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?

Ah, no, that didn't work. It's still the same size:

	# zpool get all void
	NAME  PROPERTY       VALUE       SOURCE
	void  size           126G        -
	void  capacity       89%         -
	void  altroot        -           default
	void  health         ONLINE      -
	void  guid           10894823139123390159  default
	void  version        28          default
	void  bootfs         void        local
	void  delegation     on          default
	void  autoreplace    off         default
	void  cachefile      -           default
	void  failmode       wait        default
	void  listsnapshots  off         default
	void  autoexpand     on          local
	void  dedupditto     0           default
	void  dedupratio     1.00x       -
	void  free           13.6G       -
	void  allocated      112G        -
	void  readonly       off         -

So, yes please, I could do with some more suggestions.

Thanks :).
