detailed description

The embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

Embodiment 1:

In order to achieve the purpose of the system disk replacement and the rapid recovery of the service in the case that the server device is powered off, the embodiment of the present disclosure provides a system disk management method, and the specific process is shown in FIG. 1 .

S101. Obtain disk data of a system disk.

By analyzing the important files and necessary files in the system disk, and collecting the version files and data files of the business, the backup configuration files that need to be backed up are prepared.

S102. Back up the disk data in the memory to generate a memory image file.

According to the previous backup configuration file, the files and data to be backed up in the obtained system disk are compressed to generate a memory image file, which is stored in the memory as a backup file of the running operating system.

S103. After the system disk is updated, use the memory image file to perform disk data recovery on the system disk.

The system disk update includes replacing the new system disk, and replacing the new system disk can replace the system disk by hot swapping, so that the entire server device does not need to be powered off. After the replacement is complete, the memory image file in the memory is rewritten to the new system disk, which can quickly restore the system operation.

The system disk management method provided by the embodiment of the present disclosure can complete the replacement of the system disk and the rapid recovery of the service, and improve the service quality of the user, by backing up the disk data in the memory.

Obviously, those skilled in the art should understand that the update of the solution system disk of the embodiment of the present disclosure further includes reinstalling the system on the system disk, rewriting the memory image file in the memory to the system disk, and restarting the system operation. If the solution of the embodiment of the present disclosure is applied to another scenario, corresponding changes to the content of the solution should also be considered as belonging to the protection scope of the present disclosure.

Embodiment 2:

The embodiment of the present disclosure provides a system disk management method. For details, see FIG. 2 .

S201, setting a backup configuration file.

S202. Read data stored in a system disk, and use the read data as disk data.

According to the backup configuration file, the data stored in the system disk is read, and the read data is taken as the disk data to be backed up.

S203. Back up the disk data in the memory to generate a memory image file.

The previously read disk data to be backed up is compressed to generate a memory image file, which is stored in the memory as a backup file of the running operating system.

S204. Monitor data in a backup configuration file of the system disk.

According to the backup configuration file, periodically traverse the file path or directory path in the configuration file, and compare the current data with the generated memory image file data according to a specific algorithm.

S205. Determine whether the data is updated. If not, the process returns to S204; if yes, the process goes to S206.

After all the data has been detected in the loop, it is judged based on the comparison result whether the data is updated. If not, the data is not updated according to the comparison result, and the process returns to S204 to continue monitoring the data in the backup configuration file of the system disk; if yes, the data is updated according to the comparison result, and the process goes to S206.

S206. Determine whether the data is new data. If yes, go to S207; if no, go to S208.

After judging that the data is updated according to the comparison result, it is judged that the updated data file is added to the attribute, and two types of new data and updated data are added. The newly added data is the first time the data file is written to the memory image file. Before this data file is created, it needs to be created. The updated data is written to the memory image file before the data file, and the original memory image file needs to be deleted. Then, the new data is added to the image file through the compression algorithm to complete the update.

S207: Generates a memory image file of the newly added data in an incremental manner.

At this time, the updated data file is newly added data, and the memory image file of the newly added data is generated in an incremental manner. Incremental mode means that when the updated disk data is newly added, that is, the data file is completely generated for the first time, all the data is directly packaged into an image file according to the compression algorithm and stored in the memory as a memory image file.

S208: Generate a memory image file of the updated data by using a differential method.

At this time, the updated data file is updated data, and a memory image file of the updated data is generated in a differential manner. The differential mode means that when the disk data is updated before the data file exists, the original memory image file is deleted, and the new data is added to the image file through the compression algorithm and stored in the memory as a memory image file.

S209. Monitor an update message for characterizing the update system disk.

Updating the system disk involves replacing the new disk or repairing the disk, and you need to rewrite the operating system-related data on the disk. Replacing a new system disk can replace the system disk by hot swap, so you do not need to power off the entire server device.

S210, shielding the memory from reading and writing to the system disk.

When the update message is detected, it indicates that the system disk needs to be updated. At this time, the memory is read and written to the system disk and other related actions. The memory can no longer make any changes to the data in the system disk, ensuring that the memory is running at this time. The information is separated from the operating system disk to ensure that the operating system does not change reset during disk operations such as disk replacement. Because I have been synchronizing the data in the backup system disk. At this time, the memory is read and written to the system disk. It can also avoid the difference between the actual data on the disk and the data in the memory image file during the time difference between re-importing data. The system is unstable after the system disk is replaced.

