ZFS and Btrfs can guarantee 100% data integrity when writes are atomic (drives honor sync commands) and ECC RAM is in use and sufficient redundant data is available for reconstruction when errors are detected. I leave it to the reader to read the ZFS and Btrfs whitepapers that explain precisely why they can make these guarantees. -- Rich P. _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
