If you enlarge the underlying drive, then you can tell zfs to make use of
the available space
with a command like:

zpool online -e rpool c2t0d0

where you have to give the pool name and the name of the device.

You can only enlarge a pool this way; shrinking a device isn't possible.

And you may need a reboot for the guest to see the changes (eg on AWS,
I have to reboot instances to pick up the size changes of EBS volumes).
