Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the present invention, it should be noted that the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
The embodiment of the invention discloses a hard disk adaptation method which can be applied to ZNS SSDs, wherein the ZNS SSD can be configured in terminal equipment such as a computer, when the kernel of an operating system of the terminal equipment is changed or upgraded, the identification requirement on the ZNS SSD can be changed, the terminal operating system is not limited, and the method can be any operating system with limitation on the size of a zone in the identification of the ZNS SSD. For convenience in describing the technical solutions described in the embodiments of the present application, in the following embodiments, the current operating system uses 5.10 and above version of linux as an example, and the 5.10 and above version of linux kernel requires that the zone size of each zone must be the power of 2 n in the process of identifying the ZNS SSD. As shown in fig. 1, the method comprises the steps of:
For example, the acquisition opportunity of the ZNS SSD to the adaptive requirement of the current operating system may be that the ZNS SSD does not write data for a certain period of time, and the reason why the ZNS SSD does not write data for a certain period of time may be that the current operating system does not recognize the ZNS SSD, where the ZNS SSD may respond to the operation of acquiring the adaptive requirement of the current operating system to itself; the acquisition time of the adaptation requirement of the ZNS SSD on the current operating system can also be the operation of the ZNS SSD on the response of the current operating system to the adaptation requirement according to the fixed preset interval duration. The embodiment of the application does not limit the certain duration, the preset interval duration and the acquisition time of the ZNS SSD for the adaptation requirement of the current operating system, and the person skilled in the art can determine the acquisition time according to actual needs. The method for acquiring the adaptation requirement of the current operating system to the ZNS SSD can be that the type of the current operating system is determined, and the adaptation requirement of the type of operating system to the ZNS SSD is acquired from a network in a networking mode according to the type of the current operating system.
As an optional embodiment of the present invention, step 101 of obtaining the adaptation requirement of the current operating system to the ZNS SSD includes: acquiring the type of a current operating system; and determining the adaptation requirement of the ZNS SSD according to the type of the current operating system. The method includes the steps of obtaining an information table for storing attribute information of a current operating system, inquiring type bit data representing the current operating system from the information table, analyzing the type bit data to obtain the type of the current operating system, and matching from a database pre-stored with corresponding type adaptation requirements according to the type to obtain the adaptation requirements of the current operating system to the ZNS SSD. If the current system is determined to be a linux operating system with the version of 5.10 and above, the identification requirement of the operating system on the ZNS SSD can be determined according to the type or the configuration condition of the operating system.
Illustratively, the manner in which the ZNS SSD makes a maximum storage space for each zone itself may determine the maximum storage space for each zone by identifying and reading the number of super blocks contained in each zone and the storage space data for each super block; if the memory size of one super block is 360M, then the maximum memory size of one zone is 1440M for a zone containing 4 super blocks. The determination of the memory size of each superblock may be determined by reading the attribute data of the corresponding superblock.
As an optional embodiment of the present invention, determining the maximum storage space of each zone included in the ZNS SSD in step 102 may further include: acquiring attribute data of the ZNS SSD; and determining the maximum storage space of each zone contained in the ZNS SSD according to the attribute data. For example, the attribute data of the ZNS SSD includes attribute data of a specific maximum storage space of each zone, and the maximum storage space of each zone included in the ZNS SSD may be obtained by reading the corresponding attribute data and analyzing.
