Wherein, when the knowledge of bag tail tag comprises test file name, be the title utilizing test file data cell being carried out to consistency desired result, visible, the test file name known as bag tail tag is tested corresponding test file associate with actual, thus can carry out the consistency verification of data of being correlated with.When bag tail tag know comprise equipment Serial Number time, be utilize the sequence number of equipment performing consistency verification of data to verify, thus also can carry out the consistency verification of data of being correlated with.When bag tail tag know comprise test thread number time, be utilize the thread number of thread performing consistency verification of data to verify, thus carry out the verification of being correlated with.
Particularly, in an embodiment of the invention, when described bag tail tag knowledge comprises test file name, utilize the described bag tail tag knowledge of carrying in the first data cell to carry out consistency checking specifically to comprise: judge whether the title of the test file of current execution consistency verification of data mates with the test file name in the first data cell, if, then determine that consistency verification of data is passed through, otherwise, verify unsuccessfully.Based on this, achieve the verification of the test file to current execution consistency verification of data, enriched the content of consistency verification of data, improve the reliability of verification.
In an embodiment of the invention, when described bag tail tag knowledge comprises equipment Serial Number, utilize the described bag tail tag knowledge of carrying in the first data cell to carry out consistency checking specifically can comprise: judge whether the sequence number of the equipment of current execution consistency verification of data mates with the equipment Serial Number in the first data cell, if, then determine that consistency verification of data is passed through, otherwise, verify unsuccessfully.Based on this, achieve the verification of the equipment to current execution consistency verification of data, enriched the content of consistency verification of data, improve the reliability of verification.
In an embodiment of the invention, when described bag tail tag knowledge comprises test thread number, utilize the described bag tail tag knowledge of carrying in the first data cell to carry out consistency checking can comprise: judge whether the thread number of the thread of current execution consistency verification of data mates with the test thread number in the first data cell, if, then determine that consistency verification of data is passed through, otherwise, verify unsuccessfully.Based on this, achieve the verification of the thread to current execution consistency verification of data, enriched the content of consistency verification of data, improve the reliability of verification.
In order to clearly embody in one embodiment of the invention the process realizing consistency verification of data, see Fig. 2, the data cell minimum for each and data block, this checking procedure comprises:
Step 201: pre-set the knowledge of bag tail tag and comprise: test file name, equipment Serial Number and test thread number.
Step 202: when each data block is stored in memory device such as disk by needs, calculate LBA (Logical Block Addressing) corresponding to each data block (LBA).
Step 203: each LBA calculated is carried at respectively in the packet header of corresponding data block.
Step 204: carry the bag tail tag pre-set and know in the bag tail of each data block.
Through the process of above-mentioned steps 203 and step 204, the packet header of each data block and the structure of bag tail can be as shown in table 1 below.
Table 1
Can find out according to table 1, the knowledge of bag tail tag comprises: the test thread number being positioned at last 4 bits, is positioned at the equipment Serial Number of the 5th bit reciprocal to the 12nd bit reciprocal, and is positioned at the test file name of the 13rd bit reciprocal 20th bit extremely reciprocal.
Step 205: each data block after data structure being changed is stored in disk respectively.
Step 206: run corresponding test file by the equipment of current execution consistency verification of data, and the thread calling current execution verification starts to perform consistency verification of data.
Step 207: for the current data block needing verification, be designated as data block 1, obtain the deviation post that this data block 1 is storing in disk.
Step 208: utilize the LBA carried in the packet header of data block 1, whether the memory location (deviation post namely calculated) that verification stores this data block 1 is correct, if correctly, then performs step 209, otherwise, consistency desired result failure.
In this step, the disk calculations of offset formula that the writing position of data block expection is corresponding is as follows: disk offset=LBA × Block_Size, and wherein, offset is disk deviation post, and Block_Size is the size of data block; Utilizing after the LBA in data block 1 calculates expection disk deviation post offset, actual disk deviation post when can store in disk with data block 1 is current contrasts, if different, then represent that data block 1 is not stored in correct position, consistency verification of data failure, if identical, then can continue follow-up data consistency desired result process.
Particularly, see Fig. 3, under normal circumstances, there is corresponding relation in LBA and the offset of data block.Such as content as shown in block correct in figure, namely when the LBA carried in data block is 2, the deviation post that data block is expected in disk is 1024.But erroneous block shows, the LBA being the data block of 1024 positions in disk skew is 100, shows that the LBA of this position is not written to the position of expection write, but has occurred position deviation, write this position by mistake.Thus conveniently can determine that the inconsistent reason of data is that the dislocation of data block causes.
In addition, in this step, in the memory location mistake due to data block 1 after consistency verification of data failure, corresponding storage corrigendum process can be performed, comprise: according to the LBA carried in data block 1, determine the correct memory location of data block 1 in described memory device, data block 1 is stored into correct memory location.
Step 209: in disk, from the packet header of data block 1, searches frame by frame backward, judge before the packet header finding next data cell, whether find the bag tail tag carried in data block 1 and know, if found, then perform step 210, otherwise, determine consistency desired result failure.
If the position storing data block 1 in disk starts the bag tail not finding data block 1, but directly find again the packet header of next data block 2, illustrate, between data block 1 and data block 2, data overlap occurs, then consistency desired result failure.Such as, shown in Figure 4, under normal circumstances, each data block can find corresponding packet header and bag tail.But the situation in the diagram, it is obviously the position that data block B has striden into data block A place, there is the overlap between data block, the bag tail information of natural data block A has also just been override by data block B, by the confirmation of packet header and bag tail, the data inconsistence problems that data block overlap causes just clearly can be seen.
Step 210: judge whether the title of the test file of current execution consistency verification of data mates with the test file name in data block 1, and whether the sequence number of the equipment of current execution consistency verification of data mates with the equipment Serial Number in data block 1, and whether the thread number of the thread of current execution consistency verification of data mates with the test thread number in data block 1, if all mated, then perform step 211, any one does not mate, then consistency desired result failure.
Step 211: consistency verification of data success.
