Abstract:
A request identifier is employed with various systems and methods in order to enable an application to pause execution during a failure and subsequently resume execution and communication with a storage system once the failure is resolved. An application residing on a node may attempt to access target data on a storage system. The application sends a request to access the target data. The request may be associated with a request identifier that identifies the application. When the storage system experiences a failure, the application receives a failure notification. The application pauses execution as a result of the notification. When the node reestablishes a connection to the storage system, the application resumes execution using the same request identifier. If the resume request is granted, the application is guaranteed that the target data was not modified during the failure.
