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.
