Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present invention.
The invention provides a memory fault processing method, a device, equipment and a medium, which aim to solve the problem that a server cannot be started normally due to memory faults when the server performs memory isolation.
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
Currently, although the main stream servers are mainly Intel x86 architecture series, development of Intel x86 architecture servers has been stopped in recent years. Because of the need of the development of the era, the update speed of the server device is increased, and a new form of server architecture is urgently needed at present, so that the server of the ARM architecture is generated.
In recent years, servers of ARM architecture have evolved dramatically. But the ARM architecture server has a certain gap relative to the ecological environment of the mature Intel x86 server. For example, when a server of the ARM architecture uses a memory isolation technique similar to the Intel x86 server (the memory isolation technique is a security mechanism that makes the system more secure and reliable in operation by isolating the memory spaces of different processes or users), a failed memory Training (i.e., a memory failure condition) may occur, which may cause the server to fail to start. Therefore, in order to solve the above-mentioned problems, the present invention provides a memory failure processing method, which aims to solve the problem that a server cannot be started normally due to a memory failure when the server performs memory isolation. It can be understood that the method provided by the invention is mainly applied to servers, particularly servers using memory isolation technology, including but not limited to ARM servers using memory isolation technology.
Fig. 1 is a flowchart of a memory failure processing method according to an embodiment of the present invention. As shown in fig. 1, the method includes:
s10: and when the server detects that the memory fault exists after the power-on, acquiring the whole memory information of all the memories in the server.
The overall memory information includes the total memory quantity and total capacity.
Specifically, when a server (for example, FT2000+ server) of an ARM architecture using a memory isolation technique is powered on and booted, the server detects whether a memory failure occurs in itself, i.e., determines whether a memory failure occurs. And when the server detects that the memory fault exists after the power-on, acquiring the whole memory information of all the memories in the server.
It is understood that there are typically multiple memory banks in the server, and the capacity of each memory may be the same size or different sizes. And acquiring the overall memory information of all the memories in the server, namely taking all the memories as a whole, and acquiring the memory information of the whole memory. The overall memory information includes the total memory quantity and total capacity. It should be noted that the total capacity of the total memory is the sum of the capacities of the memories in the server.
S11: and acquiring fault memory information of the fault memory in the server.
The fault memory information comprises the number of the fault memories and the capacity of the fault memories.
It will be appreciated that when the server detects a memory failure condition, the failed memory can be located. Further, it is necessary to obtain failure memory information of the failure memory in the server. The fault memory information comprises the number of the fault memories and the capacity of the fault memories.
It should be noted that the number of the fault memories may be one or more, which is not limited in this embodiment, and depends on the specific implementation. Therefore, when the number of the fault memories is plural, in the obtained fault memory information, the capacity of the fault memory is specifically the sum of the capacities of the fault memories.
S12: judging whether the fault memory information meets preset conditions according to the overall memory information; if not, the process proceeds to step S13. If yes, the process proceeds to step S14.
S13: and skipping the operation fault memory, and initializing the rest memories according to the current memory initialization logic so as to restart the server.
S14: the server is restarted.
After the overall memory information of all memories of the server and the fault memory information of the fault memory are respectively obtained, judging whether the fault memory information meets preset conditions or not according to the overall memory information. It can be understood that the preset condition in this embodiment is used as a criterion to determine the specific influence condition of the fault memory on the server start. In this embodiment, the preset conditions are not limited, and specific condition limits may be set according to the number of memories, and specific condition limits may also be set according to the memory capacity, which is determined according to specific implementation situations.
When the fault memory information is confirmed to not meet the preset condition according to the whole memory information, the fault memory is considered to have larger influence on the server, the fault memory is skipped to operate at the moment, other memories are initialized according to the current memory initialization logic, so that the server is restarted, and the normal starting of the server is completed. And when the fault memory information is confirmed to meet the preset condition according to the whole memory information, the influence of the fault memory is considered to be smaller, and the server can be directly restarted.
In this embodiment, when a memory failure is detected after a server is powered on, overall memory information of all memories in the server is obtained; the overall memory information comprises the number and the total capacity of all memories; acquiring fault memory information of a fault memory in a server; the fault memory information comprises the number of the fault memories and the capacity of the fault memories; judging whether the fault memory information meets preset conditions according to the overall memory information; if not, skipping the operation fault memory, and initializing the rest memories according to the current memory initialization logic to restart the server. Therefore, when the server detects the memory fault, the scheme determines the influence condition of the fault memory on the starting of the server by acquiring the whole memory information of all memories in the server and the fault memory information of the fault memory and taking the preset condition as a reference; specifically, when the preset condition is not met, the fault memory is skipped to run, so that the influence on the running of the server is avoided, the server can be restarted normally, and the problem that the server cannot be started normally due to the memory fault when the memory isolation is executed by the server is solved.
