Abstract:
The storage of data sets in a storage set (e.g., data sets written to hard disk drives comprising a RAID array) may diminish the performance of the storage set through non-sequential writes, particularly if the storage devices promptly write data sets that are followed by sequentially following data sets. Additionally, storage sets may exhibit inconsistencies due to non-atomic writes of data sets and verifiers (e.g., checksums) and an intervening failure, such as an occurrence of the RAID write hole. Instead, data sets and verifiers may first be written to a stored on the nonvolatile media of a storage device before being committed to the storage set. Such writes may be sequentially written to the journal, irrespective of the locations of the data sets in the storage set; and recovery of a failure may simply involve re-committing the consistent records in the journal to correct incomplete writes to the storage set.
