Referring to FIG. 2, a schematic flowchart of a first implementation manner of a mounting method of a disk array of the present application, the method for mounting a disk array includes:

Step S10: Receive RAID1 configuration information input by the user, generate corresponding disk array information, and obtain information about the disk in the Android system.

In step S20, when the number of disks corresponding to the disk information is greater than or equal to 2, a corresponding disk array interface is created according to the disk array information;

In step S30, the disk array interface is used to control the driver to map the disk set to the corresponding disk array device file according to the disk array information, and the disk in the Android system is determined according to the disk array device file. Mount to the Android system.

Specifically, the present application is applied to an Android system. In this embodiment, the Android system can be as shown in FIG. 3. The Android system can include a configuration module, an array creation module, and a RAID controller. The foregoing steps can be implemented by each module. RAID technology is the core processing technology of storage disk arrays, and its purpose is to improve the efficiency and fault tolerance of data processing. The storage system generally adopts the necessary means to ensure the performance of the system. The usual method is to set the cache system. The caching system is a virtualized system that works by efficiently processing I/O requests to improve performance. RAID1 is in mirror mode. RAID 1 uses redundancy to enable data to store peer-to-peer data on the corresponding disk. The same piece of data can be stored on two disks. When the data in a disk is frequently operated, the system can read the same piece of data directly from another disk. Therefore, RAID1 allows but block disk failure and system performance is not directly affected. This mode requires two disks, preferably at the same speed. In addition, RAID1 is a member disk composed of different capacity disks. The total capacity will depend on the disk with the smallest capacity. The remaining disk space of the remaining block can no longer read and write data. As a result, disk capacity utilization is low and the overall RAID capacity is reduced by almost 50%. Therefore, in the case of a large number of writes to RAID 1, the performance of writing may become very poor. Specifically, the configuration module is configured to receive configuration information of the RAID 1 of the disk array input by the user, where the configuration information of the RAID 1 includes an array level configuration, a disk configuration, and the like, where the user may enter the Android first when inputting the RAID 1 configuration information of the disk array. Device in the system Driver, enter the submenu, select Mutiple devices driver support (RAID and in the submenu) LVM) Enter the RAID level selection menu and select RAID-1 in the RAID level selection menu to complete the configuration information of the input RAID RAID1.

Then, the corresponding disk array information is generated according to the configuration information of the disk array, and the disk configuration file is imported into the array creation module in the Android system; the array creation module creates an interface corresponding to the RAID1 in the Android system according to the disk array information generated by the configuration module. Then the controller calls the interface created on the Android system to control the underlying driver to perform the mounting operation by using a system call. Specifically, the driver maps the disk connected to the Android system to the disk array device according to the level information of the RAID1. File, and then hang the disk in the Android system on the Android system according to the disk array device file. Further, the step of mounting the disk array to the Android system according to the disk array device file includes:

The full name of vold is volume Daemon. In fact, it is responsible for completing the daemon of the system's CDROM, USB mass storage, MMC card and other extended storage mount tasks. The main feature it provides is support for hot plugging of these storage peripherals. It is roughly divided into three steps: 1. Creating a link: In vold as a daemon, on one hand, it accepts the driven information and passes the information to the application layer; on the other hand, it accepts the upper layer command and completes the corresponding. So there are two links here: (1)vold Socket: responsible for vold and application layer information transfer; (2) access to udev socket: responsible for vold and the underlying information transfer; these two links are created at the beginning of the process. 2. Boot: This is mainly the processing of existing peripheral storage devices when vold is started. First, load and parse vold.conf and check if the mount point has been mounted. Second, perform an MMC card mount; finally, handle USB mass storage. 3. Event processing: Here, by monitoring the two links, completing the processing of the dynamic event, and responding to the upper application operation, the disk in the Android system is mounted to the Android system in the above manner.

Further, referring to FIG. 4, FIG. 4 is a schematic flowchart of a second implementation of a method for mounting a disk array according to the present application. Based on the embodiment shown in FIG. 2, the host of the disk array in the embodiment includes:

Step S40, receiving a read and write instruction sent by the application;

Step S50, performing read and write operations on the disk array device file by the driver according to the read/write command.

After the mounting is performed in step S30, the disks in the Android system form a mapping relationship with the disk array, so that the application reads and writes the disk array file as if the U disk is read or written. Specifically, the user can operate through the application program or the application itself generates a read/write instruction, and then reads and writes the disk array device file through the driver, thereby performing read and write operations on the disk.

Further, referring to FIG. 5, FIG. 5 is a schematic flowchart of a third implementation of the mounting method of the disk array of the present application. According to the embodiment shown in FIG. 2, the mounting method further includes:

Step S60, detecting the state of the RAID 1 of the disk array, and obtaining state information of the corresponding RAID 1 of the disk array;

Step S70: When the preset status information is detected, the report is reported to the Android system.

Specifically, for the convenience of use, in the actual use process, a monitoring module is configured in the Android system for performing the steps in this embodiment, and the monitoring module can detect the state of the RAID 1 of the disk array in real time or periodically. When the state of the RAID 1 RAID array is reported, the status of the disk array is reported to the Android system. The manner in which the status of the disk array is reported to the Android system may be performed by using the information reported in the Android system, and is not described in detail in this embodiment.