In order to determine whether the failure memory information of the failure memory meets the preset condition, based on the foregoing embodiment, as a preferred embodiment, determining whether the failure memory information meets the preset condition according to the overall memory information includes:
s120: judging whether the ratio of the number of the fault memories to the number of all memories is not greater than a first threshold value, and the ratio of the capacity of the fault memories to the capacity of all memories is not greater than a second threshold value; if not, the preset condition is not satisfied, and the process proceeds to step S13.
In a specific implementation, the number and the total capacity of all memories and the number and the capacity of the fault memories are compared correspondingly. Specifically, whether the ratio of the number of the failed memories to the number of the total memories is not greater than a first threshold value or not is judged, and the ratio of the capacity of the failed memories to the capacity of the total memories is not greater than a second threshold value. It should be noted that, in this embodiment, the first threshold value and the second threshold value are not limited, and depend on the specific implementation. Further, since the first threshold is a number of thresholds and the second threshold is a capacity threshold, there is no size relationship between the first threshold and the second threshold.
When it is determined that the ratio of the number of the failed memories to the number of the total memories is greater than the first threshold, or it is determined that the ratio of the number of the failed memories to the number of the total memories is greater than the second threshold, or it is determined that the ratio of the number of the failed memories to the number of the total memories is greater than the first threshold and the ratio of the number of the failed memories to the number of the total memories is greater than the second threshold, the preset condition is not satisfied, and at this time, the failed memories have a greater influence on the server, and step S13 is required to be entered to skip the failed memories.
In this embodiment, based on the corresponding comparison of the number and the total capacity of all the memories and the number and the capacity of the failed memories, the judgment of whether the failed memory information meets the preset condition is implemented, and the accuracy of the judgment is improved.
When the failed memory is skipped, the remaining memory is initialized using the current memory initialization logic, but the failed memory is skipped, its memory capacity is also counted as the overall system capacity. If the allocation of the system capacity according to the original initialization logic cannot meet the same project deployment, a problem occurs in the server memory deployment, so that the system capacity needs to be further reallocated. Specifically, based on the above embodiment, as a preferred embodiment, after skipping the operation failure memory and initializing the rest of the memories according to the current memory initialization logic, the method further includes:
s15: and acquiring the capacity of other memories according to the total capacity of all memories and the capacity of the fault memory.
The other memories are memories except the fault memory in all memories.
S16: and acquiring the system capacity of the server according to the quantity of the other memories and the capacity of the other memories.
S17: the system capacity of the server is allocated to the system of the server.
In a specific implementation, the capacity of other memories is obtained according to the total capacity of all memories and the capacity of the fault memory. It is understood that the other memories are memories except for the fault memory in the whole memories, and the capacity of the other memories is the capacity of each remaining usable memory in the whole memories. And obtaining the total sum of the residual memory capacities which can be used currently according to the quantity of other memories and the capacities of other memories, dividing the total sum of the residual memory capacities to enable the server to meet the system capacity under the same project deployment, and finally distributing the system capacity to the system of the server so as to meet the requirement of unified deployment of the system as far as possible.
In this embodiment, the system capacity of the server is further obtained by obtaining the capacities of other memories according to the total capacity of all memories and the capacities of the failed memories, and the system capacity of the server is distributed to the system of the server, so as to meet the requirement of uniform deployment of the server system.
In order to achieve higher performance of the server memory, the method further includes, as a preferred embodiment, on the basis of the foregoing embodiment:
s18: judging whether the ratio of the number of the fault memories to the number of all memories is not greater than a third threshold value, and the ratio of the capacity of the fault memories to the capacity of all memories is not greater than a fourth threshold value; if yes, the process proceeds to step S19.
S19: the current memory initialization logic is changed.
Wherein the third threshold is less than the first threshold and the fourth threshold is less than the second threshold.
In a specific implementation, it is determined whether a ratio of the number of failed memories to the number of all memories is not greater than a third threshold, and a ratio of a capacity of the failed memories to a capacity of all memories is not greater than a fourth threshold. In this embodiment, the third threshold and the fourth threshold are not limited, and they are determined according to specific implementation cases. Since the third threshold is a number threshold and the fourth threshold is a capacity threshold, there is no size relationship between the third threshold and the fourth threshold. It should be noted that the third threshold is smaller than the first threshold and the fourth threshold is smaller than the second threshold.
When the ratio of the number of the fault memories to the number of all memories is not greater than the third threshold value and the ratio of the capacity of the fault memories to the capacity of all memories is not greater than the fourth threshold value, the fault memories are considered to have smaller influence on the server at the moment, and the current memory initialization logic can be changed, so that the performance of the server memories reaches higher service performance.
