LEVERAGING DISTRIBUTED METADATA TO ACHIEVE FILE SPECIFIC DATA SCRUBBING

摘要

A computer-implemented method, according to one embodiment, includes: determining whether an error has occurred for each block of storage space in memory by sequentially evaluating each of the blocks of storage space. In response to determining that an error has occurred for a given block, the given block is scanned for an identifier at an end of data stored in the given block, and a trailer appended to the identifier is located. Metadata included in the trailer is further used to identify each additional block which corresponds to a same file as the given block, and a data scrubbing procedure is performed on the given block and each of the additional identified blocks. A result of the scrubbing procedure is also output in response to detecting an error in the given block and/or the additional identified blocks.
