Systems and methods for host communication in a clustered file system

A system for host communication in a clustered file system, the system comprising:

• an identification module programmed to identify a cluster file system site comprising at least one host that performs data operations on a storage unit, and programmed to identify a storage management application that manages the storage unit;
• a transmission module programmed to:
• transmit, 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;
• transmit, by the subsequent host, a subsequent data operation directed to the location of the storage unit;
• block, by the storage management application, performance of the initial data operation for at least a period of time in response to the notification signal;
• a notification module programmed to, in response to detecting the subsequent data operation, notify 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;
• at least one processor configured to execute the identification module, the transmission module, and the notification module.

A non-transitory computer-readable medium comprising one or more computer-executable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

• identify a cluster file system site comprising at least one host that performs data operations on a storage unit;
• identify a storage management application that manages the storage unit;
• transmit, 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;
• block, by the storage management application, performance of the initial data operation for at least a period of time in response to the notification signal;
• transmit, by the subsequent host, a subsequent data operation directed to the location of the storage unit;
• in response to detecting the subsequent data operation, notify 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.
