Referring to fig. 1, a software structure diagram of a Device Mapper architecture 11 of an electronic Device 100 according to an embodiment of the present disclosure is shown. The electronic Device 100 includes a Device Mapper architecture 11. The Device Mapper architecture 11 provides a mapping framework from logical devices to physical devices for the Linux kernel of the electronic Device 100, and a user can customize management policies of resources through the Device Mapper architecture 11. In this embodiment, a mapping Device (Device Mapper) is configured to map a Mapper Device, such as a logical Device, to one or more Target devices (Target devices). In this embodiment, the target device is a physical space segment mapped by the mapping device or a physical device mapped by the mapping device. Wherein each target device belongs to one type, and the I/O processing of different target devices is different. In this embodiment, logical Volume managers in the Linux kernel of the electronic Device 100, such as Linux Volume Manager 2 (LVM 2), enterprise Volume Management System (EVMS), dmroid, and the like, are implemented based on the Device Mapper architecture 11.

In this embodiment, the Device mapping criterion (DM-preference) is a mapping process for mapping a mapping Device to a target Device under the Device Mapper architecture 11, and the integrity of the Device or the Device partition is ensured by executing a DM-preference function on the mapping Device. Referring to fig. 1, the dm-nature includes two target devices, a Data Device (Data Device) and a Hash Device (Hash Device). And the data device is used for storing data and ensuring the integrity of the data. The hash device is used to store the hash value and verify the integrity of the data device.

In this embodiment, the mapping Device (i.e., mapper Device) and the Target Device (i.e., target Device) are in a one-to-one mapping relationship. The mapping includes that read operations to the mapping device are mapped to read operations to the target device. In the target Device, the DM-verify function maps the read operation to a read operation of a Data Device (Data Device), and adds a verify operation at the end of the read operation. The verification operation computes a hash value on the read data and compares the hash value with a value stored in a hash device. If the computed hash value is not the same as the value stored in the hash device, the check operation marks the read operation as an error.

In this embodiment, after the DM-verify function is turned on, the read-write capability (I/O performance) of the storage disk of the electronic device 100 is obviously reduced. In this embodiment, the storage disk refers to a storage partition of the electronic device 100, and for example, the storage disk may be an a disk, a B disk, a C disk, a D disk, and the like of the electronic device 100. In this embodiment, the storage disk is used to store programs and data, and all information in the electronic device 100, including the input raw data, the computer program, the intermediate operation result, and the final operation result, is stored in the storage disk. In the present embodiment, the storage disk includes a buffer (buffer memory). The buffer is a temporary memory for caching frequently used data in the storage disk to speed up the reading efficiency of the storage disk. For example, in a low memory condition of the electronic device 100, since the file data (page) to be read currently is not in the cache, the DM-verify function mostly performs a read operation (e.g., DM bufio read operation) in the cache. If the DM-verify function is turned on, the buffer _ new module finds that the requested buffer (buffer) has been swapped out and is not in the buffer of the DM buffer, and the buffer _ new module can only initiate a read request to the device, where the buffer _ new module is used to request to generate a buffer and control the buffer or the device to read data. Fig. 2 is a schematic diagram illustrating read data of the bufio _ new module according to an embodiment of the present application. The time for the bufio _ new module to read the device becomes completely dependent on the read-write speed of the device, and if the device performance is poor or garbage collection is performed, or more issued IO operations collected by the current device are queued in the queue of the device, the waiting time for the read operation becomes long. In order to avoid the waiting time of the read operation being too long, every preset time, for example, 30 seconds, the file system of the electronic device 100 checks whether the number of buffers (DM client buffers) of each client (client) that starts the DM-verify function or the remaining storage space exceeds the preset upper line of the buffer, if the number of buffers or the remaining storage space of the client that starts the DM-verify function exceeds the preset upper line of the buffer, the excess buffers that are not applied in the client are recycled, and if the number of buffers or the remaining storage space of the client that starts the DM-verify function does not exceed the preset upper line of the buffer, the client searches for the buffer that has exceeded the retention time limit D on the LRU (Least recent utilized) client to release the storage resources, so that the number of buffers or the remaining storage space of the client is kept below the upper line as much as possible. In this embodiment, the LRU clean list stores the least recently used buffer. In this embodiment, the pipeline refers to the usage amount of the cache, for example, the highest pipeline of the buffer of the client is 512 × 4096b (Byte), and the lowest reserved pipeline is 64 × 4096b. In an embodiment, the client's cache's water-line value is used to optimize the cache size of the buffer. In this embodiment, the upper-line value refers to an upper limit value of a buffer allocated to a storage disk or a buffer. In this embodiment, if the usage amount of the cache of the storage disk exceeds the upper-water line value of the cache, the file system may recycle the redundant cache that is not referenced in the storage disk. For example, if the water-line value of the storage disk a is 20M, but the available cache is 26M, the file system immediately reclaims the free 6M (26M-20M) in the storage disk a, and the 6M cache is used when the storage disk B has free services. In this embodiment, the lower horizontal value refers to a lower limit value of a buffer allocated to the storage disk or the buffer, that is, the lower horizontal value of the buffer is a buffer value that is least occupied under the condition that the storage function of the storage disk is ensured. For example: the lower waterline value of the storage disk A is 6M, the upper waterline value is 12M, namely the waterline range of the storage disk A is [6M,12M ], the lower waterline value of the storage disk B is 3M, the upper waterline value is 8M, namely the waterline range of the storage disk B is [3M,8M ], and the file system only has 10M available cache. If only the storage disk A has storage service at the beginning of the system file, the storage disk A occupies 10M of cache, and at the moment, the cache of the storage disk A is located in a [6M,12M ] section of the waterline range. If the storage disk B stores the service later, the file system allocates at least 3M of cache to the storage disk B because the lower pipeline value of the storage disk B is 3M, at this time, the total cache of the file system is 10M, the storage disk B occupies 3M, the storage disk a occupies 7M =10m-3M of cache, and the cache of the storage disk a is located in the waterline range or in the waterline range [6m,12m ].

