Is there some way to determine the size of disks discovered with
`format'
An attempt to create a 2 disk mirror failed with the message that the
disks were different sizes, but I thought they were the same size... I
must have used the wrong identifier for one of the disks... so to find
the matching disk how can I tell what size the discs turned up by
format are?
$ pfexec format

It's mostly the cylinder numbers that you need to watch out for.
If you have devices with the same claimed manufacturer size but
different geometry, I'd create a slice of the maximum size on the
smaller disk, then create a slice with the same number of cylinders
on the larger disk, and then mirror those two slices.
