The mirror vdev will only be as large as the original device, but once the mirror completes resilvering, you can remove the old device and grow the remaining device to full size (it may do that anyway based on the setting of the auto expand property of the zpool. The default under 9.1 is NOT to autoexpand:

Thanks.
I did not realize that there was such an interesting and useful option :)

# zpool get autoexpand tank
NAME  PROPERTY    VALUE   SOURCE
tank  autoexpand  off     default
