Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of an operation state monitoring method of an NVMe hard disk according to an embodiment of the present invention. The method may include:
step 101: acquiring operation information of an NVMe hard disk; wherein the operation information includes at least one of temperature information, read-write speed information, write status information, and bad block number information.
It can be understood that the processor of the operation state monitoring device (such as a server) of the NVMe hard disk in this step can obtain the operation information of the connected NVMe hard disk, that is, the information to be monitored in the operation and use process of the NVMe hard disk; as shown in fig. 2, a processor running a control system in a server may obtain respective running information of each NVMe hard disk connected through an NVMe backplane.
Specifically, for the specific content of the operation information of the NVMe hard disk obtained by the processor in the step, the operation information can be set by a designer according to a practical scene and user requirements, for example, the operation information can include the temperature (i.e., temperature information) of the NVMe hard disk when in operation and use; the operation information can also comprise the data read-write speed (namely read-write speed information) of the NVMe hard disk when in operation and use, such as the data read speed and the data write speed; the running information may also include a writing state (i.e., writing state information) when the NVMe hard disk is running and in use, such as a writable state when the NVMe hard disk is capable of writing data or an unwritable state when the NVMe hard disk is incapable of writing data; the operation information may further include the number of bad blocks (i.e., bad block number information) when the NVMe hard disk is in operation.
Step 102: determining the running state of the NVMe hard disk according to the running information; the operation states comprise a normal operation state and an abnormal early warning state.
It can be understood that the abnormal early warning state in this step may be an operation state when the NVMe hard disk has a problem (i.e. a fault), that is, when the operation state of the NVMe hard disk is in the abnormal early warning state, the processor may determine that the NVMe hard disk has a problem, and early warning needs to be performed.
Specifically, for the specific number and types of the abnormal early-warning states in the step, the designer can set the abnormal early-warning states by himself according to the practical scene and the user requirement, for example, the abnormal early-warning states can include any one or more of a writing abnormal state corresponding to the writing state abnormality of the NVMe hard disk, a reading and writing speed abnormal state corresponding to the reading and writing speed abnormality of the NVMe hard disk, a temperature abnormal state corresponding to the temperature abnormality of the NVMe hard disk and a bad block abnormal state corresponding to the bad block number abnormality of the NVMe hard disk; accordingly, the temperature anomaly state may include a mild temperature anomaly state and a severe temperature anomaly state, and the bad block anomaly state may include a mild bad block anomaly state and a severe bad block anomaly state.
Correspondingly, for the specific mode of determining the operation state of the NVMe hard disk by the processor according to the operation information in the step, if the abnormal early warning state includes six abnormal states including a write-in abnormal state, a read-write speed abnormal state, a light temperature abnormal state, a serious temperature abnormal state, a light bad block abnormal state and a serious bad block abnormal state, the processor can sequentially or respectively utilize corresponding contents in the operation information to detect whether the operation state of the NVMe hard disk is in the six abnormal states; if the operation state is not in the six abnormal states, determining that the operation state of the NVMe hard disk is in a normal operation state. For example, the processor may determine whether the written state information in the running information is a writable state; if the state is not writable, namely the NVMe hard disk cannot write data, determining that the running state of the NVMe hard disk is in a writing abnormal state. The processor can judge whether the read-write speed information in the running information is greater than a preset read-write speed, namely, whether the read speed and the write speed in the read-write speed information are both greater than respective corresponding thresholds (namely, the preset read-write speed); and if the running state of the NVMe hard disk is not greater than the preset read-write speed, determining that the running state of the NVMe hard disk is in the abnormal read-write speed state. The processor may determine whether the temperature information in the operating information is greater than a first temperature threshold (e.g., threshold 1 in fig. 3); if yes, judging whether the temperature information is greater than a second temperature threshold (such as threshold 2 in fig. 3); wherein the second temperature threshold is greater than the first temperature threshold; if the temperature is not greater than the second temperature threshold, determining that the running state of the NVMe hard disk is a slight temperature abnormal state; and if the temperature of the NVMe hard disk is greater than the second temperature threshold, determining that the running state of the NVMe hard disk is a serious temperature abnormal state. The processor can judge whether the number of bad blocks in the operation information is larger than the number of early warning bad blocks; if yes, judging whether the bad block number information is larger than the dangerous bad block number (such as a threshold value corresponding to the bad block number in fig. 3); the number of dangerous bad blocks is larger than that of early warning bad blocks; if the number of the dangerous bad blocks is not greater than the number of the dangerous bad blocks, determining that the running state is a slight bad block abnormal state; if the number of the dangerous bad blocks is larger than the number of the dangerous bad blocks, determining that the running state is a serious bad block abnormal state.
