[0002] In order to improve the redundancy and reliability of the operating system and data, a hardware disk array (Redundant Arrays of Independent Disks, RAID) controller is usually used to configure the RAID1 mode. This approach can maintain the stable operation of the operating system and the security of data when a hard disk fails. However, if the hardware RAID controller fails, it will cause data loss or system downtime; and the firmware source code based on the hardware RAID controller is not public, which makes it difficult to determine the cause when the operating system has problems; in addition, the closed nature of hardware RAID also limits its customization and secondary development capabilities, reducing the flexibility and scalability of the system.

[0003] Based on the above problems, there are three improvement schemes in the related art: Scheme 1 is a software RAID scheme based on the Basic Input-Output System (BIOS); Scheme 2 is to partition the disk first and configure some partitions as RAID, but the boot partition (BIOS-BOOT or UEFI-EFI) and the area outside the partition (such as Bootloader) are not included in the RAID configuration; Scheme 3 is to use three disks, set the part not included in the RAID in Scheme 2 separately on one disk (as a boot disk), and the other two disks are partitioned first and then configured as RAID according to needs, or RAID is established first and then partitioned, and used as system disks. However, the schemes in the related art have the problem of relying on specific hardware, and make the system startup process too complicated. Summary of the invention

It should also be noted that any step in the embodiments of the present application can be independently executed by the device, that is, when the device executes any step in the following embodiments, it may not rely on the execution of other steps.

[0051] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] The present application provides a control method, which can be applied to control a device. Figure 1 As shown, the method may include the following steps:

[0053] Step 101: Determine a target logical disk for multiple physical disks of a system of a control device.

[0054] The target logical disk has a data mapping relationship with a plurality of physical disks.

[0055] In the embodiment of the present application, the multiple physical disks may refer to the system disk of the control device itself, that is, the disk used to control the host system of the control device and the boot system to start the normal operation. The target logical disk may be a software disk created based on the multiple physical disks; wherein the multiple physical disks may be hardware RAID, then the target logical disk may refer to software RAID.

[0056] Step 102: Run a boot system of a control device based on the first driver files on the multiple physical disks.

[0057] The first driver file is a driver file corresponding to the boot system.

[0058] In an embodiment of the present application, the boot system may refer to a BIOS or a Unified Extensible Firmware Interface (UEFI) system; the first driver file may refer to a file containing data required to enable the boot system to start and run normally.

[0059] It should be noted that the control device can read the first driver file from the physical disk, and run the boot system based on the first driver file.

[0060] Step 103: Read the second driver files on the multiple physical disks through the target logical disk.

[0061] The second driver file is a driver file corresponding to the host system of the control device.

[0062] In the embodiment of the present application, the second driver file may refer to a file containing data required for starting and operating the host system of the control device; the host system may refer to the operating system of the control device itself.

[0063] It should be noted that the control device can read the target logical disk, so as to read the second driver file on the physical disk through the target logical disk.

[0064] Step 104: Start the host system based on the second driver file and the boot system.

[0065] The control device may use the second driver file to start and run the operating system of the control device by booting the system.

[0066] The control method provided by the embodiment of the present application can directly run the boot system according to the first driver file corresponding to the boot system on the physical disk, and start the host system through the second driver file corresponding to the host system read by the logical disk of the physical disk and the boot system. It does not need to rely on specific hardware devices, nor does it need to set up a boot program for each physical disk independently. It solves the problem of relying on specific hardware in related technologies and reduces the complexity of the system startup process.

[0067] Based on the above embodiments, the present application provides a control method, referring to Figure 2 As shown, the method may include the following steps:

[0068] Step 201: A control device determines a target logical disk for multiple physical disks of a system of the control device.

[0069] The target logical disk has a data mapping relationship with a plurality of physical disks.

[0070] In the embodiment of the present application, a software RAID array (i.e., a target logical disk) is first created based on a physical disk, and then the software RAID array is partitioned, and finally a boot method is created on the software RAID array. Specifically, Figure 3 As shown in the figure, you can create a software RAID (i.e. / dev / md127) for the hard disk 1 and hard disk corresponding to the system; then, partition the software RAID into the following Figure 3 The following partitions are shown: / dev / md127p1, / dev / md127p2, / dev / md127p3 and / dev / md127p4; and, / dev / md127p1 corresponds to the FAT partition, / dev / md127p2 corresponds to the BOOT partition, / dev / md127p3 corresponds to the ROOT root partition, and / dev / md127p4 corresponds to other partitions; finally, a boot loader can be created; and GRUB2 can be used as the Bootloader.

[0071] It should be noted that by creating a software RAID, full disk mirroring redundancy can be achieved, including areas outside the partitions such as the Bootloader, Master Boot Record (MBR) or GUID Partition Table (GPT).

[0072] Step 202: The control device runs a boot system of the control device based on the first driver files on the multiple physical disks.

[0073] The first driver file is a driver file corresponding to the boot system.

[0074] Step 203: If the second target data is read on multiple physical disks, the control device reads the second driver files on the multiple physical disks through the target logical disk.

[0075] The second target data is used to drive the target logical disk.

[0076] In the embodiment of the present application, for different boot programs, the second target data can be read from different locations on multiple physical disks; and, for different boot programs, the specific content of the second target data is different.

[0077] It should be noted that after the second target data is read, it means that the target logical disk needs to be read next, that is, the host system needs to be started through the target logical disk.

[0078] In the embodiment of the present application, step 203 may be implemented by steps 203a to 203b, or step 203 may be implemented by steps 203c to 203d:

[0079] Step 203a: Control the device to read data at the first position of the plurality of physical disks.

