I guess that'll teach me yet again to ask the right question.

machine has multiple pools (rpool, tank)
pool tank has multiple vdevs all raidz2, the drives in the pool vary from 500G 
to 3T in capacity.
c64t0d0 has failed and no longer responds to I/O, so it can't be queried with 
the fdisk trick above.
I know the failed disk is 1.5T, but before I go buy the replacement, I want to 
know if I can replace it with a 1T, or if it needs to be 2T (since 1.5T was a 
stopgap size instead of a longterm not-too-big-not-too-small size I saw it).
ZFS knows that a device I'm about to stick in is too small, so how do I query 
that information for required minimum size?
