For files smaller than the default (128K) or the user-defined value, the recordsize will be the smallest power of two between 512 bytes and the appropriate upper limit. For anything above the value, it's the defined recordsize for every block in the file. Variable recordsize is only for single block files. There's no tail packing using variable recordsize in ZFS (yet?).
