> So... the smaller size won't mess things up... If by smaller size you mean smaller size of existing drives/partitions, then growing zpools by replacing smaller vdevs with larger ones is supported and works. What isn't supported is basically everything else: - you can't change number of raid columns (add/remove vdevs from raid) - you can't change number of parity columns (raidz1->2 or 3) - you can't change vdevs to smaller ones, even if pool's free space would permit that. Good news is these features are planned/being worked on. If you can attach more drives to your system without disconnecting existing drives, then you can grow your pool pretty much risk-free.
