Abstract:
A method is used in recovering file system blocks of file systems. A first read error is encountered upon reading a file system block of a file system. The file system block includes a first set of chunks. A second read error is encountered upon reading a duplicate copy of the file system block. The duplicate copy of the file system block includes a second set of chunks. Each chunk of the first and second sets of chunks is evaluated. Based on the evaluation, the file system block is recovered.
