Abstract
A method is used in recovering duplicate blocks in file systems. A duplicate file system block is detected in a file system. The duplicate file system block is referred by a first inode associated with a first file of the file system and a second inode associated with a second file of the file system.

Each inode of the set of inodes refer to the duplicate file system block. Based on the determination, the set of inodes is updated.