In this embodiment, if the number of buffers or the remaining storage space of the client that starts the DM-verify function does not exceed the preset waterline of the buffers, the client searches for the buffer that is not used in the LRU clean list for the latest period of time and the longest period of time, and releases the storage resource.

In an embodiment of the present application, when all the storage disks in the electronic device 100 use the same waterline, if the waterline configuration is too high, the storage disks in the electronic device 100 with low use frequency cannot be recycled, which results in waste of storage resources; if the water line configuration is too low, the frequency of recycling the frequently used disk in the electronic device 100 is too fast, resulting in a reduction in the lifetime of the disk.

In order to solve the technical problem, the present application provides a method for setting a waterline of a storage disk. Referring to fig. 3, a flowchart of a method for setting a waterline of a storage disk in an embodiment of the present application is shown. The method specifically comprises the following steps.

In step S301, a process of executing the DM-verify function is detected.

Step S302, if a process for executing the DM-verify function is detected, obtaining the historical read-write data volume of the storage disk where the process is located, and determining a first coefficient and a first waterline increment value of the first coefficient according to the historical read-write data volume of the storage disk.

In this embodiment, the data amount of the history read and write of the process on the storage disk includes the data amount written to the storage disk and the data amount read from the storage disk. In this embodiment, the electronic device 100 determines the data amount of the historical read/write of the storage disk according to the data amount written into the storage disk and the data amount read from the storage disk, and searches the first relation table according to the data amount of the historical read/write of the storage disk to determine the first coefficient and the first waterline increment value. In this embodiment, the first relation table includes different data amounts of historical reading and writing, different first coefficients, and different first waterline increment values, and each data amount of historical reading and writing corresponds to one first coefficient and one first waterline increment value, and the electronic device 100 searches the first relation table according to the data amounts of historical reading and writing of the storage disk to determine the first coefficient and the first waterline increment value corresponding to the data amount of historical reading and writing. In this embodiment, the first coefficient is a usage coefficient of data size of historical read/write of the storage disk. The first coefficient is determined according to the use frequency of the storage disk, wherein the higher the use frequency of the storage disk is, the larger the first coefficient value is, and the use frequency of the storage disk is the data amount written into the storage disk and the data amount read from the storage disk. In this embodiment, the first waterline increment value is a unit value of an increase minimum storage amount or a buffer storage amount that is matched according to the data amount of the historical read/write of the storage disk. For example, in the first relation table, when the data amount of the historical read-write of the storage disk a is in the interval of 0G-2G, the corresponding first coefficient is 0.25, and the first waterline increment value is 2M; when the data amount of the history read-write of the storage disk A is within the interval of 2G-4G, the corresponding first coefficient is 0.35, and the first waterline increment value is 3M.

Step S303, determining a kernel for running the process, and determining a second coefficient and a second waterline increment value of the second coefficient according to the kernel.

