Abstract: A method, non-transitory computer readable medium, and computing device that determines when a software failure associated with a virtual storage controller has occurred. At least a portion of a transaction log corresponding to the virtual storage controller is stored in a stable storage device, when the determining indicates that the software failure associated with the virtual storage controller has occurred. A determination is made when the virtual storage controller has rebooted. The at least a portion of the transaction log is retrieved from the stable storage device, when the determining indicates that the virtual storage controller has rebooted. Thereby, state can be preserved and transactions pending, but not yet committed to storage server devices, can be replayed and proceed with minimal or no impact on the client devices originating the transactions.

Abstract: A method, non-transitory computer readable medium, and host device that receives one or more transactions. A state is stored in a transaction log in a volatile memory wherein the state includes information associated with the one or more transactions. The transaction log is stored in a stable storage device when a failure is determined to a have occurred. The transaction log can then be retrieved and replayed subsequent to a reboot. Thereby, state can be preserved and transactions pending, but not yet committed to storage server devices, can be replayed and proceed with minimal or no impact on the client devices originating the write transactions.
