Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the 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 application.
At present, with the continuous expansion of the main program function, the memory dump file generated when the program is abnormal is also larger and larger, and the space for storing the memory dump file is limited, and we hope to analyze and locate the reason of the abnormality through the memory dump file as soon as possible when the main program plmain is abnormal. Therefore, the memory dump file generation scheme provided by the application can be used for rapidly storing the memory dump file in a limited storage space, can provide help for restarting the main program of the storage system, and improves the recovery efficiency of the main program of the storage system.
Referring to fig. 1, an embodiment of the present application discloses a method for generating a memory dump file, including:
s101, if the main program of the storage system quits running, the memory management module is used for inquiring a memory page with a disk falling mark in the system memory, and data in the memory page is determined to be data to be dumped.
It should be noted that, during the initialization phase of the main program of the storage system, the memory management module allocates a corresponding memory to each component in the main program. Each time a segment of memory is allocated, it will be determined whether marking of Harden (i.e. a landing mark) is required according to the purpose of the allocated memory. And when the memory dump file needs to be generated, determining whether the data in the corresponding memory page needs to be collected according to whether the memory page is Harden marked or not. In one embodiment, the method for querying a memory page with a landing mark in a system memory by using a memory management module includes: obtaining a memory page description table from a memory management module; and inquiring the memory pages with the falling disk marks in the system memory according to the memory page description table.
Generally, the exit of the main program of the storage system is triggered by an exception or a user instruction of the main program of the storage system. Therefore, in one embodiment, if an exception occurs in the main program of the storage system or a memory dump file generation instruction of the main program of the storage system is received, the main program of the storage system is controlled to exit from running.
S102, if the current residual space of the nonvolatile memory is larger than the size of the data to be dumped and the memory dump file in the nonvolatile memory is subjected to compression storage, creating an uncompressed memory dump file in which the data to be dumped are stored, and writing the uncompressed memory dump file into the nonvolatile memory.
In one embodiment, creating an uncompressed memory dump file storing data to be dumped comprises: and checking the data to be dumped, and if the data to be dumped passes the checking, writing the data to be dumped into an empty file to obtain an uncompressed memory dump file. Recording whether a mark, a dump type, the number of memory pages, file creation time, verification information and component information of a main program of a storage system are compressed into a file header of an uncompressed memory dump file. Wherein, LRC operation can be adopted to check the data to be dumped. The 8 memory pages constitute a iob (io buffer, io cache), one page is 4k in size, and one iob is 32k in size. Therefore, iob numbers can be recorded in the file header.
S103, if the main program of the storage system is restarted, compressing the uncompressed memory dump file in the nonvolatile memory.
In a specific embodiment, if the current remaining space is not larger than the size of the data to be dumped, it indicates that the current remaining space of the nonvolatile memory is too small to store the data to be dumped, so that the deletion operation is performed on the stored files in the nonvolatile memory according to the importance degree of the files; and if the current residual space is still not larger than the size of the data not to be dumped after the deletion operation is executed, generating a prompt message of insufficient space so that a user can manually clear the storage space of the nonvolatile memory. In order to avoid affecting the file generation efficiency, the number of times of executing the deletion operation may be limited, for example: the number of times the deletion operation is performed is limited to 1. The stored files in the nonvolatile memory may include other files (such as log files) in addition to the previously generated memory dump file. The importance degree of the file can be determined according to the creation date of the file, such as: the earlier the creation date is, the less important the file is, so that the file with the earlier creation date is deleted preferentially. Of course, the importance of the file may also be determined according to the priority of the file, for example: and preferentially deleting the files with low priority.
In one embodiment, if the current remaining space is larger than the size of the data to be dumped and there is an uncompressed memory dump file in the nonvolatile memory, it indicates that: although the current remaining space of the nonvolatile memory is enough to store the data to be dumped, the remaining space of the nonvolatile memory is not enough after the data to be dumped is stored, so that a compressed memory dump file storing the data to be dumped is created, and the compressed memory dump file is written into the nonvolatile memory to save the storage space of the nonvolatile memory. Among them, the uncompressed memory dump files are generally large.