S211. Monitor a recovery message used to represent the recovery system disk.

Restoring the message requires writing the in-memory memory image file to the current system disk. It can be delivered by the user after updating the system disk.

S212: Write the memory image file back to the updated system disk to generate a corresponding image file.

When the recovery message is detected, the memory image file is extracted from the memory, and the updated system disk is written back to the system disk, and the corresponding image file is generated at the corresponding disk location.

S213, extract the image file.

After the image file is generated, the image file is decompressed and released to the corresponding specific directory to restore the system environment, service version, and data.

S214. Determine whether the update system disk is successful. If yes, go to S215; if no, go to S216.

After the recovery of the system disk is completed, it is detected whether the data update is completed, whether the operating system can run normally, and if so, it is judged that the update system disk is successful, and the process goes to S215; if not, the process goes to S216.

S215, restore all system disk operation functions.

Before the memory is read and written to the system disk and other related actions, all system functions on the system disk are restored, and the system runs normally.

S216, the prompt requires manual intervention processing.

If it is judged that the update of the system disk fails, the prompt message informs that manual manual intervention processing is required, and the update system disk processing can be re-executed.

The system disk management method provided by the embodiment of the present disclosure can restore the recovery of the system disk and the disk data by backing up the disk data in the memory, without interrupting the service service, and improving the user service quality.

Obviously, those skilled in the art should understand that if the solution of the embodiments of the present disclosure is applied to other scenarios, corresponding changes to the content of the solution should be considered as belonging to the protection scope of the present disclosure.

Embodiment 3:

The embodiment of the present disclosure provides a system disk management method. For details, see FIG. 3 .

S301. Set a backup configuration file.

The backup configuration file contains the data such as the necessary files required for the operating system to run. It analyzes the important files and necessary files on the system disk and collects various types of files.

S302. Create a disk image file of the system disk.

According to the backup configuration file, read the data stored in the system disk, create a corresponding disk image file on the system disk, and use the disk image file as the disk data.

S303. Create a memory image file of the system disk.

Create a memory image file in the memory corresponding to the disk image file based on the disk image file created as disk data on the system disk.

S304. Monitor the disk image file.

According to the backup configuration file, periodically traverse the file path or directory path in the configuration file, and compare the current data with the generated disk image file data according to a specific algorithm.

S305. Determine whether the data is updated. If not, the process returns to S304; if yes, the process goes to S306.

After all the data has been detected in the loop, it is judged based on the comparison result whether the data is updated. If not, the data is not updated according to the comparison result, and the process returns to S304 to continue monitoring; if so, the data is updated according to the comparison result, and the process proceeds to S306.

S306. Update the disk image file.

After judging that the data is updated according to the comparison result, it is judged that the updated data file is added to the attribute, and two types of new data and updated data are added. The newly added data is that the data file is written to the disk image file for the first time. There is no such data file before. In this case, the hard disk image file is updated in an incremental manner. Incremental mode means that when the disk data is newly added, that is, the data file is completely generated for the first time, all the data is directly packaged into an image file according to the compression algorithm and stored in the disk as a disk image file.

The update data is already written to the disk image file before the data file, and the hard disk image file is updated in a differential manner. The differential mode refers to deleting the original disk image file when the disk data is updated data, that is, the data file. The new data is added to the image file through the compression algorithm and stored in the disk as a disk image file.

S307. Update the memory image file to be consistent with the disk image file.

After the disk image file is updated, the memory image file is updated to maintain the consistency of the two image data. You can also compare disk image files and memory image files periodically to determine whether the two mirrored data are consistent. Before updating the memory image file, you can mask the memory read and write operations on the system disk and other related actions. The memory can no longer make any changes to the data in the system disk, so that the system disk data does not change anymore, so the disk image file is not If the disk image file is changed when the memory image file is updated, the two mirrored data of the memory image file and the disk image file cannot be consistent. After the memory image file is updated, you can restore the memory to the system disk read and write operations and other related actions.

Updating the memory image file requires judging that the updated data file is added to the attribute, and there are two types of new data and updated data. The newly added data is the first time that the data file is written into the memory image file. In the incremental mode, the updated data is directly packaged into an image file and stored in the memory according to the compression algorithm, as a memory image file.

The update data is written to the memory image file before the data file is deleted. The original memory image file is deleted in a differential manner, and the new data is added to the image file through the compression algorithm and stored in the memory as a memory image file.

