Abstract
Systems and methods of managing concurrent log writes to a transaction log are provided. A system may include: a transaction log residing on a non-volatile storage medium for logging metadata transactions of a file system; and a plurality of transaction log buffers, associated with the transaction log, residing in volatile memory. A first write operation may be initiated to write first contents of at least a first of the plurality of transaction log buffers to the transaction log. Concurrently to a performance of the first write operation, a second write operation may be initiated to write second contents of at least a second of the plurality of transaction log buffers to the transaction log.
