Description
Technical Field
The invention belongs to the field of computers, and particularly relates to a method, a system, equipment and a medium for verifying the correctness of a hard disk write-in point.
Background
With the development of technologies such as internet, cloud computing, internet of things and the like, solid state disks are widely used as a new generation of storage. However, a new generation of ZNS (partitioned Namespace) SSD realizes a leap-forward in performance, capacity, lifetime, cost, usability, etc., and becomes a new development direction of solid state disk. SSDs using ZNS do not need to be over-configured as traditional enterprise SSDs. The ZNS SSD is also responsible for performing wear leveling, but no longer needs to provide a large spare area for the garbage collection process. With proper use, ZNS allows host software to avoid almost all cases of SSD internal Write Amplification (WA). Enterprise-level SSDs typically use an over-provisioning ratio of up to 28% (800 GB available per 1024GB of flash memory on a typical 3DWPD model), while ZNS SSDs can expose almost all of the capacity to the host system without impacting the ability to have high sustained write performance. The ZNS SSD still needs some spare capacity (e.g. to cope with sudden failures when the flash memory is exhausted), and further in some cases ZNS can be reduced by about 10 times in overload ratio.
In the ZNS specification, the entire LBA (logical block address) range of the SSD namespace is divided into a plurality of equal-length zones, each equal-length LBA Zone becomes a Zone, data must be written in each Zone in a sequential manner, and the position where data starts to be written is not arbitrary, so as to avoid the phenomenon of data random writing such as overwriting, the ZNS specification strictly defines the position where data starts to be written, that is, Write Pointer, abbreviated as WP, and in order to ensure the correctness of data writing, we need to further verify the WP defined by the ZNS specification to ensure the correctness of the data writing.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
ZNS storage technology is developed from OC (Open Channel) SSD, and realizes that FTL (Flash Translation Layer) is migrated from the inside of SSD to Host end of upper Layer, and the inside of SSD is opened to the Host end, so that users can flexibly own specific FTL according to own needs, and the cost is that software architecture must be redesigned, the cost is very high, and the requirement on technical strength of users is also very high.
The ZNS is a structure that the whole storage space of the solid state disk is equally divided into a plurality of partitions with the same size, that is, a zone, each zone partition includes a plurality of logical blocks, each logical block corresponds to one logical block address, that is, an LBA, but unlike the conventional SSD storage technology, the ZNS directly interfaces the solid state disk to an operating system or an application program on an upper layer through the LBA, so that in order to facilitate the use of an upper layer application, only the LBA is used as a data storage and index structure interfacing with the upper layer application. In this implementation, the storage space can be directly provided to the application program, and the application program exclusively uses the space allocated to the application program, as shown in fig. 2, the left side of fig. 2 is a conventional solid state control structure, the application program (which broadly includes an operating system) needs to store corresponding data through a controller of the SSD, and the conventional implementation cannot determine the location where the data is stored by the application program, and the data is stored through a management mechanism implemented by the SSD controller when the data is written into the SSD, that is, if a certain application program on the computer writes data into the SSD, the written data is written into different areas according to a scheduling policy of the SSD controller according to a time relationship. In contrast, the ZNS SSD, as shown on the right side of fig. 2, may be divided into fixed storage areas, for example, the application 2 has the right to use the storage space in the middle dotted line.
However, due to the requirement of sequential writing in a zone, when the same zone is written in multiple threads, the writing speed is limited or the writing position is incorrect due to competition of writing pointers between threads, and therefore, the correctness check of the writing pointers of the corresponding zones is required.
As shown in fig. 1, to solve the above problems, the present invention provides a method for verifying correctness of a hard disk write point, including:
step S1, determining a write-in point of the storage partition through the storage partition, and determining a test interval of the storage partition based on the write-in point;
step S1, performing write test on the logic block in the test interval, and judging whether the logic address of the logic block successfully subjected to the write test is the same as the logic address of the write-in point;
and step S2, in response to that the logical address of the logical block which is successfully written in the test is the same as the logical address of the writing point, determining the writing point of the storage partition as abnormal.
In the embodiment of the present invention, in step S1, the storage partition refers to a zone partition in the ZNS SSD, and since there is one write point per zone partition, the zone partition may be referred to as a test partition for its write point test. The write point refers to a write point of the zone partition, and as described above, due to the characteristics of the ZNS SSD, data of the zone partition is written in a sequential manner, and when the data is written into the zone partition, the corresponding write point needs to be acquired.
Further, in the present invention, the test interval refers to a plurality of LBA address ranges including the write point. The logical block refers to the smallest unit of storage in a zone partition, and each unit of storage corresponds to one logical block address, namely LBA. After the corresponding write point needing to be verified is obtained, an address space in a certain range before and after the write point is used as a test interval. If the LBA address of the write point is 21, several LBA addresses before and after 21 are used as a test space, that is, a range from LBA addresses 15 to 26 may be used as a test interval.
In step S2, traverse the LBA addresses in the test interval, and write data to the LBA addresses in the test interval, and if the write is successful, determine whether the LBA addresses that are successfully written are the same as the logical address of the write point.
