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 the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a method, a device and a medium for determining a reason of disc loss.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
In order to provide a supplement for the problem of the reason that the disk loss cannot be located through the running log under the condition that the disk loss of the solid state disk occurs, and enable a technician to distinguish whether the disk loss is caused by a software problem or a hardware problem, the embodiment of the application provides a method for determining the reason of the disk loss. Fig. 1 is a flowchart of a method for determining a reason for lost disk according to an embodiment of the present application. As shown in fig. 1, the method comprises:
s10: when the solid state disk is electrified again after being powered off abnormally, if the solid state disk is determined to be in a lost disk state, whether the reason of the lost disk can be determined according to the running log of the solid state disk is judged. If not, the process proceeds to step S11.
It can be understood that, when the solid state disk is powered on again after being powered off abnormally, the power-on state of the solid state disk at this time needs to be determined first. The power-on state includes a normal state and a lost disk state. If the power-on state of the solid state disk is a normal state, the solid state disk can be directly used; if the power-on state of the solid state disk is a lost disk state, the reason for the lost disk needs to be determined so as to repair the solid state disk.
The operation log of the solid state disk records various information in the working process of the solid state disk, and is generally stored in a NAND FLASH (a nonvolatile FLASH memory medium which can be rewritten and is easy to lose data for a long time) of the solid state disk. When the solid state disk is in a disk losing state, if the information recorded by the derived running log is comprehensive, the reason of disk losing can be analyzed through the running log; and when the derived running log does not record relevant information of power-on and power-off, the situation that the disk is lost due to a log module or other reasons is indicated, and the reason for the disk loss cannot be determined through the running log.
S11: and acquiring the flag bit information stored by the NOR FLASH when the solid state disk is abnormally powered off.
The flag bit information includes flag information of each core in the solid state disk controller when the core is powered off abnormally and capacitance working time information of the capacitor.
S12: and determining the reason of the lost disc according to the zone bit information.
Therefore, when the reason for the lost disk of the solid state disk cannot be determined according to the operation log, the reason for the lost disk needs to be determined in other ways. Specifically, the flag bit information stored by the NOR FLASH when the solid state disk is abnormally powered off is obtained, and the reason for losing the disk is determined according to the flag bit information.
NOR FLASH is a non-volatile FLASH medium that cannot be rewritten, must be erased before writing, and is very stable. In this embodiment, the flag bit information stored by the NOR FLASH when the solid state disk is abnormally powered off includes flag information of each core in the solid state disk controller when the solid state disk controller is abnormally powered off and capacitance operating time information of the capacitor. Because the solid state hard disk controller is multi-core, different software modules can be operated on different cores, the problem of whether the solid state hard disk controller or the software module is available can be checked according to the flag information of each core when the cores are powered off abnormally; meanwhile, the capacitor in the solid state disk is used for supporting the solid state disk to complete the whole abnormal power-off process after the solid state disk is interrupted due to abnormal power-off, so that whether the problem of the capacitor and a hardware circuit exists can be checked according to the capacitor working time information of the capacitor.
It should be noted that, in this embodiment, there is no limitation on the specific way of storing the flag bit information in the NOR FLASH, and there is no limitation on the specific process of determining the reason for the lost disk according to the flag bit, which is determined according to the specific implementation situation.
In the embodiment, when the solid state disk is powered on again after being powered off abnormally, if the solid state disk is determined to be in a lost disk state, whether the reason for the lost disk can be determined according to the running log of the solid state disk is judged; if not, acquiring the flag bit information stored by the NOR FLASH when the solid state disk is abnormally powered off; the flag bit information comprises flag information of each core in the solid state hard disk controller during abnormal power-off and capacitance working time information of a capacitor; and determining the reason of the lost disc according to the zone bit information. Therefore, in the scheme, under the condition that the SSD loses the disk, the reason for the disk loss is determined through the flag bit information stored when the NOR FLASH is powered off abnormally, and the defect that the reason for the disk loss cannot be located through running the log is overcome; the method can enable technicians to distinguish whether the lost disk is caused by software problems or hardware problems, and achieves accurate positioning of the reason for the lost disk when the SSD is powered off abnormally. On the basis, the specific problem is positioned by technical personnel, the hardware problem is avoided, software personnel are positioned, the software problem is unfavorable for positioning the hardware personnel, and the product research and development efficiency is improved.
