No, I just assumed, incorrectly it seems, that zfs had a command structure similar to ext2-3-4. The above link says you can't without a full backup, repartition and restore. So I stand corrected. And better educated. And yes, I have used gparted to adjust ext3-4 systems. Its a rather arduous, time consuming task but it worked. And its dangerous to do on a live filesystem so I boot gparted from optical media. But the size of my data has not grown as fast as the size of a commodity drive, a 1T drive is now $50 in my mailbox, so space is not, and has not been a problem for me for 4 or 5 years.
