I was disappointed by the lack of RAIDZ2 resize when I built my ZFS fileserver, but it turns out that my data growth is slower than the growth in size of HDD's, so I just replace the drives every 4 or 5 years and copy the data over. Now drives are so big that I might just go with mirroring instead of RAIDZ2
