Description
Technical Field
The present invention relates to the field of computer technologies, and in particular, to a disk control method, apparatus, server, and storage medium.
Background
In a server, multiple disks are typically configured to meet the storage needs of a user. When the server system is started, the server distributes the drive letter for the disk; when the server is provided with a first disk and a second disk, the first disk can be configured on the server through an onboard AHCI (Advanced Host Controller Interface, Chinese), so that the first disk is loaded through a loading AHCI drive; the second disk may be configured on the server through a RAID (Redundant array of Independent Disks, chinese) card or an SAS (Serial Attached SCSI, chinese) card, so that the second disk is loaded by loading the RAID card or the SAS card. Taking the above server architecture as an example, the allocation process of the disk identifier is generally as follows: when the AHCI driver is loaded first after the system is started, the first disk is identified and allocated with the drive letter "/dev/sda", and then when the RAID card or SAS card driver is loaded later, the second disk is identified later and allocated with the drive letter "/dev/sdb".
However, the inventor finds that, due to the fact that the allocation sequence of the disk signatures depends on the identification sequence of the disks, at the time of system restart, the AHCI driver load corresponding to the first disk may be later than the RAID card or SAS card driver load corresponding to the second disk, which may result in the second disk being identified first and then the first disk, and further the second disk may be allocated as "/dev/sda", and the first disk may be allocated as "/dev/sdb", which may result in disk misordering.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to fig. 1 to 6. It should be noted that the drawings provided in the present embodiment are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than being drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of each component in actual implementation may be changed arbitrarily, and the layout of the components may be more complicated.
Fig. 1 is a schematic flow chart of a disk control method according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S101: and when the drive letter sequence formed by the first drive letter of the first disk and the second drive letter of the second disk is inconsistent with the target sequence, determining a first drive module of the first disk and a second drive module of the second disk.
In specific implementation, a plurality of disks may be configured in the server, and for convenience of describing the disk control method of the present invention, the embodiment of the present invention will be described in detail by taking the first disk and the second disk as examples. The first disk can be configured on the server through an onboard AHCI interface, and the second disk can be configured on the server through a RAID card or an SAS card.
Further, the first drive letter of the first disk and the second drive letter of the second disk can be viewed through a viewing tool of disk information, which is not described in detail in the embodiment of the present invention. In an exemplary embodiment, the target sequence may be a predefined sequence, for example, a sequence of defining disks corresponding to onboard AHCIs is prior to a sequence of disks configured by a RAID card or an SAS card; thus, when the first drive letter of the first disk is acquired as 'sda' and the second drive letter of the second disk is acquired as 'sdb', the first disk is a disk corresponding to the onboard ACHI, and the order of the drive letters is first, it is determined that the disks are not out of order; and when the first drive letter of the first disk is acquired to be 'sdb' and the second drive letter of the second disk is acquired to be 'sda', the first disk is a disk corresponding to the onboard AHCI, and the disk sequence is back, so that the disk disorder can be judged.
Step S102: adjusting the loading sequence of the first driving module and the second driving module according to the target sequence; the first drive module is used for driving a first disk arranged on the first interface, and the second drive module is used for driving a second disk arranged on the second interface.
And when the disk disorder is determined, adjusting the loading sequence of the first drive module corresponding to the first disk and the second drive module corresponding to the second disk according to the target sequence, and ensuring the stability of disk identifier distribution of the disks through the control of the loading sequence of the drives.
In a first implementation case, in order to adjust a loading sequence of a first driver module and a second driver module, referring to fig. 2, a flowchart of a method for adjusting a loading sequence according to an embodiment of the present invention is shown. As shown in fig. 2, the method comprises the steps of:
step S201: and acquiring an image file, wherein the image file comprises drive files of a plurality of drive modules and is used for controlling the drive modules to load when the system is started.
In an exemplary embodiment, the image file may be an initamfs file, and the order of the loaded driver files is controlled by the initamfs file when the Linux system is started; wherein initramfs contains many disk drives that are necessary before the system actually loads the kernel.
Step S202: and determining a drive module to be loaded later from the first drive module and the second drive module according to the target sequence.
In an exemplary embodiment, according to the target sequence, the first disk needs to be loaded first, and the second disk needs to be loaded later; the first disk corresponds to a first driver module, the second disk corresponds to a second driver module, accordingly, the first driver module needs to be loaded first, the second driver module needs to be loaded later, and the driver module loaded later is further determined to be the second driver module.
Step S203: and deleting the drive file corresponding to the loaded drive module from the mapping file.
In the image file, the second driver file corresponding to the second driver module may be deleted. Therefore, when the system is started, the first drive module is guaranteed to be loaded firstly, so that the loading of the first disk is realized, the first disk is firstly identified and the drive letter is distributed, and the sequence of the disks is guaranteed.
