Abstract
A method and apparatus for delaying the process of freeing data blocks during the processing of a non-volatile transactions log are disclosed. Accordingly, after a system failure, when a storage system is replaying transactions in a non-volatile transactions log, the storage system flushes the data generated from the transactions to disk storage without freeing and data blocks which, as a result of processing the transactions log, are no longer storing data that is part of the active file system. Consequently, the replay of the transactions log takes less time, and the storage system is brought online more quickly.
