Abstract
Systems and methods for reducing locks on a storage layout of a distributed file system by detecting and notifying clients of stale storage layouts. An example method may comprise: receiving a request to modify a file system object associated with a storage layout, the request comprising an index range and the storage layout comprising an index range; determining whether the request is associated with a stale storage layout in view of a comparison of the index range of the request and the one or more index ranges of the storage layout; receiving a lock request to prevent changes to the storage layout; and transmitting at least a portion of the storage layout to update the stale storage layout.
