Patent ID: 8914345

Claim:
A computer-implemented method for host communication in a clustered file system, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: identifying a cluster file system site comprising at least one host that performs data operations on a storage unit; identifying a storage management application that manages the storage unit; 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; blocking, by the storage management application, performance of the initial data operation for at least a period of time in response to the notification signal; transmitting, by the subsequent host, a subsequent data operation directed to the location of the storage unit; in response to detecting the subsequent data operation, notifying the initial host, by the storage management application, that the subsequent host attempted to access the location of the storage unit by stopping the blocking of performance of the initial data operation, processing the initial data operation, and reporting successful completion of the initial data operation.
