ABSTRACT:
A file system migrates a traditional volume to a virtual volume without data copying. In an embodiment, a traditional volume index node is selected for migration. The traditional volume index node is converted to a virtual volume index node. In one embodiment, the virtual volume index node provides both physical address information and virtual address information.
