Abstract
Disclosed herein are methods, systems, and processes track access patterns of inodes, and to issue read-ahead instructions to pre-fetch inodes into memory. An inode is accessed and a directory of the inode is determined. Also determined is whether an entry for the directory exists in a global inode list. If the entry exists in the global inode list, whether a file structure of the directory is sequential or non-sequential is determined. If the entry does not exist in the global inode list, a new entry for the directory is added in the global inode list.
