Abstract: Systems and methods for managing file operations over shared content in the presence of two or more heterogeneous file systems. A virtual file system provides data consistency pertaining to asynchronous interactions between the heterogeneous storage systems. Operations of the virtual file system include receiving a file system call from a first storage environment for performing one or more data operations at a second storage environment. After receiving the file system call, the virtual file system issues file system calls to the second storage environment and records a first set of metadata. To determine if and when the one or more data operations at the second storage environment have completed, the virtual file system accesses a second set of metadata from the second storage environment. The two sets of metadata are compared. If there are differences, then the virtual file system performs time delays until the two sets of metadata agree.
