Instead, when the server is restarted, Mac OS X simply replays recent transactions in the journal, bringing the system up-to-date and resuming operations that were interrupted during the failure. This eliminates the need to perform a consistency check on the entire file system during startup. The operating system can use the journal to return the file system to a known, consistent state after a failure. When journaling is turned on on a storage volume, the server automatically tracks file system operations and maintains a continuous record of these transactions in a separate file, called a journal. Journaling accelerates the recovery time after an unexpected shutdown, significantly improving the availability of server and storage systems. This process can take hours on a multi-terabyte volume, resulting in an unacceptable period of server downtime. Before the server can restart and resume services, it must perform a consistency check that requires going through the entire file system, block by block. In an unjournaled file system, drives are in an unknown state after a failure, meaning that there is no record of their activity just prior to the shutdown.
