Abstract
A method, system, and apparatus to encapsulate one or more file systems in a union of file systems without modifying or copying information in each file directory entry in each file system are presented. In one embodiment, this is accomplished in part by linking an inode list file from the file system to be encapsulated with an inode list file of the union of file systems, and merging a free extent map of the to-be-encapsulated file system with the free extent map file of the union file system.
