Problems solved by technology

Currently, NFS-Ganesha v4 adopts the NFSv4ACL draft, and the distributed file system adopts the POSIX ACL draft. Because NFSv4ACL has finer granularity than POSIX ACL permission control, it is usually very complicated to map any NFSv4ACL to POSIX ACL with the same semantics. Therefore, the two documents There is a problem of permission control incompatibility between systems, and there is currently no method for docking distributed file system permission control for NFS-Ganesha v4 version

Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0054] The present invention provides a permission control method across file systems, such as figure 1 shown, including the following steps:

[0055] S101. Mount the network file system NFS-Ganesha v4 service on the network file system client;

[0056] S102. Receive a network file system client's request for obtaining or setting an ACL extended attribute, and convert it into a Linux standard system call request;

[0057] Among them, the ACL extended attribu...

Abstract

The invention discloses a cross-file system permission control method, device and equipment and a storage medium. The method comprises the steps that mounting a network file system NFS-Ganasia v4 version service mounted on the client side; receiving an ACL extension attribute obtaining or setting request of the client, and converting the ACL extension attribute obtaining or setting request into alinux standard system calling request; packaging the calling request into a remote procedure calling function and sending the remote procedure calling function to a network file system server; when the calling request received by the server corresponds to the request for obtaining the ACL extension attribute, calling the distributed file system to obtain the authority control extension attribute;and when the call request corresponds to the request for setting the ACL extension attribute, calling the distributed file system to set the authority control extension attribute. In this way, NFS-canbe solved through the above steps. And the problem that the version of the Ganna v4 protocol cannot be compatible with the distributed file system POSIX ACL standard authority control list proposal is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device, device and storage medium for cross-file system authority control. Background technique [0002] NFS-Ganesha (Network File System user-space) is a user-mode network file system. In the case of system service failure, it has better manageability and maintainability than kernel-mode NFS, and user-mode NFS-Ganesha is easy to implement and Therefore, at present, massive distributed object storage NFS-Ganesha is widely used. [0003] The distributed file system has the characteristics of reliability, automatic rebalancing, and automatic recovery. According to the division of scenarios, the distributed file system can be divided into three major blocks, namely object storage, block device storage, and file system services. The advantage of the distributed file system over other storage is that it is not only for storage, but also makes full use of the ...
