A computer-implemented method for host communication in a clustered file system may include 1) identifying a cluster file system site comprising at least one host that performs data operations on a storage unit, 2) identifying a storage management application that manages the storage unit, 3) transmitting, by an initial host, an initial data operation directed to a location of the storage unit, where the data operation comprises a notification signal that commands the notification of the initial host upon a subsequent host attempting to access the location, 4) transmitting, by the subsequent host, a subsequent data operation directed to the location of the storage unit, and 5) notifying the initial host, by the storage management application, that the subsequent host attempted to access the location of the storage unit. Various other methods, systems, and computer-readable media are also disclosed.