In implementations, changing the memory initialization logic may cause some problems with a small probability. For example, after a server reboot, the memory capacity available to the server system is inconsistent with the memory capacity last started by the server, which may result in failure of the server performance test or other tests to meet the memory capacity requirements. To avoid this problem, based on the above embodiment, as a preferred embodiment, after changing the current memory initialization logic, the method further includes:
S20: and acquiring the memory capacity distribution ratio of the server before restarting.
S21: the control server is restarted.
S22: and obtaining the memory capacity distribution ratio after restarting the server.
S23: judging whether the memory capacity distribution ratio after restarting the server is not more than the memory capacity distribution ratio before restarting the server; if yes, go to step S24; if not, the process proceeds to step S27.
S24: and performing memory virtual expansion on the capacity of each memory.
S25: and performing over-frequency processing on the central processing unit of the server.
S26: and allocating the capacity of each memory after the virtual expansion of the memory according to the memory capacity allocation ratio before restarting the server.
S27: and performing capacity deployment and regulation on the system capacity of the server according to the memory capacity distribution ratio after restarting the server.
Firstly, the memory capacity allocation ratio of the server before restarting is obtained through the firmware of a basic input output system (Basic Input Output System, BIOS) of the server. And restarting the control server, and recording the memory capacity allocation ratio after restarting the server. And further taking the restarted memory capacity distribution condition as a base point, and judging whether the memory capacity distribution ratio after restarting the server is not larger than the memory capacity distribution ratio before restarting the server.
If the memory capacity allocation ratio after restarting the server is not greater than the memory capacity allocation ratio before restarting the server, in order to meet the requirement of the lack of memory capacity, virtual memory expansion is needed for each memory capacity, and simultaneously, over-frequency processing is performed for a central processing unit of the server so as to adapt to the virtual memory expansion. And finally, allocating the capacity of each memory after virtual expansion of the memory according to the memory capacity allocation ratio before restarting of the server so as to maintain a reasonable memory allocation ratio.
If the memory capacity allocation ratio after restarting of the server is confirmed to be larger than the memory capacity allocation ratio before restarting of the server, in order to keep consistency of the memory capacity allocation ratios before and after restarting, the memory capacity allocation ratio after restarting of the server needs to be counted, and overall capacity deployment and regulation are carried out on the system capacity of the server according to the memory capacity allocation ratio after restarting of the server.
In this embodiment, by recording the memory allocation ratio before and after restarting the server, different memory allocation modes are adopted according to the size of the two, so as to meet the requirements of server performance test or other tests on memory capacity.
In order to prompt the server and the user when the operation of the server is seriously affected by the failed memory, the method further comprises, based on the above embodiment, as a preferred embodiment:
S28: judging whether the ratio of the number of the fault memories to the number of all memories is not greater than a fifth threshold value, and the ratio of the capacity of the fault memories to the capacity of all memories is not greater than a sixth threshold value; if not, the process proceeds to step S29.
S29: confirming that the fault memory duty ratio exceeds the limit, and sending a prompt signal to a baseboard management controller of the server.
Wherein the fifth threshold is greater than the first threshold and the sixth threshold is greater than the second threshold.
In a specific implementation, it is determined whether a ratio of the number of failed memories to the number of all memories is not greater than a fifth threshold, and a ratio of a capacity of the failed memories to a capacity of all memories is not greater than a sixth threshold. In this embodiment, the fifth threshold and the sixth threshold are not limited, and they are determined according to the specific implementation. Since the fifth threshold is a number of thresholds and the sixth threshold is a capacity threshold, there is no size relationship between the fifth threshold and the sixth threshold. It should be noted that the fifth threshold is greater than the first threshold and the sixth threshold is greater than the second threshold.
If the ratio of the number of the fault memories to the number of the all memories is greater than the fifth threshold, or the ratio of the capacity of the fault memories to the capacity of the all memories is greater than the sixth threshold, or the ratio of the number of the fault memories to the number of the all memories is greater than the fifth threshold and the ratio of the capacity of the fault memories to the capacity of the all memories is greater than the sixth threshold, the ratio of the fault memories is considered to be over-limited, the operation of the server is seriously affected, and the operation ecology of the server cannot be matched. At this time, a prompt signal needs to be sent to a baseboard management controller (Baseboard Management Controller, BMC) of the server, so that the system and a user can acquire the memory fault condition, remind the user of having to replace the fault memory, and avoid the greater influence caused by the fault memory.
In addition, in order to enable the user to acquire the server restart and the related information thereof in time, on the basis of the above embodiment, as a preferred embodiment, after restarting the server, the method further includes:
s30: and outputting information of successful restarting of the server.
S31: the running log of the server is updated to record the cause of the server restart.
Specifically, after restarting the server, outputting information that the server is restarted successfully. In this embodiment, the specific form of the output information is not limited, and may be audio prompt information or light prompt information, according to specific implementation conditions. The running log of the server is further updated to record the restarting reason of the server, so that a user can find the restarting reason of the server in the log to accurately judge the running condition of the server.