S308. Monitor an update message for characterizing the update system disk.

S309, the memory is read and written to the system disk.

When listening to the update message, the memory is read and written to the system disk and other related actions, the memory can no longer make any changes to the data in the system disk, ensuring that the information running in the memory is separated from the operating system disk. To ensure that the operating system does not change reset during disk operations such as disk replacement. Because the data in the backup system disk has been synchronized before, the memory is read and written to the system disk at this time, and the data in the disk can be prevented from being different from the data in the memory image file during the time difference of re-importing data. The system is unstable after the system disk is replaced.

S310. Monitor a recovery message used to represent the recovery system disk.

S311: Write the memory image file back to the updated system disk to generate a corresponding image file.

S312, extract the image file.

S313. Determine whether the update system disk is successful. If yes, go to S314; if no, go to S315.

After the recovery of the system disk is completed, it is detected whether the data update is completed, whether the operating system can run normally, and if so, it is judged that the update system disk is successful, and the process goes to S314; if not, the process goes to S315.

S314, restore all system disk operation functions.

S315, prompting that manual intervention is required.

The system disk management method provided by the embodiment of the present disclosure can back up the memory image file in the backup process by establishing a disk image file to back up the disk data in the disk and then synchronizing the memory image file in the memory. The memory does not need to be traversed each time. Back up the configuration file and synchronize it with the disk image file at regular intervals to reduce the read/write IO (Input/Output, Input/Output interface) operations between the disks and reduce the CPU (Central Processing Unit) usage. It can effectively solve the problem of high CPU synchronization between the CPU and the system disk when the high frequency synchronization between the existing RAID disks is completed, and at the same time complete the recovery of the system disk and disk data, without interrupting the service service and improving the user service quality.

Embodiment 4:

The embodiment of the present disclosure provides a system disk management device, and FIG. 4 is a specific schematic diagram. The following describes each module and function further, including:

The backup module 401 is configured to obtain disk data of the system disk, back up the disk data in the memory, and generate a memory image file.

Before you can obtain the disk data of the system disk, you need to set the backup configuration file. The backup configuration file contains the operating system. The catalog of necessary data such as necessary files is compiled by analyzing various important files and necessary files on the system disk and collecting various types of files.

The obtaining the disk data of the system disk includes reading the data stored in the system disk according to the backup configuration file, and using the read data as the disk data. Backing up disk data in memory generates a corresponding memory image file based on the read data.

Obtaining the disk data of the system disk also includes monitoring the disk image file created on the system disk and using the disk image file as the disk data. In this way, a disk image file is created in the system disk, and then a corresponding memory image file is created in the memory according to the disk image file.

After the memory image file is generated, you need to monitor whether the disk data in the backup configuration file changes. If the change indicates that the disk data needs to be updated. If it changes, you need to judge whether the data file attribute to be updated is new data or updated data. Different update methods are used depending on the attributes. When the disk data is newly added, the memory image file of the newly added data is generated in an incremental manner; when the disk data is updated data, the memory image file of the updated data is generated in a differential manner. The newly added data is the first time the data file is written to the memory image file. Before this data file is created, it needs to be created. The updated data is written to the memory image file before the data file, and the original memory image file needs to be deleted. Then, the new data is added to the image file through the compression algorithm to complete the update.

The recovery module 402 is configured to use the memory image file to perform disk data recovery on the system disk after the system disk is updated.

The recovery module is configured to listen for update messages used to characterize the update system disk, including updating the new disk or repairing the disk. When listening to the update message, the memory is read and written to the system disk, and the memory can no longer make any changes to the data in the system disk, ensuring that the information running in the memory is separated from the operating system disk at this time, and the disk is guaranteed to be replaced. The operating system does not change reset during the update disk operation. Because the data in the backup system disk has been synchronized before, the memory is read and written to the system disk at this time, and the data in the disk can be prevented from being different from the data in the memory image file during the time difference of re-importing data. The system is unstable after the system disk is replaced.

The recovery module is also configured to listen for recovery messages used to characterize the recovery system disk. When the recovery message is detected, the memory image file is written back to the updated system disk, the image file is generated, the image file is decompressed, and the file is released to the corresponding specific directory to restore the system environment, service version, and data.

The system disk management device provided by the embodiment of the present disclosure can restore the recovery of the system disk and the disk data by backing up the disk data in the memory, without interrupting the service service, and improving the user service quality.
