Disclosed are “black-box leases” that protect information consistency and that allow for information sharing in a distributed file system while hiding from a client information about other clients' use of the file system. This information hiding also allows greater concurrency because changes to the file system are permitted as long as they do not affect the leases as observed by the clients. For each data field protected by a black-box lease, a client has a two-value data structure: SelfValue represents the client's intended use of the data field, and OtherValue is an aggregation of the other clients' intended uses of that data field. Knowing only this aggregate OtherValue, but without knowing any specifics of the other clients' usage patterns, the client knows how it may use the data field without adversely affecting the consistency of data in the distributed file system.
