摘要:
Methods, systems, and computer program products for performing an input/output (I/O) operation that includes a virtual drain. According to one aspect, the subject matter described herein includes a method for performing an input/output operation that includes a virtual drain. The method includes receiving a request to perform a consistent operation involving a storage entity, and in response to receiving the request: arresting write requests to the storage entity; performing a virtual drain, where performing a virtual drain includes identifying, and indicating as deferred, pending writes to the storage entity; performing the consistent operation; releasing write requests to the storage entity; and processing each deferred write using information that is associated with the write and that describes the context in which the write request was accepted.
