Detailed Description
At present, the cold data is generally checked periodically on the data of the whole hard disk, and the reliability of the data of the hard disk can be improved to a certain extent by the checking mode. However, this method of all verification is very labor-intensive and costly, which means that the cycle time for verifying data cannot be too short. If the cycle time is too long, although the workload and cost of verification can be reduced to a certain extent, if data in a certain area is in error, the data in the area may be more and more due to long-term non-verification, and as time goes on, all the associated data capable of recovering the data in the area are in error, which finally results in the problem that the data cannot be recovered and is lost permanently. And for each area on the hard disk, no definite time length exists from data error to data complete recovery, namely, a time period is difficult to determine, and the data is verified according to the time period, so that the problem of untimely data verification can be avoided.
The verification method provided by the invention is used for purposefully verifying the high-temperature area in the preset period time with the relative time length shorter than the second preset period time, so that the problem that data is lost or even cannot be recovered due to overhigh temperature is solved. The reliability of the data is improved.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 invention.
Fig. 1 is a flowchart of a hard disk cold data verification method according to an embodiment of the present invention, where the method may specifically include:
step S101: and acquiring the temperature parameters of each area on the hard disk baseplate in real time.
Since temperature is one of the causes of data errors, other parameters are also possible here if they are available.
Step S102: and judging whether the regions with the temperature parameters larger than the preset temperature threshold exist in each region within a first preset time period, if so, entering step S103, and if not, entering step S104.
Specifically, the same preset temperature threshold may be set for each region, but if the suitable preset temperature thresholds for each region are found to be different in the repeated verification process, certain adjustment may also be performed.
In addition, if the areas with the temperature parameters larger than the preset temperature threshold do not exist in each area in a plurality of first preset time periods, the preset temperature threshold of each area is not properly set, and needs to be adjusted.
Step S103: and verifying the data of the area with the temperature parameter larger than the preset temperature threshold value.
Step S104: and verifying the data of each area which is not verified and recovered within a second preset time period.
It should be noted that, in the prior art, when data is verified, it is necessary to verify the data of the entire hard disk, because a specific area where the data is in error cannot be determined, but the present invention considers the reason of causing the data error. At present, the reasons that can be determined to cause the data to have bit attenuation are mainly: complete idle or excessive wear, contamination such as dust, background radiation, and high heat.
The method has the advantages that the method is not good for measuring pollutants such as excessive wear and dust and background radiation, but the temperature can be easily measured, so that the region with the overhigh temperature is purposefully checked, in order to avoid the problem that the whole hard disk is too long in idle time, the hard disk is still checked except for the region with the overhigh temperature, the time period for checking the whole hard disk can be longer than the time period for checking the region with the high temperature, but the checked region can not be checked, and the workload for checking the whole hard disk is reduced on the basis of ensuring the safety and reliability of data.
In addition, if other factors influencing the attenuation of the data bits of the hard disk can be measured, the data of the area with high similar checking temperature can be checked, for example, background radiation is measured, and the data is checked according to the measured result. Other factors can be controlled, such as cleaning each area of the hard disk regularly or installing a dust removal device on the basis of verification. There are other similar schemes, which are not described in detail herein.
Based on the foregoing embodiment, in another specific embodiment provided by the present invention, the data verification process for the area with the temperature greater than the preset temperature threshold may be further defined as:
judging whether the data of the area has error data or not, wherein the area is an area with the temperature larger than a preset temperature threshold;
if so, acquiring data in the same stripe as the error data from the data on the hard disk, and performing data recovery on the error data according to the data in the same stripe as the error data. Data which can be mutually recovered are generally stored on the same striped area;
if not, the area does not need to be subjected to data recovery. If a plurality of areas with the temperature larger than the preset temperature threshold exist, the next area can be verified until all the areas with the temperature larger than the preset temperature threshold are verified.
Based on any of the above embodiments, it is mentioned in the first embodiment that the preset temperature threshold may be adjusted if it is not appropriate. Therefore, in another specific embodiment of the present invention, it can be further modified as follows:
after the data of the regions with the temperature parameters greater than the preset temperature threshold are verified, or after the number of the regions with the temperature parameters greater than the preset temperature threshold are judged to exist in each region, whether the number of the regions with the temperature parameters greater than the preset temperature threshold exceeds the preset number in a first preset time period is judged, and if yes, the duration of the first preset time period is shortened.
It should be noted that, for the adjustment of the preset temperature threshold, one or more of the number of the regions in which the temperature parameter is greater than the preset temperature threshold in the consecutive first preset time periods may be referred to, if the number of the regions in the consecutive first preset time periods is generally greater, it is indicated that the duration of the first preset time period needs to be decreased, otherwise, if the number is generally greater, it is indicated that the duration of the first preset time period needs to be increased, the specific adjustment condition and manner are the same as the reduction of the duration of the first preset time period, and the temperature parameters in the first preset time periods are used as the basis for adjusting the duration of the preset time periods, which is a more preferable embodiment, and it is able to avoid unreasonable adjustment of the duration of the preset time periods due to an unexpected situation.
Based on any of the above embodiments, it is considered that when data is written in a hard disk, data is written into each region one by one in sequence, and if a certain region has completed IO service processing but the region is not completely full of data, data will continue to be written into the region when IO service processing is performed next time, so that if data in the region is faulty, data writing of subsequent IO service will be inevitably affected. Therefore, in another embodiment of the present invention, the following steps can be further modified:
receiving information of IO service processing completion, judging whether data verification is performed on an area where IO service is completed in a third preset time period, and if not, verifying and recovering the data of the area.
It should be noted that the duration of the third preset time period is necessarily less than the duration of the first preset period, but the duration of the third preset time period may be determined as appropriate according to experience of verifying data for a long time, and when the duration is inappropriate, the duration may be adjusted as appropriate. For example, if too few regions need to be verified in a plurality of third preset time periods, it means that the time period is set too large, and if too many regions need to be verified, it means that the time period is set too small.
Based on the above embodiment, for most hard disks, the frequencies and regions where various bit attenuations occur have certain similarities, and if a certain hard disk is checked and debugged for a long time, a suitable parameter can be obtained, so that the reliability of data in the hard disk is greatly increased, and then various parameters of the hard disk also have good reference values for parameters configured by other hard disks. Therefore, in another specific embodiment of the present invention, further improvements can be made, specifically including:
and outputting parameters such as the duration of the first preset time period, the second preset time period and the third preset time period, the preset temperature threshold value, the preset quantity threshold value and the like.
Of course, it is conceivable that since the parameters on the hard disk can be derived as the parameters configured by other hard disks, the hard disk may also use the already configured parameters as various parameters for the hard disk verification, and therefore, the present invention may be further improved as follows:
receiving parameters such as the durations of the first preset time period, the second preset time period and the third preset time period, the preset temperature threshold value and the preset quantity threshold value, and if the parameters are not suitable in the data verification process, adjusting the parameters according to the method in the embodiment.