Further, referring to FIG. 6, FIG. 6 is a schematic flowchart of a fourth implementation of a method for mounting a disk array according to the present application, where the mounting method further includes:

Step S80: Send broadcast information of the Android system, where the broadcast information includes disk array RAID1 error information, and increase broadcast information of the disk array RAID1 and the disk array RAID1 to be mounted, so that the application receives the disk array RAID1 error, When the broadcast information of the RAID 1 or RAID 1 mount information of the disk array is increased, the corresponding processing is performed;

In step S90, when it is detected that the disk in the RAID 1 is abnormal, the corresponding disk array interface is automatically reconstructed.

Step S100: When the disk array RAID1 reconstruction condition is not satisfied, the broadcast information of the additional error data is sent, so that the application performs corresponding processing according to the broadcast information.

When the Android system receives the status information of the disk array, it can determine the status of each disk in the disk array RAID1, determine whether each disk has an error or abnormality, and the Android system broadcasts the status information of each disk array RAID1 in real time or periodically. If the application receives the disk array RAID1 error or increases the broadcast information, the corresponding processing is performed. Specifically, if the broadcast information of the RAID 1 error of the disk array is received, the corresponding RAID 1 level of the disk array is used. Processing, specifically: if the current RAID level of the disk array is RAID1, and the broadcast information of one disk error in the disk array is received, at this time, because other disks can continue to be used, the corresponding prompt information can be displayed, thereby prompting the user to replace Disk; if you receive a broadcast that increases the disk array, re-synchronize, that is, the newly added disk synchronizes the contents of the normal disk; if you receive the broadcast of the disk array RAID1, the corresponding mount information is displayed. Further, if an abnormal broadcast of all the disks in the RAID 1 is received, the RAID 1 interface of the disk array is rebuilt. If the reconstruction of the RAID 1 is not satisfied, the broadcast information with the additional error is sent. The application is caused to perform corresponding processing when receiving the broadcast information, such as displaying corresponding prompt information to prompt the user.

Further, referring to FIG. 7 , FIG. 7 is a schematic flowchart of a fifth implementation of a method for mounting a disk array according to the present application. According to the embodiment shown in FIG. 2 , the mounting method further includes:

Step S110, receiving a query instruction input by a user;

Step S120: Query the current state information of the RAID 1 of the disk array according to the query instruction, and display the information.

In order to facilitate the user to view the data of the disk array and control the disk in time, the present embodiment also provides a view function of the disk array. Specifically, the user can perform a query operation on the operation interface, and the Android device generates a corresponding query instruction according to the user operation. Then, according to the query instruction triggered by the user, the current state information of the RAID 1 of the disk array is queried and displayed on the Android device, thereby implementing the query function.

Further, based on the embodiment shown in FIG. 2, the mounting method further includes:

In step S130, when receiving the expansion command input by the user through the application, the RAID 1 format disk determined by the expansion command is used to expand the capacity on the corresponding RAID 1 interface by using the expansion command; or

Step S140: When receiving a disk deletion instruction input by the user through the application, the RAID1 interface determined by the disk deletion instruction deletes the RAID1 format disk corresponding to the disk deletion instruction in the corresponding RAID1 according to the disk deletion instruction. And rebuild RAID1 after deleting the disk; or,

Step S150: When receiving an add/delete command of the hot spare disk input by the user through the application, the RAID1 interface determined by the add/delete command adds/delete the corresponding RAID1 according to the add/delete command. Add/delete the RAID1 format hot spare disk corresponding to the instruction.

In order to avoid the situation that some disks are used for a long time, the disks are aged, or the disk storage space is insufficient, in this embodiment, a management function is also provided in the embodiment, specifically, when receiving the expansion command triggered based on the operation interface. The RAID 1 and the RAID 1 format disk corresponding to the expansion command are obtained, and the RAID 1 format disk to be added is added to the RAID 1 through the RAID 1 interface corresponding to the expansion command to implement RAID 1 expansion. Preferably, the RAID 1 to be added is obtained. The format disk determines whether the expanded RAID1 meets the requirements of the RAID1 level according to the number of disks to be added in the RAID1 format. If the requirements are met, the capacity expansion operation is performed. Otherwise, the error message is output.

When the disk deletion instruction triggered by the operation interface is received, the RAID 1 format disk corresponding to the disk deletion instruction is determined, and the RAID 1 interface corresponding to the disk deletion instruction is deleted in the RAID 1 corresponding to the disk deletion instruction. After the RAID 1 format disk is deleted, the RAID 1 after the disk is deleted is rebuilt. Preferably, when the RAID 1 after the disk is deleted meets the requirements of the level of the RAID 1 , the RAID 1 may be directly reconstructed, or the RAID 1 format disk with the same number of disks to be deleted may be selected to reconstruct the RAID 1 after the disk is deleted. To ensure that the capacity of the RAID1 after the disk is deleted is unchanged; when the RAID1 after the disk is deleted does not meet the requirements of the RAID1 level, select the other RAID1 format disk with the same number of disks to be deleted. After the RAID1 is rebuilt.

When receiving an add/delete command of the hot spare disk triggered by the operation interface, determining a hot spare disk corresponding to the add/delete command, by using the RAID1 interface corresponding to the add/delete command, in the add/delete command Delete the hot spare disk in the corresponding RAID1.