It can be seen that, in this embodiment, after the main program of the storage system exits from running, the memory management module is used to query the memory page with the disk drop mark in the system memory to find the memory data related to the main program of the system, and then determine the data in the memory page as the data to be dumped; when the current residual space of the nonvolatile memory is larger than the size of the data to be dumped and the memory dump files in the nonvolatile memory are compressed and stored, creating an uncompressed memory dump file in which the data to be dumped are stored, and writing the uncompressed memory dump file into the nonvolatile memory, so that the memory dump files generated in different periods can be reserved, and the storage space of the nonvolatile memory can be saved; after the main program of the storage system is restarted, the uncompressed memory dump file in the nonvolatile memory is compressed, so that the memory dump file generated in each period is compressed and stored in the nonvolatile memory, the space can be saved, and the reduction of the file generation efficiency caused by compression operation can be avoided. Therefore, the memory dump file can be obtained by considering the limited storage space and the file generation efficiency, help can be provided for restarting the main program of the storage system, and the recovery efficiency of the main program of the storage system is improved.
The following embodiment provides a dump file generation apparatus including a cache unit, a nonvolatile storage unit, a trigger unit, a management unit, and a compression unit, and please refer to fig. 2 specifically.
Wherein, the buffer unit is: the internal memory directly exchanging data with CPU or MCU has the features of fast read/write speed and loss of power-off data, and may be memory of memory device or RAM.
Nonvolatile memory cell refers to: the module that the power failure data will not lose and can store the data for a long time can be a hard disk of the storage device, such as: solid state drives SSD, mechanical hard disk HDDs, and the like.
The trigger unit is used for triggering generation of the dump file, and is generally triggered when the main program of the storage system is abnormal or manually triggered by a user through a command.
When receiving the instruction of the trigger unit, the management unit stores the data in the cache unit to the nonvolatile storage unit in a compression or non-compression mode, or restores the memory dump file from the nonvolatile storage unit to the cache unit.
The compression unit is used for compressing the data in the cache unit or the uncompressed data in the nonvolatile memory.
Referring to fig. 3, a logic schematic of the device shown in fig. 2 for generating a dump file is shown in fig. 3, which specifically includes the following steps:
(1) The management unit starts, judges whether the number of the uncompressed memory dump files in the nonvolatile storage unit is more than 1, and when the number of the uncompressed memory dump files in the nonvolatile storage unit is more than 1, the management unit sequentially compresses the uncompressed memory dump files.
(2) The management unit circularly monitors whether the main program plmain of the storage system is abnormally interrupted or monitors whether a user manually triggers the generation of the memory dump file through the trigger unit, and if the main program plmain is abnormally interrupted or a memory dump file generation instruction is monitored, the management unit controls the main program plmain to exit.
(3) The management unit obtains memory page information of the cache unit, which needs to be dumped by the main process pipeline, through the memory management module.
(4) The management unit calculates the size of the dump file to be stored currently according to the memory page information to be dumped, judges whether the residual space of the nonvolatile storage unit is larger than the size of the current dump file, deletes a part of files in the nonvolatile storage unit according to the importance of the files if the residual space is smaller than the size of the dump file, and enters the step (5); otherwise, it indicates that the nonvolatile memory cell space is sufficient, and step (6) is entered.
(5) And the management unit judges whether the residual space of the nonvolatile storage unit is larger than the dump file size again, and if the residual space is not enough, the management unit reports an alarm to prompt a user.
(6) The management unit judges whether the non-volatile storage unit has an uncompressed dump file, if so, the management unit controls the generation of the compressed dump file, and the step (7) is carried out; otherwise, the control generates an uncompressed dump file, and the step (8) is carried out.
(7) Creating a compressed dump file: and taking the verified memory page information of the cache unit as a file header, compressing the memory page data to be dumped to obtain compressed data B, and writing the compressed data B into the file to obtain a compressed dump file.
(8) Creating an uncompressed dump file: and taking the verified memory page information of the cache unit as a file header, then directly writing the memory page data to be dumped into the file, and obtaining the uncompressed dump file after the writing is finished.
(9) The management unit controls the starting of the main program plmain process. After the main program plmain process is started, whether uncompressed dump files exist in the nonvolatile storage unit is judged, if yes, the main program plmain is informed to compress the uncompressed dump files in an inter-process communication IPC mode, then the step (2) is carried out, and if not, the step (2) is directly carried out.
Therefore, the memory information is compressed, the memory dumping efficiency of the storage system can be improved, and the occupation of the hard disk space of the storage device system is reduced. Meanwhile, whether the file is compressed or not can be selectively determined when the file is generated every time, so that the limited storage space and the file generation efficiency can be considered, the recovery efficiency of the main program of the storage system is improved, and effective support is provided for storage equipment fault location and research and development personnel to analyze and solve the problems.
