Problems solved by technology

The clustered NAS storage system supports clients to access the storage system through the CIFS and NFS sharing protocols. However, when accessing the storage system through different protocols, the same file in the same directory will be accessed. If it is not handled properly, an access conflict will occur and the data cannot be guaranteed. correctness

Embodiment Construction

[0008] Refer to the attached figure 1 The shared access method of the clustered NAS storage system proposed by the present invention is described in detail.

[0009] The invention provides a shared access method of a clustered NAS storage system, which solves the main problem that different clients access conflicts on the same directory through different sharing protocols. Specifically, the clustered NAS storage system is mounted on the head of the clustered NAS and provides services in the form of directories. Clients of the Windows operating system access the storage directory through the CIFS protocol, and use the user mode in CIFS to ensure the access rights of the Windows client user to the storage directory; for Linux or Unix operating system clients, access the storage directory through NFS, and Also specify NFS share access users. Of course, the CIFS access user and the NFS access user cannot be the same. Make sure that only one user has read, write, and operation pe...

Abstract

The invention provides a shared access method of a cluster NAS (network attached storage) system. The method has the advantage that different file reading, writing and operation authorities are set for a user using different cluster storage shared access protocols, so one file can only be modified by one user of the cluster storage shared access protocol, and the access conflict caused by different cluster storage shared access protocols accessing the same storage catalogue is avoided.

Description

technical field [0001] The invention relates to the field of computer storage, in particular to a shared access method for a clustered NAS storage system. Background technique [0002] At present, a large-scale clustered NAS storage system has many clients, and the clients have different operating systems such as windows, Linux, and Unix. How to enable clients of different operating systems to access the storage system is a key link. The clustered NAS storage system supports clients to access the storage system through the CIFS and NFS sharing protocols. However, when accessing the storage system through different protocols, the same file in the same directory will be accessed. If it is not handled properly, an access conflict will occur and the data cannot be guaranteed. correctness. The invention provides an effective solution to the problem that the client accesses the same directory of the storage system through different sharing protocols. Contents of the invention ...