In order to realize the storage of the flag bit information by the NOR FLASH, as a preferred embodiment, before the solid state disk is abnormally powered down, the method further includes:
setting a preset space in the NOR FLASH and setting abnormal power-off cut-off time;
respectively allocating storage spaces to cores of the solid state hard disk controller in a preset space, wherein the storage spaces are used for storing the mark information when abnormal power-off interruption occurs and the mark information when abnormal power-off is cut off in the corresponding storage spaces of the cores;
and setting a capacitor working time storage space in the preset space to store capacitor working time information of the capacitor when the solid state disk is powered off abnormally in the capacitor working time storage space.
Specifically, a preset space is set in the NOR FLASH of the solid state disk, and the preset space is used for storing the flag information of each core when the solid state disk is abnormally powered off and the capacitance working time information of the capacitor when the solid state disk is abnormally powered off. The size of the preset space is not limited in this embodiment, and is determined according to specific implementation situations. Preferably, the preset space may be set to 4K.
Meanwhile, abnormal power-off cut-off time needs to be set. It can be understood that, when the solid state disk is powered off abnormally, an interrupt pin of the solid state disk controller is triggered, at this time, a power supply of the solid state disk is switched from a high-speed serial computer expansion bus (PCIE) interface (host power supply) to a capacitor inside the solid state disk, the capacitor can support 40-80ms generally, a lower current path of the solid state disk must be completed in this period of time, otherwise, the solid state disk may hang on the disk. The abnormal power-off cutoff time in this embodiment is the last time of the power-off process, that is, the abnormal power-off of the solid state disk must be completed within the abnormal power-off cutoff time, otherwise, the power-off is considered to be failed. In this embodiment, the cut-off time of the abnormal power interruption is not limited, and is determined according to specific implementation conditions. Preferably, the abnormal power-off time may be set to 40ms.
Further, memory spaces are respectively allocated to the cores of the solid state hard disk controller in the preset space, so that the cores store the flag information when the power supply is abnormally interrupted and the flag information when the power supply is abnormally cut off in the corresponding memory spaces. It can be understood that, for each core of the solid state hard disk controller, the storage spaces allocated respectively are used for storing the flag information when the abnormal power down is interrupted and the flag information when the abnormal power down is turned off, and the two kinds of flag information respectively represent the beginning and the end of the abnormal power down. In addition, a capacitor working time storage space is arranged in the preset space and used for storing capacitor working time information of the capacitor when the solid state disk is abnormally powered off.
It should be noted that, in this embodiment, there is no limitation on the specific forms of the flag information and the capacitor operating time information, and there is no limitation on the specific allocation condition of the preset space, which is determined according to the specific implementation condition.
In this embodiment, the storage of the flag bit information is realized by setting a preset space in the NOR FLASH.
In the foregoing embodiment, a specific manner of storing the flag bit information by the NOR FLASH is not limited, and as a preferred embodiment, in this embodiment, the storage space includes a first storage space and a second storage space, and when the solid state disk is powered off abnormally, the storing the flag bit information by the NOR FLASH includes:
respectively storing the mark information during abnormal power-off interruption through the first storage space corresponding to each core;
based on the abnormal power-off cut-off time, storing the mark information when the abnormal power-off cut-off is carried out through the second storage space corresponding to each core;
and storing capacitance operating time information of the capacitor in the capacitance operating time storage space.
It can be understood that, since the storage space is respectively allocated to each core of the solid state hard disk controller in the preset space of the NOR FLASH for each core to store the flag information when the abnormal power-down interruption occurs and the flag information when the abnormal power-down is turned off in the corresponding storage space, two sub-storage spaces may be specifically allocated to each core: the first storage space and the second storage space are used for respectively storing the mark information when the abnormal power-off is interrupted and the mark information when the abnormal power-off is cut off. Therefore, the storage of the flag bit information by the NOR FLASH may specifically be to store the flag information during abnormal power-off interruption through the first storage spaces corresponding to the cores, respectively; based on the abnormal power-off cut-off time, storing the mark information when the abnormal power-off cut-off is carried out through the second storage space corresponding to each core; and storing capacitance operating time information of the capacitor in the capacitance operating time storage space.
In this embodiment, a solid state disk controller is taken as 4 cores for example, which are respectively a core0, a core1, a core2, and a core3, and respectively correspond to four software modules: a Control Module (CM), a management module (AM), a Data Module (DM) and a write-in module (WM); assuming that the preset space of the NOR FLASH is 4K, in a specific implementation, 0-3byte of the 4K space can be used as a first storage space of core0, for storing flag information of the core0 when the power is interrupted due to abnormal power down; 4-7 bytes are used as a second storage space of the core0 and used for storing the mark information when the core0 is cut off under abnormal power-off; preferably, the two kinds of flag information may be embodied as flag numbers 0xa and 0xa, respectively.
