Abstract
Example distributed storage systems, file system interfaces, and methods provide cache coherence management. A system receives a file data request including a file data reference and identifies a data cache location with a coherence value for the file data reference. The system queries a reference data store for a coherence reference corresponding to the file data reference and compares the coherence value to the coherence reference. In response to the coherence value matching the coherence reference, the system executes the file data request using the data cache location.