In an exemplary embodiment, since the system is installed on an on-board AHCI disk device, the initialization of the operating system is not affected by removing the Raid/SAS driver mpt3SAS from the initramfs file, when initramfs completes the initialization of the on-board AHCI disk device, the on-board AHCI is allocated to the drive identifier sda, and the initialization of the Raid/SAS driver is performed in the subsequent kernel, and the Raid/SAS disk device is allocated to the drive identifier sdb. By the method, the initialization time of an onboard AHCI disk and the Raid/SAS disk drive can be staggered, so that the stability of the disk drive letter under the system is ensured.
In a second implementation case, referring to fig. 3, a flowchart of another loading order adjustment method provided in the embodiment of the present invention is shown. As shown in fig. 3, the method comprises the steps of:
step S301: and acquiring an image file, wherein the image file comprises drive files of a plurality of drive modules and is used for controlling the drive modules to load when the system is started.
Step S302: and when the mapping file further comprises a loading control file, modifying the loading sequence of the first drive module drive file and the second drive module drive file of the loading control file identifier according to the target sequence.
In a specific implementation, when the loading control file is included in the image file, the loading control file is used for controlling the loading sequence of the driver. The loading sequence of the first driver module driver file and the second driver module driver file in the loading control file can be further modified according to the target sequence. When it is determined that the loading of the first disk is prior to the loading of the second disk according to the target sequence, the first drive module drive file corresponding to the first disk may be modified in the loading control file prior to the second drive module drive file corresponding to the second disk. This ensures that the first disk is loaded and allocated with the drive letter first and the second disk is loaded and allocated with the drive letter later, thus ensuring the stability of the drive letter allocation.
In a third implementation case, referring to fig. 4, a flowchart of another method for adjusting a loading order according to an embodiment of the present invention is shown. As shown in fig. 4, the method comprises the steps of:
step S401: and acquiring an image file, wherein the image file comprises drive files of a plurality of drive modules and is used for controlling the drive modules to load when the system is started.
Step S402: and when the mapping file further comprises a loading control file, modifying the loading sequence of the first drive module drive file and the second drive module drive file of the loading control file identifier according to the target sequence.
Step S403: a driver loading sequence is obtained.
Step S404: and when the loading sequence of the first drive module and the second drive module is not consistent with the target sequence, determining a drive module which is loaded later from the first drive module and the second drive module according to the target sequence.
Step S405: and deleting the drive file corresponding to the loaded drive module from the mapping file.
In specific implementation, when the system is started, devices under the system may be scanned in sequence according to the sequence of bus serial numbers, and if an onboard AHCI device is scanned first, the AHCI driver creates a Thread _ AHCI Thread to independently process initialization of the AHCI disk device; it should be noted that the system does not wait for the Thread _ ahci Thread to perform the next Thread after completing initialization, but the Thread independently processes the subsequent initialization action, and the system immediately performs the Thread creation of the next device; if the Raid/SAS card device is scanned later, the Raid/SAS driver also creates a Thread _ sa Thread to independently process the initialization of the Raid/SAS card device, and the time interval between the creation of the Thread threads is very short, so that the Thread _ AHCI and the Thread _ sa device initialization Thread are equivalent to parallel operation, which driver completes the initialization first and starts to apply for a drive letter to the system, the system will allocate/dev/sda to the drive, and then the disk device which completes the initialization can only allocate/dev/sdb to the drive letter, so that the loading time of AHCI and the Raid/SAS driver is really determined to be the order of the drive letter. In the embodiment of the invention, the identification sequence of the disk is controlled by adjusting the loading sequence of the drive, and when the mode fails, the loading time interval of the two drives is increased by deleting the drive file in the mapping file, so that the stability of disk drive allocation is ensured by combining the two modes.
As can be seen from the description of the foregoing embodiment, the disk control method provided in the embodiment of the present invention includes determining a first drive module of a first disk and a second drive module of a second disk when a sequence of drive characters formed by a first drive character of the first disk and a second drive character of the second disk is inconsistent with a target sequence; adjusting the loading sequence of the first driving module and the second driving module according to the target sequence; the first drive module is used for driving a first disk arranged on the first interface, and the second drive module is used for driving a second disk arranged on the second interface. The embodiment of the invention ensures the identification sequence of the disk by adjusting the loading of the disk drive, thereby effectively ensuring the distribution stability of the disk drive characters of the disk and avoiding the disorder of the disk.
Through the above description of the method embodiments, those skilled in the art can clearly understand that the present invention can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium and includes instructions for causing a computer device (which may be a personal computer, a server, or a network device) to execute all or part of the steps of the methods according to the embodiments of the present invention.
