Don't know how to fix this as I've not played around with ZFS yet. 
Probably will next time my fileserver needs a capacity bump :). Is it 
possible to persuade ZFS to look for the gpt partition by its 
name(assuming it has one). This seems to be the solution for renumbering 
taken by /etc/fstab for other filesystems. That way it would keep 
finding it regardless of device name.
