Abstract
A system and method for allowing a distributed, coherent network filesystem to have virtual filesystem instantiations existent on any number of client nodes as well as on the server node that maintains the physical instantiation. On the server node only one image of the filesystem is visible even though two instantiations (physical and virtual) have been realized on that node. The rendering the physical instantation invisible and inaccessible is accomplished by performing a "takeover" of the physical filesystems data structures by the virtual filesystems mounting subroutines.