Correspondingly, the running state of the NVMe hard disk in this embodiment may be in one or more abnormal early warning states or normal running states.
Step 103: and when the running state is an abnormal early warning state, generating and outputting early warning information corresponding to the running state.
It can be understood that the purpose of this step can be that when the processor determines that the running state of the NVMe hard disk is an abnormal early warning state, the processor reminds the user that the abnormal problem exists in the NVMe hard disk by generating and outputting early warning information corresponding to the abnormal early warning state where the running state is located, so that the user can repair the abnormal problem in the NVMe hard disk in time.
Specifically, when the abnormal early warning state includes six abnormal states including a writing abnormal state, a reading and writing speed abnormal state, a light temperature abnormal state, a serious temperature abnormal state, a light bad block abnormal state and a serious bad block abnormal state, if the running state is in the writing abnormal state, the early warning information generated and output in the step may include writing abnormal information; if the running state is in the abnormal reading and writing speed state, the early warning information generated and output in the step can comprise abnormal reading and writing speed information; if the running state is in a mild temperature abnormal state, the early warning information generated and output in the step can comprise mild temperature abnormal information; if the operation state is in a serious temperature abnormality state, the early warning information generated and output in the step can comprise the serious temperature abnormality information; if the running state is in a slight bad block abnormal state, the early warning information generated and output in the step can comprise the slight bad block abnormal information; if the running state is in a serious bad block abnormal state, the early warning information generated and output in the step can comprise the serious bad block abnormal information.
Correspondingly, for the specific mode of outputting the early warning information corresponding to the operation state by the processor in the step, the method can be set by a designer, as shown in fig. 2, the processor running with the control system in the server can output the early warning information to the management center, so that a user can check the early warning information in the management center; the processor can also output the early warning information to a display for display.
Further, the method provided by the embodiment may further include executing, by the processor, a processing operation corresponding to the running state when the running state of the NVMe hard disk is the target abnormal early warning state; the abnormal target early warning state may be a part or all of abnormal early warning states. If the abnormal early warning state comprises six abnormal states including a writing abnormal state, a reading and writing speed abnormal state, a slight temperature abnormal state, a serious temperature abnormal state, a slight bad block abnormal state and a serious bad block abnormal state, the target abnormal early warning state can comprise four fault conditions which are not serious, namely the writing abnormal state, the reading and writing speed abnormal state, the slight temperature abnormal state and the slight bad block abnormal state, so that the four repairable faults of the NVMe hard disk are automatically removed on line by executing processing operations corresponding to the running states; for example, when the running state is the abnormal writing state, the processor can update and repair the firmware of the NVMe hard disk on line; when the running state is the abnormal reading and writing speed state, the processor can carry out garbage cleaning operation on the NVMe hard disk; when the running state is a slight temperature abnormal state, the processor can adjust the I/O speed of the NVMe hard disk to a preset low-speed value; the preset low-speed value is smaller than a preset normal value corresponding to the normal running state; when the running state is a slight bad block abnormal state, the processor repairs bad blocks in the NVMe hard disk; correspondingly, as shown in fig. 3, when the running state is a serious temperature abnormal state, that is, the temperature information is greater than the second temperature threshold (such as threshold 2 in fig. 3), the processor may generate and output serious temperature abnormal information to remind the user to detect the heat dissipation system or the environmental problem of the NVMe hard disk; when the running state is a serious bad block abnormal state, that is, the number of bad blocks is greater than the number of dangerous bad blocks (such as the threshold corresponding to the number of bad blocks in fig. 3), the processor can generate and output the serious bad block abnormal information so as to remind a user to backup data in advance and replace a hard disk, so that data loss or service interruption is avoided.