Further taking 8-11 bytes as a first storage space of the core1, and storing mark information when the core1 is in power failure under abnormal conditions; 12-15 bytes are used as a second storage space of the core1 and used for storing the mark information when the core1 is cut off under abnormal power-off; preferably, the two kinds of flag information may be embodied as flag numbers 0xb and 0xbb, respectively.
Taking 16-19 bytes as a first storage space of the core2, and storing mark information of the core2 when the power is interrupted due to abnormal power supply; 20-23 bytes are used as a second storage space of the core2 and used for storing mark information when the core2 is cut off under abnormal power-off; preferably, the two kinds of flag information may be embodied as flag numbers 0xc and 0xcc, respectively.
Taking 24-27 bytes as a first storage space of the core3, and storing mark information when the core3 is interrupted in abnormal power-off; 28-31 bytes are used as a second storage space of the core3 and used for storing the mark information when the core3 is cut off under abnormal power-off; preferably, the two kinds of flag information may be embodied as flag numbers 0xd and 0xdd, respectively.
Finally, after 32 bytes, every 4 bytes is a time scale supported by the capacitance electric quantity to serve as a capacitance working time storage space for storing capacitance working time information of the capacitor.
It should be noted that, in the present embodiment, there is no limitation on the specific process of storing flag bit information in the NOR FLASH, which depends on the specific implementation.
In the embodiment, the flag information during abnormal power-off interruption is stored through the first storage space corresponding to each core; based on the abnormal power-off cut-off time, storing the mark information when the abnormal power-off cut-off is carried out through the second storage space corresponding to each core; and the capacitor working time information of the capacitor is stored in the capacitor working time storage space, so that the storage of the zone bit information is realized, and the subsequent reason for losing the disk is convenient to determine.
In order to realize specific storage of flag bit information in NOR FLASH, as a preferred embodiment based on the above embodiments, the storing of flag information during abnormal power-down interruption in the first storage spaces corresponding to the cores respectively includes:
respectively starting a timer corresponding to each core, and respectively applying for the lock by each core; wherein the lock characterizes that only one core can operate NOR FLASH at the same time;
respectively judging whether each core applies for the lock;
if so, writing the mark information during abnormal power-off interruption into a first storage space corresponding to the core, and releasing the lock;
if not, adding the cores to the waiting queue, and returning to the step of respectively applying for the lock by each core.
Specifically, when the solid state disk is abnormally powered off, each core of the solid state disk controller detects abnormal power-off interruption, respectively starts a corresponding timer, and respectively applies for a lock. Note that the lock functions to ensure that only one core is operating NOR FLASH at a time.
Therefore, it is necessary to further determine whether each core applies for a lock. For the core applying for the lock, writing the corresponding mark information during abnormal power-off interruption into the corresponding first storage space, and releasing the lock after the completion; and for cores which do not apply for the lock, adding the cores to a waiting queue (pending list), continuing applying for the lock after the lock is released until all cores write the corresponding flag information in the abnormal power-off interruption into the corresponding first storage space.
Similarly, in the process of storing the flag information at the time of abnormal power-off in the second storage space corresponding to each core, each core also applies for a lock:
when the abnormal power-off cut-off time is determined to be reached according to the corresponding timers, the application of each core to the lock is carried out respectively;
respectively judging whether each core applies for the lock;
if so, writing the mark information when the abnormal power-off is cut off into a second storage space corresponding to the core, and releasing the lock;
if not, adding the cores to the waiting queue, and returning to the step of respectively applying for the lock by each core.
In specific implementation, after all cores write the corresponding flag information during abnormal power-off interruption into the corresponding first storage space, the flag information is incremented along with time, and when the time reaches the abnormal power-off cutoff time determined by the corresponding timer, each core applies for the lock. For the core applying for the lock, writing the mark information when the abnormal power-off is cut off into a second storage space corresponding to the core, and releasing the lock; and for cores which do not apply for the lock, adding the cores to a waiting queue, continuing applying for the lock after the lock is released until all the cores write the mark information when the abnormal power-off is cut off in the corresponding second storage space.
It is understood that the storage of the capacitor operating time information also starts when the solid state disk is abnormally powered down. Accordingly, the storing of the capacitance operating time information of the capacitance in the capacitance operating time storage space includes:
selecting a preset core from each core of the solid state hard disk controller;
starting a capacitor electric quantity timer with a preset core;
and writing the capacitor working time information into the capacitor working time storage space in a preset period through the capacitor electric quantity timer.
