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.

Abstract: A method, non-transitory computer readable medium and storage server computing device that determines when a generated storage operation corresponds with one of a set of predefined storage operations. The storage operation is executed and a result of the execution of the storage operation is withheld from a file system, when the determining indicates that the storage operation corresponds with one of the set of predefined storage operations. A determination is made when a consistency point operation has completed. The result of the execution of the storage operation is presented to the file system, when the determining indicates that a consistency point operation has completed. 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 in a journal following a recovery.
