I've read the Illumos link and did not see options for identifying the disk
block size. I also saw that the page did give options for setting the
ashift=12 those options don't apply to SmartOS. In the SmartOS wiki (Hardware
Requirements - SmartOS Documentation - SmartOS Wiki) one of the known issues is
support for 4k disks.
Is there a way to tell what the current volume block size is?