Specifically, a predetermined core is selected in the solid state disk controller. For example, core0, i.e. the core of the operation control module CM, is selected; and recording the electric quantity of the capacitor after abnormal power-off through the core. When the solid state disk is abnormally powered off, the core0 detects that the abnormal power-off interruption occurs, then a capacitor electric quantity timer is started, and the timer is used for writing capacitor working time information into a capacitor working time storage space of the NOR FLASH in a preset period.
Assuming that the abnormal power-off time is 40ms, the capacitor should theoretically supply power for at least 40ms after the abnormal power-off occurs. Taking the preset period as 5ms and the capacitor working time information as time count as an example, after abnormal power-off, the capacitor electric quantity timer writes a number into the capacitor working time storage space of the NOR FLASH every 5ms, for example, 5ms writes 1, 10ms writes 2, \ 8230;, 40ms writes 8. Therefore, the actual working time of the capacitor can be confirmed only by counting the time in the working time storage space of the capacitor subsequently.
In this embodiment, flag bit information is stored in the NOR FLASH, so that the reason for the subsequent lost disk can be determined.
In order to realize the final determination of the reason for missing the disc, on the basis of the above embodiment, as a preferred embodiment, the determining the reason for missing the disc according to the flag bit information includes:
judging whether each core triggers abnormal power-off interruption or not according to the mark information in each first storage space during the abnormal power-off interruption;
if the core is determined to have not triggered abnormal power-off interruption, determining that the reason for losing the disk is the fault of the solid state hard disk controller;
if the fact that each core triggers abnormal power-off interruption is determined, whether each core writes mark information when abnormal power-off is cut off in the corresponding second storage space or not is judged;
if at least one core writes the flag information when the power failure is abnormal in the corresponding second storage space, determining that the reason of the lost disk is the software fault in the core;
if the flag information of abnormal power-off cut-off is not written in the corresponding second storage space by each core, acquiring the capacitance working time information stored in the capacitance working time storage space;
and if the working time information of the capacitor does not meet the abnormal power-off cut-off time, determining that the reason for losing the disk is the capacitor and hardware faults.
In specific implementation, after flag bit information stored in the NOR FLASH is obtained, whether each core of the solid state hard disk controller receives abnormal power-off interruption is observed firstly; specifically, whether each core triggers abnormal power-off interruption or not is judged according to the flag information when the abnormal power-off interruption occurs in each first storage space. If the core does not trigger abnormal power-off interruption, determining that the reason for losing the solid state hard disk controller is fault and needing specific inspection; and if the cores are determined to trigger the abnormal power-off interruption, respectively judging whether the cores write the flag information when the abnormal power-off is cut off into the corresponding second storage space. If at least one core writes the flag information of the abnormal power-off cut-off in the corresponding second storage space, determining that the reason for the lost disk is software failure in the core; and if the flag information of abnormal power-off cut-off is not written in the corresponding second storage space by each core, acquiring the capacitance working time information stored in the capacitance working time storage space to judge whether the hardware problems such as capacitance and the like exist. If the capacitor working time information does not correspond to the abnormal power-off cut-off time, for example, the time count is used for calculating that the capacitor is triggered from the abnormal power-off interruption to the power exhaustion, and the duration is not enough to the abnormal power-off cut-off time, the reason that the lost disk is the capacitor and hardware faults is determined.
In the embodiment, the reason for losing the disk is confirmed through the zone bit information, and a supplement is provided for the problem that the reason for losing the disk cannot be positioned through the log; the technical personnel can be made to distinguish whether the problem is caused by a software problem or a hardware problem, and the maintenance of the technical personnel is convenient.
In addition, in the specific implementation, to ensure that the process of determining the reason for the lost disk is performed normally, when the solid state disk is powered on again after being powered off abnormally, if it is determined that the power-on state of the solid state disk is a normal state, the method further includes:
and erasing the flag bit information stored in the NOR FLASH.
It can be understood that, when the solid state disk is powered on again after being powered off abnormally, if the solid state disk is in a normal state at the time, the reason for the disk loss does not need to be determined. However, the flag bit information stored in the previous abnormal power-off state is still retained in the solid state disk. Therefore, in order to ensure that the flag bit information is successfully written in the solid state disk when the solid state disk is powered off next time in an abnormal mode, the flag bit information stored in the NOR FLASH is erased at the moment, and therefore the normal operation of determining the reason for losing the disk when the solid state disk is powered off next time in an abnormal mode is ensured.