[0080] If the boot system is BIOS, data can be read from the first position of multiple physical disks; specifically, Figure 4 The first position shown in may be the position between the gap after the MBR and the boot (BOOT) partition.

[0081] It should be noted that step 203a can be implemented in the following ways:

[0082] Step 203a1: The control device reads the value of the target format at the first position of the plurality of physical disks.

[0083] The target format is a binary format; the value of the target format is the binary value of core.img. Specifically, when the boot system is BIOS, Figure 5 As shown, the target driver information can be stored in core.img.

[0084] Step 203b: If the target driver information for the target logical disk is read at the first position, the control device reads the second driver files on the multiple physical disks through the target logical disk.

[0085] The second target data includes target driving information.

[0086] In the embodiment of the present application, the target driver information may refer to the target binary value corresponding to the driver module in the binary value corresponding to core.img at the first position of the plurality of physical disks. Figure 5 As shown, the target drive information may refer to the binary value corresponding to mdraid09.mod.

[0087] In other embodiments of the present application, by loading the mdraid09 module in the pre-boot phase of GRUB, GRUB can identify the target logical disk composed of software RAID and its partitions and file systems in the subsequent boot phase. In this way, once the basic runtime environment of GRUB is successfully loaded, GRUB has the ability to access the grub.cfg configuration file in the target logical disk of the software RAID.

[0088] Step 203c: Control the device to read data at the second position of the plurality of physical disks.

[0089] If the boot system is UEFI, data can be read from the second location of multiple physical disks; specifically, Figure 6 The second position shown in may be the location of the FAT partition.

[0090] It should be noted that step 203c can be implemented in the following ways:

[0091] Step 203c1: Control the device to read the target file at the second position of the multiple physical disks.

[0092] The target file is a file for storing GRUB basic runtime components. Specifically, when the boot system is UEFI, such as Figure 5 As shown, the target drive information can be stored in the target file.

[0093] Step 203d: If the target driver information for the target logical disk is read at the second position, the control device reads the second driver files on the multiple physical disks through the target logical disk.

[0094] In the embodiment of the present application, the target drive information may refer to a file where data corresponding to a drive module for driving a target logical disk at a second position among the plurality of physical disks is located.

[0095] It should be noted that the GRUB basic runtime environment and the software RAID driver module are loaded at the same time in the early stage of the GRUB boot code; specifically, during the GRUB initialization process, in addition to loading basic runtime components such as the device framework, file handles, environment variables, and command line parser in rescue mode, the mdraid09 driver module used to identify the soft RAID is also loaded.

[0096] In other embodiments of the present application, "reading the second driver files on multiple physical disks through the target logical disk" in steps 203b and 203d can be implemented in the following manner:

[0097] A. The control device reads first target data of a target logical disk from target locations of multiple physical disks.

[0098] In the embodiment of the present application, the first target data is used to describe the target logical disk; the target position may refer to a position in multiple physical disks that does not affect the traditional layout of the disks. In a feasible implementation, the first target data may refer to metadata of the target logical disk, and the target position may refer to the last position of the physical disk.

[0099] It should be noted that after reading the software RAID driver modules on multiple physical disks, it can be determined that the software RAID needs to be read next; at this time, the metadata of the software RAID can be read from the end of the physical disk to facilitate subsequent reading of the software RAID.

[0100] B. The control device reads the target logical disk based on the first target data to read the second drive files on the multiple physical disks.

[0101] In the embodiment of the present application, after the metadata of the software RAID is read, the software RAID can be read based on the metadata, so that the second driver file on the physical disk corresponding to the software RAID can be read.

[0102] Step 204: The control device starts the host system based on the second driver file and the boot system.

[0103] In other embodiments of the present application, the method may further include the following steps:

[0104] Step 205: The control device determines the first target data corresponding to the target logical disk.

[0105] Step 206: Control the device to store the first target data to target locations of multiple physical disks.

[0106] In an embodiment of the present application, the metadata of the software RAID is stored at the very end of the physical disk, which can avoid the overlap of the metadata of the software RAID with the traditional layout of the physical disk (such as Bootloader, MBR, GPT partition table). This also means that the metadata of the software RAID will not interfere with the MBR, the gap after MBR, or the GPT partition table at the front end of the physical disk; wherein, the MBR, the gap after MBR, or the GPT partition is the key information used by UEFI or BIOS to identify the disk and partition at startup. Therefore, at the beginning of system startup, UEFI or BIOS will process the software RAID member disk in the same way as a non-software RAID disk, read the MBR or EFI system partition of the physical disk without being interfered by the software RAID metadata, so that it can find the Bootloader and continue the boot process.

[0107] It should be noted that the control method of the present application does not rely on any specific hardware. It only requires two physical disks to achieve full disk mirroring redundancy and supports the two mainstream boot modes of BIOS / MBR and UEFI / GPT. In this way, after replacing any physical disk, there is no need to re-create a boot program for the new physical disk or use other strategies to synchronize the BIOS-BOOT or UEFI-EFI boot partition. Therefore, each physical disk can maintain the boot capability, which greatly simplifies the complexity of the software RAID1 configuration.

[0108] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0109] The control method provided by the embodiment of the present application can directly run the boot system according to the first driver file corresponding to the boot system on the physical disk, and start the host system through the second driver file corresponding to the host system read by the logical disk of the physical disk and the boot system. It does not need to rely on specific hardware devices, nor does it need to set up a boot program for each physical disk independently. It solves the problem of relying on specific hardware in related technologies and reduces the complexity of the system startup process.
