tl;dr
(but please read, I suspect this is a ZFS bug that FreeNAS 9.2.1 is working around.)

Unpredictably high zvol used (ZFS bug?) Would file-based iSCSI extents have predictable total usage?

- Will file-based iSCSI extents have unpredictable disk usage? Will any more diskspace be used other than the size of the extent?
- Why does a zvol report "usedbydataset" at all? That's not only for datasets?
- Is this a ZFS bug in the vzol code, or is this blocksize-dependent usage-creep behavior intended by the ZFS designers?
