I've got remote console access, but the system has the root disk on the same zfs pool, so I can't simply export and reimport the pool from single user mode. :/ Any ideas on how to achieve this then?

I've sussed it:
# zpool online -e void gpt/disk0
# zpool list
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
void 226G 112G 114G 49% 1.00x ONLINE -
So, is it a bug that autoexpand doesn't work on zpools?
Glad to have got it working, I was down to my last 10G! :)
