And Serviceability, RAS).
Detailed description of the invention
Fig. 1 shows the schematic flow chart of the application one embodiment method.
Fig. 2 shows the schematic flow charts of the method for another embodiment of the application.
Fig. 3 shows the schematic block diagram of one device of the application.
Specific embodiment
Below in conjunction with attached drawing, the technical solution in the application is described.
As shown in Figure 1, Fig. 1 shows a kind of method for storing log information in isomery mixing memory system, comprising:
Step 110, judge in NVM of the system for storing kernel log with the presence or absence of data；
Step 120, when, there are when data, data present in the NVM being temporarily stored in the system kernel in the NVM
In the caching temporarily distributed；
Step 130, user empties the data stored in the NVM after reading the data in the caching.
Optionally, as the application one embodiment, the method also includes: when described for storing kernel log
When data being not present in NVM, the data filled in caching that the system kernel temporarily distributes are stored into the NVM.
Optionally, as the application one embodiment, the method also includes: when in the NVM there are when data, by institute
It states data present in NVM and resolves to readable form data and be stored in the system log of the system.
In the case where powering off suddenly present invention primarily contemplates server in isomery mixing memory system, it is stored in memory buffer
The kernel log in area is not recorded timely, and the loss of kernel log is caused.Therefore, set forth herein in a kind of mixing of isomery
The fault-tolerant method of kernel log in deposit system carries out fault-tolerant processing mainly for the kernel log in isomery mixing memory system,
It is realized using the non-volatile characteristic of nonvolatile memory nonvolatile memory (non-volatile memory, NVM) to kernel day
Will it is fault-tolerant, by the redirection of kernel log buffer area, provide realtime unification management kernel log fault tolerant mechanism, enhance system
RAS characteristic.The design structure of the fault-tolerant method of kernel log includes: that kernel log is fault-tolerant in a kind of isomery mixing memory system
Module and kernel log storage and processing module.The fault-tolerant method flow diagram of kernel log is such as in a kind of isomery mixing memory system
Shown in attached drawing 2.
The fault-tolerant module of kernel log refers to that kernel thread reads NVM log space and says if NVM log space has data
Bright last time machine is abnormal power-down, and NVM saves the kernel log before last time power-off, and it is empty that kernel thread need to first read NVM log
Between in data keep in the caching buf of kernel temporarily distributed；Then the data on NVM log space are emptied；If NVM
Log space does not have data, the data copy that operating system has been filled in kernel log buf to NVM log space.Kernel log
Buf is redirected to NVM log space.
Kernel log storage and processing module refer to that NVM User space monitoring process reads operating system in kernel log buf
The NVM data that the data copy having been filled with may be kept in into NVM log space is then parsed into readable shape if there is data
Formula is stored under the catalogue of system log.NVM User space log parses process and parses NVM log, and dmesg can also read NVM
Log.
Therefore, the method fault-tolerant set forth herein kernel log in a kind of isomery mixing memory system, it is mixed mainly for isomery
The kernel log closed in memory system carries out fault-tolerant processing, by the redirection of kernel log buffer area, provides unified pipe in real time
Kernel log fault tolerant mechanism is managed, the reliability, availability, scalability (Reliability, Availability of system are enhanced
And Serviceability, RAS).

Determination unit 310 is used to judge in NVM of the system for storing kernel log with the presence or absence of data；Processing unit 320, institute
Processing unit is stated for when, there are when data, data present in the NVM being temporarily stored in the system kernel in the NVM and are faced
When the caching that distributes in；The processing unit is also used in user after reading the data in the caching, empties the NVM
The data of middle storage.
Optionally, as the application one embodiment, the processing unit 320 is also used to when described for storing kernel day
When data being not present in the NVM of will, the data filled in caching that the system kernel temporarily distributes are stored to the NVM
In.
Optionally, as the application one embodiment, the processing unit be also used to when in the NVM there are when data,
Data present in the NVM are resolved to readable form data to be stored in the system log of the system.
