Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
The core of the invention is to provide a disk control method of a distributed storage system, so as to relatively reduce the operation complexity when a user controls the disk of the distributed storage system, thereby relatively reducing the labor cost and improving the user experience. The other core of the invention is to provide a disk control device, equipment and medium of the distributed storage system.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Implement method
Fig. 1 is a flowchart of a disk control method of a distributed storage system according to an embodiment of the present invention. Referring to fig. 1, the specific steps of the disk control method of the distributed storage system include:
step S10: and receiving a disk address and operation contents transmitted by a user through a preset unified control interface.
It is emphasized that the steps in the method are not performed manually by a user, and the execution subject of the method is a computing device, and the computing device takes the execution steps of the method as preset execution logic and executes the execution logic automatically in the form of software or scripts. The computing device may be specifically a computer, a server, a mobile terminal, or the like, and needs to have a data processing capability, and on this basis, the data processing capability may be determined according to an actual scene requirement, which is not further limited herein.
In this step, the nature of the unified control interface is API (application programming interface), which contains some predefined functions for the purpose of providing the user with the ability to access and control certain software or hardware without accessing the source code or understanding the details of the internal working mechanism. The step responds to the calling of the user through the unified control interface provided for the user, when the user needs to control the disk in the distributed storage system, the unified control interface is called, the disk address and the operation content are transmitted to the unified control interface, and then a series of subsequent steps are essentially execution logic inside the unified control interface. The disk address in the step refers to a physical address or a logical address which can uniquely represent the position of the disk in the communication process, so that the corresponding target disk can be accurately found according to the disk address; the operation content represents the specific operation performed by the user on the target disk, and since the method is not focused on controlling what kind of operation is performed on the disk, the method is not specifically limited to the operation content.
Step S11: and acquiring the disk type of the corresponding target disk according to the disk address.
It should be noted that, on the basis that the corresponding target disk can be obtained through the disk address, since the disks constituting the storage type storage cluster may come from different design vendors, and then there is a case that the operation interfaces of the disks of different design vendors are incompatible, it is necessary to call the corresponding operation interfaces to control the disks of different design vendors, and the disk type representation in this step is the design vendor to which the target disk belongs. In the process of communicating with the disk, the disk can return the relevant attribute information of the disk to the communication initiating device, so that the acquisition of the disk type corresponding to the target disk according to the disk address can specifically initiate a communication request to the disk address in advance, and further acquire response data containing the relevant attribute information of the disk returned by the target disk under the disk address, so that the disk type to which the target disk belongs is correspondingly acquired according to the attribute information in the response data.
Step S12: and calling a target control interface corresponding to the disk type to establish a control relation of the target disk.
The target control interface in this step is an inherent control interface of the target disk, and since the corresponding and inherent control interface of the target disk needs to be used when the target disk of different disk types is controlled, the step calls the target control interface corresponding to the disk type to establish the control relationship of the target disk. Since the details of the specific operation for calling the control interface of the disk are well known to those skilled in the art, they are not described herein.
Step S13: and executing the operation content on the target disk based on the target control interface.
It should be noted that, because the control interface of the disk includes a series of control functions invoked when the disk is controlled correspondingly, in this step, after the control relationship to the target disk is established through the target control interface, the target control function corresponding to the operation content transmitted by the user is selected from the control functions preset by the target control interface and executed, so as to implement the execution of the operation content expected by the user on the target disk based on the target control interface.
The disk control method of the distributed storage system provided by the invention comprises the steps of firstly receiving a disk address where a target disk is located and operation contents of the target disk, which are transmitted by a user through a preset unified control interface, further finding out the disk type of the corresponding target disk according to the disk address, further calling a corresponding target control interface according to the disk type, establishing a control relation of the target disk through the target control interface, and finally executing the operation contents required by the user on the target disk through the target control interface compatible with the target disk. The method is equivalent to unifying various interfaces used by the user for controlling the disk, when the user controls the disk in the distributed file system, the user can call the corresponding target control interface for the target disk required to be controlled by the user only by calling the unified control interface to transmit the disk address and the operation content, and then the target control interface is controlled to execute the operation content required by the user, so that the corresponding operation control for the target disk is realized, and the user can control each disk without repeatedly replacing the operation interface, so that the operation complexity of the user for controlling the disk of the distributed storage system is relatively reduced, the labor cost is relatively reduced, and the user experience is improved.