Correspondingly, the target abnormal early warning state can be all abnormal early warning states, namely, when the running state of the NVMe hard disk is the abnormal early warning state, the processor executes the processing operation corresponding to the running state. If the running state is a serious temperature abnormal state, the processor can stop the read-write operation of the NVMe hard disk; when the running state is a serious bad block abnormal state, the data in the NVMe hard disk can be backed up to a preset hard disk.
Specifically, when the processor detects that the NVMe hard disk works above the first temperature threshold (for example, 60 degrees), the I/O speed can be reduced, and since the interface of the NVMe is generally 8Gb/s of pcie3.0, the I/O speed of the NVMe hard disk can be adjusted to 5Gb/s of pcie2.0 (for example, a preset low-speed value); after the speed is reduced, the heating value of the chip is reduced, the temperature is reduced to a normal value, and then the I/O speed of PCIE3.0 is recovered; if the temperature of the NVMe hard disk cannot be reduced by adjusting the I/O speed, or the heat dissipation system has a problem, when the temperature exceeds the second temperature threshold (such as 80 ℃) when the NVMe hard disk is detected to work, the read-write operation of the NVMe hard disk can be stopped, and serious temperature abnormality information is output to remind a user of the heat dissipation system or the environmental problem, so that the hardware damage to the NVMe hard disk caused by high temperature is avoided.
The longer the NVMe hard disk is used, the more data is written, and after the whole space is fully written, the old blocks need to be erased first and then written, so that the writing speed is influenced. When the processor detects that the read-write speed information of the NVMe hard disk is not greater than the preset read-write speed, the processor can carry out garbage cleaning operation on the NVMe hard disk; the space which is marked as no data after being used can be erased for one time in advance through garbage cleaning operation, so that data is written in, only the writing operation is needed, and the writing speed is improved.
When the processor detects that the writing state information of the NVMe hard disk is not in a writable state, namely the NVMe hard disk cannot write data, the processor can determine that the firmware of the NVMe hard disk is abnormal, and repair the firmware of the NVMe hard disk by carrying out online upgrade repair on the firmware of the NVMe hard disk; if the processor matches the firmware corresponding to the NVMe hard disk according to the VPD (Vital Product Data, important product data) information of the NVMe hard disk; downloading firmware into an NVMe hard disk and activating the firmware; for example, the processor may execute a Firmware update operation through an open source command line tool nvmecli, download Firmware (FW) into DRAM (dynamic random access memory) of the NVMe disk by using a Download command, and send a Firmware command to activate the Firmware, so as to implement online upgrade repair of the Firmware.
As bad blocks of the NVMe hard disk are gradually increased, the available space of the whole disk is reduced, the frequency of garbage cleaning is increased, and the increase of the bad blocks also has an influence on the stability of the hard disk; therefore, when the processor detects that the running state of the NVMe hard disk is in the slight bad block abnormal state, bad blocks in the NVMe hard disk can be repaired, so that false bad blocks caused by abnormal power failure and other reasons are erased through the bad block repair, and the number of usable blocks is increased. As the number of bad blocks is gradually increased along with use and abrasion, when the processor detects that the running state of the NVMe hard disk is in a serious bad block abnormal state, the processor can output serious bad block abnormal information to remind a user to replace a new disk so as to avoid data loss or service interruption, and the processor can automatically complete the backup of the NVMe hard disk by backing up the data in the NVMe hard disk to a preset hard disk so as to avoid the situation that the user cannot replace the new disk in time.
In the embodiment of the invention, when the running state of the NVMe hard disk is an abnormal early warning state, the early warning information corresponding to the running state is generated and output, so that the monitored abnormal situation can be early warned in time before the NVMe hard disk is completely invalid, potential risks can be timely identified, serious faults such as downtime and data loss are avoided, and accordingly repairable faults of the NVMe hard disk can be timely removed, and the situation that small faults accumulate into unrepairable large faults is avoided.
