Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The embodiment of the disclosure provides a data storage method, which is applied to a terminal device, wherein the terminal device is configured with a check Disk, the check Disk is a common Hard Disk, for example, an HDD (Hard Disk Drive), an SSD (Solid State Disk Drive), and the like, and the terminal device is a computer provided with a windows system or a linux system or an unix system, as shown in fig. 1, and the method comprises the following steps:
The target operation instruction is used for indicating writing target data or reading target data.
For example, a client software is installed on the terminal device, where the client software is a software developed based on the ISCSI protocol and used for logging in to connect to a target storage space created by the storage server, and the client software detects each operation instruction in real time, and the target operation instruction may be an instruction for writing target data or an instruction for reading target data.
And 102, executing the operation indicated by the target operation instruction on the check disk when the target network is determined to be disconnected.
The target network is a network in which the terminal equipment is connected with a target storage space in the storage server.
When the target operation instruction is detected, whether the target network connected between the terminal equipment and the target storage space of the storage server is normally connected or not is firstly determined, and when the target network is determined to be disconnected, the operation indicated by the target operation instruction cannot be executed in the target storage space, and all the detected operations corresponding to the target operation instruction are redirected to the check disk, namely, the operation indicated by the target operation instruction is executed only on the check disk. The operation executed by the target operation instruction comprises a target data writing operation or a target data reading operation, namely when the target network is disconnected, only target data is read on the check disc, and the target data read in the check disc is returned to an operating system of the terminal equipment for normal display by using a disc recovery algorithm. When writing target data on the check disk, a disk backup algorithm is used to write the target data on the check disk. The disk recovery algorithm is to invert the data of the check disk according to binary bits, and the disk backup algorithm is to invert the data of the target storage space according to binary bits.
For example, when the target network is disconnected and then restored, the first current file system information in the target storage space and the second current file system information on the check disc need to be acquired, where the first current file system information includes a first current file system attribute, a first current sector storage location, a first current file size, and a first current file timestamp, and the second current file system information includes a second current file system attribute, a second current sector storage location, a second current file size, and a second current file timestamp.
When the first current file system information and the second current file system information are acquired, comparing each piece of information in the first current file system information with each piece of information corresponding to the second current file system information, and when each piece of information in the first current file system information is determined to be consistent with each piece of information corresponding to the second current file system information, indicating that the data stored in the target storage space is consistent with the data stored in the check disk; when the information in the first current file system information is determined to have information inconsistent with the corresponding information in the second current file system information, the data stored in the target storage space is inconsistent with the data stored in the check disk, and at the moment, the second current file system information is required to be synchronized into the target storage space according to a disk recovery algorithm, so that the data in the target storage space and the data in the check disk are ensured to be kept synchronized.
The embodiment of the disclosure provides a data storage method, wherein a check disc is configured on a terminal device, and when the terminal device is determined to be disconnected with a target storage space in a storage server, an operation indicated by a target operation instruction is executed on the check disc, namely target data is read or written on the check disc; when the network is determined to be disconnected and the connection is restored, the first current file system information in the target storage space is compared with the second current file system information on the check disk, when the first current file system information and the second current file system information are determined to be inconsistent, the data in the target storage space is indicated to be lost, and at the moment, the second current file system information on the check disk is synchronized in the target storage space. Therefore, even if the network disconnection occurs, after the network is restored, the terminal equipment can normally read the data from the storage server, so that the reliability of data reading is improved.
The embodiment of the disclosure provides a data storage method, which is applied to a terminal device, wherein a check disc is configured on the terminal device, as shown in fig. 2, and the method comprises the following steps:
The connection request carries an IP (Internet Protocol Address ) address of the storage server, identification information of a target storage space and identification information of a check disk.
The terminal device is provided with a client software, the client software displays a connection interface, a user can input the IP address of the storage server, the identification information of the target storage space and the identification information of the check disk on the connection interface, and then clicks a connection key to enable the terminal device to acquire a connection request carrying the IP address of the storage server, the identification information of the target storage space and the identification information of the check disk, and send the connection request to the storage server.
