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.