For example, it may be determined whether the maximum storage space of each zone in the current ZNS SSD meets the identification requirement of the current operating system according to the obtained adaptation requirement. For example, as the linux kernel of version 5.10 and above requires that the zone size of each zone must be the size of the nth power of 2 in the process of identifying the ZNS SSD, when the maximum storage space of any zone in the ZNS SSD does not meet the requirement of the current operating system on the adaptation of the ZNS SSD, the corresponding zone in the ZNS SSD is subjected to capacity expansion processing, so that the maximum storage space of each zone in the expanded ZNS SSD meets the identification and call of the current operating system; for example, if the maximum storage space of each zone in the current ZNS SSD hard disk is 1440M and the requirement of the current operating system linux on the zone size of each zone is the nth power of 2, the zone size of the zone which does not meet the identification requirement can be expanded from 1440M to 2G or 4G by expansion, so that the identification and use of the current linux operating system on the ZNS SSD are met;
in addition, the identification requirement of the linux is met by performing capacity expansion processing (such as capacity expansion to 2G or 4G) on the storage space of the zone which does not meet the adaptation requirement of the linux of the operating system, and compared with the mode of performing capacity reduction processing, such as capacity reduction of the zone size to 1G, the method provided by the embodiment of the invention adopts the capacity expansion processing mode so that the original zone size of the corresponding zone after the capacity expansion processing is not wasted; that is, if the adaptation requirement of linux is to be met, a zone size of 1G is selected, and when the original storage space of the zone is 1440M, each zone wastes (1440M-1G) storage space although the adaptation requirement of linux is met after the volume reduction processing, so that a large amount of storage space in the ZNS SSD is wasted. Meanwhile, in order to avoid excessive capacity expansion, the maximum storage space of the corresponding zone can be expanded to the minimum capacity expansion configuration under the condition of meeting the identification requirement according to the current zone size, for example, when the zone size is 1440M, the capacity expansion is preferably carried out to 2G under a linux operating system.
As an optional embodiment of the present invention, after expanding the maximum storage space of the corresponding zone in the ZNS SSD according to the adaptation requirement in step 103, the hardware adaptation method further includes: 104, determining a zone increased storage space for capacity expansion processing; step 105, configuring the zone increased storage space subjected to the capacity expansion processing as an invalid storage space, and configuring the original storage space not subjected to the capacity expansion processing as an effective storage space.
By way of example, the storage space increased by the expanded zone may be determined by comparing the size of the storage space before and after expansion by expanding the corresponding zone. If the memory space of any zone is expanded to 2G, the increased memory space is (2G-1440M) =608M compared to the zone with 1440M as the original memory space. Configuring the increased storage space as invalid storage space, and configuring the original zone size of each zone as valid storage space; by fixing the available storage space of the zone before and after capacity expansion, the storage space which is expanded for matching with the operation system identification during the upgrading or changing of the operation system cannot influence the normal use of the user, namely the storage space which is expanded for matching with the operation system identification in the system cannot be perceived by the user, and then the problem of the user on the change of the storage space of the ZNS SSD of the existing terminal cannot be caused, so that the user keeps inherent cognition on the size of the storage space of the terminal, and the normal storage use of the user in the terminal is ensured. That is, when the operating system calls, the size of the storage space actually reported to the operating system is 2g×n, and the size of the zone capacity available to the actual user is 1440m×n, where n is the maximum zone number of the ZNS SSD.
As an optional embodiment of the invention, the hardware adaptation method further comprises: when a data storage instruction of a user is received, the received data to be stored is stored in the original storage space of the current zone.
By storing the received data to be stored in the original storage space of the current zone, the newly added storage space in the zone can not influence the historical storage cognition and habit of the user, namely, the storage space which is expanded for matching with the identification of the operating system in the system can not be perceived by the user, so that the user can not question the change of the storage space of the existing terminal, the inherent cognition of the user on the storage space of the terminal is ensured, and the normal storage and use of the user in the terminal are ensured.
As an optional embodiment of the invention, the hardware adaptation method further comprises: determining the size of a storage space required by the received data to be stored; when the size of the storage space required by the received data to be stored exceeds the size of the remaining storage space in the original storage space of the current zone, responding to feedback of prompt information of data writing failure to a user.
The method for determining the storage space required by the data to be stored can be implemented by inquiring and counting the number of bytes of the received data to be stored, and determining the storage space required by the data to be stored according to the inquiry and counting results. And identifying the original storage space of the current zone, and if the size of the storage space required by the received data to be stored exceeds the size of the remaining storage space in the original storage space of the current zone, feeding back prompt information of data writing failure to a user, so that the user stores the data to be stored by using other zones, and the reliable storage of the data to be stored of the user is ensured.
As an optional embodiment of the invention, the hardware adaptation method further comprises: and when a space capacity query request of a user is received, feeding back the maximum storage space size of the ZNS SSD before capacity expansion to the user. The maximum storage space size of the ZNS SSD before capacity expansion is fed back to the user according to the received space capacity query request of the user, so that the inherent cognition of the user on the storage space contained in the ZNS SSD configured in the terminal equipment is ensured, the data stored to the terminal is reasonably allocated, and the normal data storage process of the user is not influenced by the expanded storage space for meeting the identification requirement of the current operating system on the ZNS SSD.
