Abstract

The invention discloses a restoration method, device and apparatus for write-in operation process of storage equipment. The restoration method comprises the steps that in response to an instruction ofwriting data into a plurality of specified target pages, adding counting marks to each target page, writing data into the target pages, and sequentially increasing the numerical values of the counting marks according to the sequence of the written data of the target pages corresponding to the counting marks; in response to a data reading instruction, arranging the target pages corresponding to the counting marks according to an ascending sequence of the counting marks; and sequentially reading the data corresponding to each arranged target page and finding out abnormal data and the position of the abnormal data. According to the invention, the fault analysis difficulty is reduced, and the fault analysis efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of computer storage, in particular to a method, device and device for restoring a writing operation process of a storage device. Background technique [0002] During the use of the storage device, various data are written interleaved. With the continuous writing of data, the storage device needs to write additional mapping table (mapping table), intermediate data of garbage collection, data of garbage collection and physical block status information and other data. [0003] If the data is found to be abnormal when reading the data, it is likely to be the data written a long time ago. The current state information maintained inside the storage device is already the information that is continuously superimposed after the error occurs. The on-site environmental parameters at the time of the error have changed. , it is difficult to obtain the data of the wrong site for analysis. [0004] At present, th...
