Holy what the heck, no it doesn't! One big issue with zfs is that you
CANNOT shrink a pool's size once it's been created, for any reason. You
can't remove vdevs, and any replacement disk must bigger or exactly
equal in size; even a disk with one less sector and you're SOL. This is
my biggest gripe with zfs by far and in fact I just asked freebsd-fs
about this less than a week ago wondering if it had been addressed
finally (it hasn't).
