Abstract:
A file-mapped volume is a logical volume in which the data storage of the logical volume is the data storage of a regular file associated with the logical volume. The regular file can be a file of a first file system, and a second file system can be built upon the file-mapped volume. These two file systems can have distinct inode address spaces, yet files of the first file system are easily moved to the second file system by changing pointers to inodes of these files. The second file system can be easily copied, attached, or transported by copying, attaching, or transporting the regular file containing the second file system, yet files in the second file system can be accessed in real time via file access routines of the operating system.
