Abstract
Methods, non-transitory computer readable media, and computing devices that execute a storage operation, without journaling the storage operation in a log, and withhold from a file system a list of freed inodes including an indication of an inode freed as a result of the execution of the storage operation. A consistency point operation is then initiated that retrieves storage operations logged as journal entries in the log and commits a result of each of the storage operations to data storage devices. A list of available inodes is updated based on the list of freed inodes, when the consistency point operation is determined to be complete. This technology reduces the number of storage operations that are required to be journaled to maintain consistency of a file system, thereby reducing the runtime resources required to facilitate the journaling and replay resource required to replay the storage operations following a recovery.