When receiving a connection request sent by a terminal device, a storage server analyzes the connection request, acquires an IP address of the storage server, identification information of a target storage space and identification information of a check disk, searches a corresponding target storage space in a database according to the identification information of the target storage space, acquires reference identification information of the check disk in the target storage space when searching the corresponding target storage space, determines whether the reference identification information is empty, compares the reference identification information with the acquired identification information of the check disk when determining that the reference identification information is not empty, establishes network connection between the terminal device and the target storage space of the storage server according to the IP address of the storage server and the identification information of the target storage space when determining that the reference identification information is identical to the acquired identification information of the check disk, and sends attribute information of the target storage space to the terminal device after the network connection is successful.
And 203, receiving attribute information of the target storage space sent by the storage server.
And 204, displaying the target storage space according to the attribute information of the target storage space.
For example, when the terminal device receives the attribute information of the target storage space sent by the storage server, the virtual disk driver module in the client software analyzes the attribute information of the target storage space to obtain the size of the target storage space, LUN (Logical Unit Number ) information of the target storage space, and loads the target storage space into one or more disk block devices, and at this time, on the client operating system, the corresponding target storage space of the storage server can be seen.
The target operation instruction is used for indicating writing target data or reading target data.
Optionally, acquiring a first current file system in the target storage space and a second current file system on the check disk; and detecting the target operation instruction when the first current file system is determined to be consistent with the second current file system.
After the target storage space is displayed, the terminal equipment needs to verify the availability of the target storage space, namely, a first current file system in the target storage space and a second current file system in a check disk are acquired, each piece of information in the first current file system is correspondingly compared with each piece of information in the second current file system, when each piece of information in the first current file system is determined to be consistent with each piece of information corresponding to each piece of information in the second current file system, the target storage space is indicated to be normally used, namely, data can be read and written in the target storage space normally, and the data can be checked, so that a target operation instruction can be detected at the moment; when the information in the first current file system is determined to have information inconsistent with the corresponding information in the second current file system, the target storage space cannot be normally used at present, and the second current file system needs to be synchronized into the target storage space to enable the target storage space to be normally used, so that the data in the target storage space and the data in the check disk are synchronized.
And 206, writing the target data in both the check disk and the target storage space when the target network is not disconnected and the target operation instruction is used for indicating to write the target data.
For example, when the terminal device determines that the target network is normally connected, and detects an operation instruction for writing target data, the terminal device writes the target data in two parts, one part is written in the target storage space, and the other part is written in the test disc by using a disc backup algorithm.
For example, when the terminal device determines that the target network is normally connected, and when an operation instruction for reading target data is detected, the target data is read from the target storage space and returned to an operating system of the terminal device for display.
And step 208, when the disconnection of the target network is determined, executing the operation indicated by the target operation instruction on the check disk.
The target network is a network in which the terminal equipment is connected with a target storage space in the storage server.
For example, when the terminal device determines that the target network is disconnected, the operation indicated by the target operation instruction cannot be executed in the target storage space, and only the operation indicated by the target operation instruction is executed on the check disk. I.e. writing or reading target data only on the parity disk when the target network is disconnected.
For example, when the target network is disconnected and then the connection is restored, the first current file system information in the target storage space and the second current file system information on the check disk need to be acquired.
When the first current file system information and the second current file system information are acquired, comparing each piece of information in the first current file system information with each piece of information corresponding to the second current file system information, and when each piece of information in the first current file system information is determined to be consistent with each piece of information corresponding to the second current file system information, indicating that the data stored in the target storage space is consistent with the data stored in the check disk; when the information in the first current file system information is determined to have information inconsistent with the corresponding information in the second current file system information, the data stored in the target storage space is inconsistent with the data stored in the check disk, and at the moment, the second current file system information is required to be synchronized into the target storage space according to a disk recovery algorithm, so that the data in the target storage space and the data in the check disk are ensured to be kept synchronized.