If the LBA address of the write-in point is different from the LBA address written successfully, according to the specification of the ZNS SSD, a plurality of write-in points exist in a zone partition, namely, a write-in point error exists. According to the mechanism of the ZNS SSD, after an error write point is used as a start address of write data, the phenomenon of abnormal write data can be caused. There is some data that will be overwritten.
In some embodiments of the present invention, determining the test interval of the memory partition based on the write point comprises:
and determining the test interval according to the type and the size of the storage partition and/or the adjacent storage partition based on the write-in point.
In some embodiments of the invention, determining the test interval according to the type of the memory partition and/or the neighboring memory partition and the size thereof comprises:
and determining the logical block address of the writing point of the storage partition, and moving the logical block address forwards and backwards by corresponding distances according to the size of the storage partition to be used as a test interval.
In the present embodiment, the range of the test interval is selected to be determined according to the size of the test zone partition and the type of the adjacent zone partition.
In the ZNS SSD, there are 3 types of zone partitions related to correctness of writing points, one empty type that the whole zone partition is empty, one openend type that partial data is stored in the partition, and the other full type that the data in the partition is stored enough data and cannot store other data. Thus, in some embodiments of the invention, the size of the test interval is set according to the number of logical blocks of the test partition, i.e. if the tested zone partition has 10 logical blocks and the LBA address is [21,30], the test interval may be the entire zone partition, i.e. [21,30 ]. If the write point of the zone is 21, the test interval may be [11,30 ].
In some embodiments of the present invention, if the type of the partition to be tested is empty, its write point is the first logical block of the partition, and if its neighboring partition is also empty, assuming that the partition size is 10, the interval of the test partition is [21,30], and the address space of the previous partition is [11,20], then the test interval is an interval of 10 LBA sizes around the write point 21, i.e., [11, 21,30 ].
In some embodiments of the present invention, determining the test interval according to the type of the memory partition and/or the neighboring memory partition and the size thereof further comprises:
and acquiring the write-in points of adjacent partitions, and taking the logic block address of the write-in points of the adjacent partitions as the test interval.
In this embodiment, if the test partition is of an opened type, the write point of the test partition is within a certain address space range in the zone partition. At this time, if the partition types of the adjacent partitions are all opened, the addresses of the write points of the two adjacent partitions may be used as the test interval of the test partition for the test interval of the test partition.
Specifically, if the write point of the test partition is 26(LBA address, the same below), the write point of the previous zone is 15, and the write point of the next zone is 33, the test interval of the test partition may be [15,32], and data is written into the address space of [15,32], and if the logical blocks in the test interval are all normal, data is written into the logical block with the LBA address of 26 successfully, but data cannot be written into other LBA addresses.
In some embodiments of the present invention, when the test interval is traversed to perform the write data test, the write point of the test partition needs to be skipped, and finally, the write point is subjected to the write data test.
In some embodiments of the present invention, determining the test interval according to the type of the memory partition and/or the neighboring memory partition and the size thereof further comprises:
and acquiring a write-in point and a boundary of adjacent partitions, and taking the logic block address of the write-in point and the boundary as the test interval.
In this embodiment, a write point of a partition of adjacent partitions and a boundary of another partition are used as test intervals. Specifically, if the type of the left zone partition of the test partition is an opened partition and the right partition is an empty partition, the write point of the partition on the left side of the test partition (sorted in the order of LBA addresses) may be the start address, and the entire partition on the right side of the test partition may be the test interval.
Correspondingly, if the left side of the test partition is empty partition or full partition, and the right side is opened partition, the boundary of the partition on the left side, i.e. the write point, is used as the start address of the test interval, and the write point of the partition on the right side is used as the end address of the test interval.
In some embodiments of the present invention, performing a write test on the logic block in the test interval, and determining whether the logic block successfully subjected to the write test is the same as the logic address of the write point includes:
traversing all the logic block addresses in the test interval, and writing data into the logic block addresses;
and receiving a result of writing data into the logic block address, and judging whether the logic block address of the successfully written data is the same as the logic block address of the writing point of the storage partition.
In this embodiment, as described above, traversing all the logical addresses in the test interval, writing data to each logical address, and receiving corresponding write feedback, if the write is successful, determining whether the write address is the same as the corresponding write point, and if the write successful LBA address is the same as the write point, it indicates that the write point is normal, and if the write successful LBA address is different from the write point LBA address, it indicates that an LBA address with a write point error exists in the test interval, and immediately processes the data of the test partition or masks the partition.
In some embodiments of the invention, the method further comprises:
and receiving a result of writing data into the logical block address, and judging whether the logical block address of the write-in point of the adjacent storage partition is the same as the logical block address of the write-in point of the adjacent storage partition.
In this embodiment, if the test interval covers multiple zone partitions, it is determined whether the LBA address where the write test is successful in the test interval is the same as the address of the write point of the zone partition covered, and the LBA address where the write test is successful is compared with the write point of the adjacent partition. If the data is the same, the successful writing point of the written data is correct. The difference indicates that a write point error exists in the zone partition corresponding to the LBA address.
The correctness verification method for the hard disk write-in point respectively verifies the correctness of WP corresponding to Zone in writable state and WP corresponding to Zone in non-writable state, thereby verifying the correctness of WP and ensuring the correctness and safety of data write-in.
