Sector size of a zvol

[Pete French]

So, I was trying to create a disc witha  sector size of 4096 bytes, and I
assumed that simply creating a zvol with that blocksize would do the trick.
But it appears that whatever the blocksize is on the xvol, diskinfo is
reporting the sector size as 512 bytes.

I this the intended behaviour ? I dont have a Solaris system to hand to
test it on, so I have no ida if this is BSD specific or not.

cheers,