The embodiment of the disclosure provides a data storage method, wherein a verification disk is configured on a terminal device, when the terminal device is determined to be normally connected with a target network of a target storage space in a storage server, target data are written on the target storage space and the verification disk, and the data are read in the target storage space; when the disconnection of the target network is determined, reading target data or writing the target data on the check disk; when the network is determined to be disconnected and the connection is restored, the first current file system information in the target storage space is compared with the second current file system information on the check disk, when the first current file system information and the second current file system information are determined to be inconsistent, the data in the target storage space is indicated to be lost, and at the moment, the second current file system information on the check disk is synchronized in the target storage space. Therefore, even if the network disconnection occurs, after the network is restored, the terminal equipment can normally read the data from the storage server, so that the reliability of data reading is improved.
The embodiment of the disclosure provides a data storage method, applied to a storage server, wherein the storage server is a common storage server in the market, and is provided with storage management software based on an ISCSI (Internet Small Computer System Interface, small computer system interface) protocol, as shown in fig. 3, the method comprises the following steps:
The connection request carries the IP address of the storage server, the identification information of the target storage space and the identification information of the check disc.
When receiving a connection request sent by a terminal device, a storage server analyzes the connection request to obtain an IP address of the storage server, identification information of a target storage space and identification information of a check disc, wherein a generation algorithm of the identification information of the check disc is as follows: and obtaining a hardware identification number of the check disc, and encrypting the hardware identification number through an MD5 algorithm to obtain identification information of the check disc, wherein the MD5 algorithm is an algorithm specified in a protocol.
For example, the storage server searches the corresponding target storage space in the database according to the identification information of the target storage space, and when the corresponding target storage space is found, acquires the reference identification information of the check disc stored in the target storage space, and determines whether the reference identification information is empty.
For example, when it is determined that the reference identification information is not empty, that is, is not empty, it is described that the connection request is not received for the first time, and it is required to determine whether the identification information of the check disc is identical to or not to the reference identification information.
And 304, when the identification information of the check disc is identical to the reference identification information, establishing connection between the terminal equipment and the storage server according to the IP address of the storage server and the identification information of the target storage space.
For example, when it is determined that the identification information of the check disc is identical to the reference identification information, a network connection between the terminal device and the target storage space of the storage server is established according to the IP address of the storage server and the identification information of the target storage space.
After the network connection is successful, the storage server sends the attribute information of the target storage space to the terminal device, so that a virtual disk driver module in client software of the terminal device analyzes the attribute information of the target storage space to obtain the size of the target storage space, LUN information of the target storage space loads the target storage space into one or more disk block devices, and at the moment, the corresponding target storage space of the storage server can be seen on a client operating system.
An embodiment of the present disclosure provides a data storage method, applied to a storage server, as shown in fig. 4, including the following steps:
For example, the storage server creates a target storage space with a certain capacity according to the requirement, and the specific creation method may refer to a storage space creation method in the prior art, which is not described herein in detail.
For example, when the storage server creates the target storage space, the storage server allocates corresponding identification information for the target storage space, that is, the identification information of the target storage space, where the identification information is IQN information, and the IQN information is used to identify unique names of the single ISCSI target and the initiator.
And step 403, correspondingly storing the target storage space and the identification information of the target storage space.
For example, when the target storage space is created and the identification information of the target storage space is allocated, the correspondence relationship between the target storage space and the identification information of the target storage space is stored in the database.
The connection request carries the IP address of the storage server, the identification information of the target storage space and the identification information of the check disc.
It should be noted that, according to the different determination results of the reference identifier information, the following steps are also different, and when the reference identifier information is determined to be non-empty, step 407 and steps 409 to 411 are performed; upon determining that the reference identification information is empty, steps 408 to 411 are performed.
And 408, when the reference identification information is determined to be empty, storing the identification information of the check disk in correspondence with the target storage space.
For example, when the reference identification information is determined to be empty, it is described that the storage server receives the connection request for the first time, and at this time, the correspondence between the identification information of the check disc in the connection request and the identification information of the target storage space and the correspondence between the identification information of the check disc in the connection request and the target storage space are stored in the database.
