Hi! Till now I thought btrfs does not use journaling at all, but utilize COW approach for operations atomicity. But, when I have seen in "Btrfs Timeline": July 31, 2008: Data=ordered mode support, preventing null bytes in a file after a crash. I have begun to doubt - whether I correctly understand atomicity and transactions concepts of btrfs.
Please, can you clear these doubts? Is btrfs uses any kind of journaling and what for "Data=ordered"? I guess, may be it for metadata-data write order but without journal involving, isn't it? Thanks! _______________________________________________ Btrfs-devel mailing list [email protected] http://oss.oracle.com/mailman/listinfo/btrfs-devel
