This will depend on who you ask. Over the long term, btrfs will support a number of stronger checksums for metadata and data. There are 256 bits reserved in the metadata blocks, and the file data checksums don't require a fixed size, so it will be possible to have different sized checksums on different files. In practice, 32 bit crcs are a good tradeoff between performance and safety. Some people will surely want better, and we'll examine other algorithms as the FS matures. -chris _______________________________________________ Btrfs-devel mailing list [email protected] http://oss.oracle.com/mailman/listinfo/btrfs-devel
