capacity and performance. [0003] A distributed NAS cluster usually provides NFS (Network File System, network file system) and CIFS (Common Internet File System, common Internet file system) services externally. When cephfs is used as the underlying implementation of the NAS cluster, ...
