Abstract
Apparatus and methods are provided herein for path lookup in a hierarchical file system. An inode associated with a requested object is identified. The inode may be organized in an inode table and identified in the table using an inode number. Ancestry information and size constraint information may also be available for the inode. An inode chain associated with the pathway is identified based, at least in part, on ancestry information associated with the inode for the requested object. A size constraint analysis is performed for the requested object. The size altering operation is selectively performed based on the size constraint analysis.
