It is so easy since you just add more of the same type to the pool.
For raidz stuff they actually recommend no more than 9 disks in each
raidz for best performance so you would just add multiple sets of raidz
after the first raidz is "created". Check BigAdmin zpool tips.

I have read that no more disks can be added to an already created RAIDZ/RAIDZ2
volume, is that true? Any workaround to expande such a pool with more storage?
