Hello all, Our research group at Iowa State University and Western Digital have designed and developed a generic redo log interface for file system checkers (fsck). The source code is available at: https://git.ece.iastate.edu/data-storage-lab/prototypes/rfsck The design of our redo log is based on the undo log feature available in e2fsck and provides a transaction interface. We identified that the existing undo log in e2fsck is not properly implemented and that there are issues concerning synchronizing updates across the undo log file and the device. For further details please refer to our paper: https://www.usenix.org/system/files/conference/fast18/fast18-gatla.pdf I request the community to kindly review our work and provide us some feedback. Regards Om Rameshwar Gatla
