Problems solved by technology

At present, the access control authority of the volume connected to the storage device can only be judged when the client logs in. If you want to disconnect the access control authority of a certain client after the login is completed, you must log out / login again. In this way, It affects other volumes under the connected storage device, causing other volumes to be disconnected, affecting the normal operation of the business, and causing data loss and other problems

Abstract

The present application discloses an access control method, device, device, and medium. The method includes: using a preset iSCSI protocol capacity query algorithm to query the target information of the volume under the storage device connected to the iSCSI client; The target information judges whether there is an unauthorized access volume that the iSCSI client has no right to access in the volume under the storage device connected by the iSCSI client; if yes, then an error message is sent to the local kernel, so that the iSCSI client The volume without access is not accessed. In this way, the access control of volumes on the storage device side can be performed without affecting normal business operations, avoiding data loss and other problems, and realizing online modification of the access rights of different volumes on the same storage device side.

Description

technical field [0001] The present application relates to the field of distributed storage, and in particular, to an access control method, apparatus, device, and medium. Background technique [0002] In distributed storage, the iSCSI architecture mainly divides the storage device and the host used into two parts, namely: iSCSI target, which is the storage device side, storage disk or RAID (Redundant Arrays of Independent Disks, disk array) device, It is also possible to emulate a Linux host as an iSCSI target, in order to provide disks used by other hosts. The iSCSI initiator, that is, the client that can use the target, is usually the server. That is to say, the server that wants to connect to the iSCSI target must also install the relevant functions of the iSCSI initiator before it can use the disk provided by the iSCSI target. The client can establish a connection with the target through the above methods to access the underlying block storage library (librbd) to reali...