In this embodiment, the second coefficient is a processing capability coefficient of a kernel that runs the process. In this embodiment, the cores are divided into a large core, a middle core and a small core according to processing capacity, where a processing rate or a processing frequency of the large core is higher than that of the middle core, and a processing rate or a processing frequency of the middle core is higher than that of the small core. In this embodiment, the value of the second coefficient is a ratio of a processing capacity (processing rate or processing frequency) of a kernel running the process to a processing capacity of the small kernel. For example, if the chip running the process in the electronic device 100 is a high-end chip, the second coefficient corresponding to the large core of the electronic device 100 is a ratio of the processing capability of the large core to the processing capability of the small core, and is, for example, 5:1, the second coefficient corresponding to the middle core of the electronic device 100 is a ratio of the processing capability of the middle core to the processing capability of the small core, and is, for example, 3:1, the second coefficient corresponding to the corelet of the electronic device 100 is 1:1. for another example, if the chip running the process in the electronic device 100 is a low-end chip, the second coefficient corresponding to the large core of the electronic device 100 is 3.5:1, the second coefficient corresponding to the kernel of the electronic device 100 is 2:1, the second coefficient corresponding to the corelet of the electronic device 100 is 1:1.

in this embodiment, the second pipeline increment value is a unit value of an increased minimum storage amount or a buffer amount that matches the processing capacity (processing rate or processing frequency) of the kernel that runs the process.

In this embodiment, the electronic device 100 finds the second relation table according to the kernel to determine the second coefficient and the second waterline increment value of the second coefficient. In this embodiment, the second relation table includes different kernels, different second coefficients, and different second waterline increment values, and each kernel corresponds to one second coefficient and one second waterline increment value. The electronic device 100 searches the second relation table according to the kernel running the process to determine a second coefficient and a second waterline increment value corresponding to the kernel. For example, in the second relation table, the second coefficient of the large core is 1, and the second waterline increment value of the large core is 5M; the second coefficient of the middle core is 3, and the second waterline increment value of the middle core is 3M; the second coefficient for the small kernel is 5 and the second waterline increment value for the medium kernel is 2M.

Step S304, calculating the waterline value of the storage disk according to the first coefficient, the first waterline increment value of the first coefficient, the second coefficient and the second waterline increment value of the second coefficient, and dynamically configuring the waterline value of the storage disk according to the calculated waterline value. For example, the calculated water line value is configured as a water line value of the storage disk.

In this embodiment, the waterline value of the storage disk is calculated according to a formula S = C × K + D × T, where C is a first coefficient, K is a first waterline increment value of the first coefficient, D is a second coefficient, T is a second waterline increment value of the second coefficient, and S is the waterline value of the storage disk. For example, if the first coefficient C is 0.25, the first waterline increment value K is 3M, the second coefficient D is 3, and the second waterline increment value is 3M, the waterline value calculated according to the formula S = C × K + D × T is S =0.25 × 3m +3 × 3m =9.75m.

In this embodiment, the water line values of the storage disk include an upper water line value and a lower water line value. In this embodiment, the first waterline increment value includes a first waterline increment value and a first waterline increment value. The second waterline increment value comprises a second waterline increment value and a second waterline increment value. The electronic device 100 searches the first relation table according to the historical read-write data volume of the storage disk to determine a first coefficient, a first upper waterline increment value and a first lower upper waterline increment value corresponding to the historical read-write data volume. The electronic device 100 searches the second relation table according to the kernel running the process to determine a second coefficient, a second waterline increment value and a second waterline increment value corresponding to the kernel. The electronic device 100 calculates the water-up line value of the storage disk according to a formula S1= C × K1+ D × T1, where K1 is a first water-up line increment value of a first coefficient, T1 is a second water-up line increment value of a second coefficient, and S1 is the water-up line value of the storage disk. The electronic device 100 calculates a lower waterline value of the storage disk according to a formula S2= C × K2+ D × T2, where K2 is a first waterline increment value of a first coefficient, T2 is a second waterline increment value of a second coefficient, and S2 is the lower waterline value of the storage disk. The electronic device 100 determines the waterline interval range of the storage disk according to the calculated water line value and the calculated water line value of the storage disk, and dynamically configures the waterline value of the storage disk according to the waterline interval range of the storage disk, for example, configures the waterline value of the storage disk in the waterline interval range.

In this embodiment, after the DM-verify function is turned on, the water line value of the storage disk is dynamically adjusted according to the data amount of the history read and write of the storage disk where the process executing the DM-verify function is located and the processing capability of the core running the process, so that the storage resource can be reasonably occupied and released, the problem that the storage disk with low use frequency cannot be recycled due to too high water line configuration and the problem that the storage resource is wasted due to too fast recovery of the storage disk with frequent use due to too low water line configuration and the problem that the service life of the storage disk is reduced due to too fast recovery of the storage disk with frequent use due to too low water line configuration is avoided.
