Problems solved by technology

[0003] However, since the local file system can only be mounted and read and write accessed by a single node in the cluster, when the CIFS client wants to access the data stored in the local file system, it can only send a request to the single cluster node that mounts the file system , but cannot be accessed through other nodes in the cluster, resulting in low utilization of cluster front-end network bandwidth and system performance degradation

Abstract

The invention discloses a data access method, device and equipment of an NAS cluster and a computer readable storage medium. A data forwarding layer is arranged between a CIFS service layer and a local file system layer in advance, and when a first node of an NAS cluster receives a data access request sent by a CIFS client, the data forwarding layer judges whether a mounting node of a local file system to which to-be-accessed data belongs is the first node or not; if so, the data access request is sent to a local file system corresponding to the first node, so that the first node directly returns a result to the CIFS client; if not, a target mounting node of a local file system to which the to-be-accessed data belongs is determined, the data access request is forwarded to the target mounting node, so that the first node feeds back the return result of the target mounting node to the CIFS client, so that a user can access data stored in the local file system through any node in the NAScluster, the complexity is low, the network bandwidth of the front end of the cluster is fully utilized, and the system performance is improved.

Description

technical field [0001] The present invention relates to the technical field of NAS clusters, in particular to a data access method, device, equipment and computer-readable storage medium for NAS clusters. Background technique [0002] In the NAS cluster system, the protocol layer uses CIFS, and the file system layer uses the cluster file system. All data is stored in a single file system, which is the namespace, so that any node in the cluster can access all data. Compared with the local file system, the cluster file system is more complex and difficult to maintain. In order to reduce the complexity of the file system layer of the NAS cluster, related technologies use a local file system instead of the cluster file system. [0003] However, since the local file system can only be mounted and read and write accessed by a single node in the cluster, when the CIFS client wants to access the data stored in the local file system, it can only send a request to the single cluster ...