Example two
On the basis of the above examples, the present invention also provides a series of preferred embodiments as follows.
As a preferred embodiment, the calling a target control interface corresponding to a disk type to establish a control relationship for a target disk specifically includes:
and instantiating the target control interface based on the disk address to establish a control relationship to the target disk.
In the present embodiment, the target control interface is instantiated based on the disk address, and the disk address is essentially used as an input parameter of the target control interface, so that the target control interface is set as a control interface facing the target disk. In view of the fact that the same target control interface may need to be used by multiple users at the same time, the embodiment adopts a method of instantiating the target control interface, and when the target control interface needs to be used by a user, the target control interface is instantiated, so that when the target control interface is used by multiple users at the same time, each instantiated object of the target control interface occupies different memory space in the system and is independent of each other, thereby ensuring that the target control interface can be used by multiple users at the same time, and relatively ensuring the overall calling efficiency of the user for the target control interface.
In addition, as a preferred embodiment, after executing the operation content on the target disk based on the target control interface, the method further includes:
and when the idle time of the control relation reaches a preset threshold value, the target control interface is cancelled.
Because the computing device needs to continuously occupy the communication resources between the computing device and the target disk by establishing the control relationship between the computing device and the target disk through the target control interface, after the operating content is executed on the target disk based on the target control interface, if the control relationship is still maintained, the normal establishment of the control relationship on other disks by the computing device may be influenced.
In addition, as a preferred embodiment, the obtaining of the disk type of the corresponding target disk according to the disk address specifically includes:
and obtaining the disk type according to the disk address in a preset corresponding relation list.
In consideration of initiating a communication request to a disk address in advance and further acquiring response data which is returned by a target disk under the disk address and contains the attribute information related to the target disk, the communication request to the disk address needs to be initiated in advance according to a mode of obtaining the disk type of the target disk in the response data, so that communication resources between the target disk and the disk are occupied, and in actual use, a user controls the disk relatively frequently, so that the overall frequency of initiating the communication request to the disk address is relatively high, and further, the communication resources between the target disk and the disk are probably occupied in a large amount, so that the normal operation of calling a control interface and controlling the disk by a computing device is influenced, therefore, the disk address and the disk type of the corresponding target disk are recorded in a preset corresponding relation list in the embodiment, and further, the corresponding disk type can be obtained according to the disk address in the corresponding relation list, the occupation of communication resources between the computing equipment and the disk is reduced, and the normal operation of controlling the disk by the computing equipment is ensured.
In addition, on the basis of the above series of embodiments, as a preferred embodiment, before acquiring the disk type of the corresponding target disk according to the disk address, the method further includes:
judging whether a corresponding target disk exists under the disk address;
if yes, executing the step of obtaining the disk type of the corresponding target disk according to the disk address;
otherwise, sending abnormal information to the user.
It should be noted that, in consideration of the fact that a user may have a misoperation when inputting a disk address, the user may not be able to correspond to a corresponding target disk according to the disk address, in order to ensure that the user can learn that an exception exists in this case, in this embodiment, before obtaining a disk type of a corresponding target disk according to the disk address, first, it is determined whether the corresponding target disk exists under the disk address, and if the corresponding target disk does not exist under the disk address, exception information is sent to the user to notify the user that the disk address has an error, so as to ensure that the user learns the exception and eliminates the exception in time, thereby relatively improving the overall efficiency and the use experience of the user in controlling the disks of the distributed storage system.
