Abstract
Techniques for address mirroring of a file system journal are presented. A transactional file system update can correspond to a write operation to be performed at a first participant node of a data storage system. A journal transfer component can transfer the transactional file system update from an initiator node of the data storage system to a first journal associated with the first participant node and recovery information relating to the update to a second journal associated with a second participant node of the data storage system. The recovery information can be determined based on the update. To facilitate the update, a journal descriptor block can be generated and sent to the second participant node, such block comprising the recovery information, which can include transaction state, block addresses involved in the transaction, error correction-related information, or a mirror block address set for the block addresses where desired.
