--- Comment #1 from Christopher Forgeron <chris@acsi.ca> ---
Continuing to dig on this, I see that ctl is intentionally reporting
volblocksize as the physical sector size. The 'blocksize' in ctl.conf is the
logical sector size. 

I'm not sure I agree with this setup - However, perhaps I misunderstand
volblocksize.

With recordsize, the size of the write to disk will be a multiple of ashift, up
to a max of recordsize.

With volblocksize, is the write _always_ volblocksize in size? ie it really is
acting like a sector size?

If so, this behaviour may be correct - If not, then ctl should be advertising
the translated ashift value.
