Abstract: Technology is disclosed for improving performance during playback of logged data storage operations. The technology can monitor a log to which data storage operations are written before data is committed to a volume; determine counts of various types of data storage operations; and when the counts exceed a specified threshold, cause the data storage operations to be committed to the volume. Some data storage operations can be coalesced during playback to further improve performance.

Abstract: A method, non-transitory computer readable medium, and source storage server computing device that mirrors dirty data to a destination storage server. The dirty data corresponds to storage operations not yet committed to one or more data storage devices of an aggregate to be transitioned. Ownership of the data storage devices is released. Teardown processing for the aggregate is performed subsequent to releasing ownership of the data storage devices. With this technology, the flushing or committing of dirty data to data storage devices is performed by a destination storage server after a data container is transitioned to the destination storage server. Additionally, non-critical teardown processing is also performed after a data container or aggregate is transitioned to the destination storage server. Accordingly, the duration of planned data container transitions can advantageously be reduced and aggregates can be brought online by a destination storage server for data access by applications more quickly.

Abstract: A method, non-transitory computer readable medium and storage server computing device that allocates monotonically increasing sequence numbers to storage operations based on an order of the storage operations corresponding entries in a log. The storage operations are sequenced including by identifying a subset of the storage operations that are parallelizable. A file system data structure is allocated and populated with data associated with one of the storage operations. A determination is made when a rollback is detected based on whether a replay ledger index field of the file system data structure comprises one of the sequence numbers that is greater than another one of the sequence number corresponding to the one of the storage operations. The another one of the sequence numbers is inserted into the replay ledger index field, when the determining indicates that a rollback is not detected.
