Abstract
Techniques are provided for asynchronous reservation of storage volumes in a storage system with persistent storage of reservation data. One method comprises obtaining, by a target storage device, a reservation command from a host device that requests to reserve a storage volume of the target storage device; creating a new execution thread to process the reservation command, wherein an execution of the reservation command is asynchronous; storing an intermediate result of the reservation command in a persistent storage, wherein the stored intermediate result allows the execution of the reservation command to restart from an execution point following the storage of the intermediate result; and initiating a notification to the host device of the reservation of the storage volume in response to a completion of the execution of the reservation command. The target storage device may recover from a failure during a processing of the reservation command by loading a stored intermediate result from the persistent storage.
