Patent 9471595 was granted and assigned to EMC on October, 2016 by the United States Patent and Trademark Office.
A method is used in recovering file mapping information in file systems. Metadata of a file of a file system is evaluated. Mapping information associating the file to a file system hierarchy of the file system is missing a reference to an inode of the file. Based on the evaluation, the mapping information is updated for including the file to the file system hierarchy of the file system.
