Add drives on RAIDZ2 to expand the total capacity is possible ?

[GioMBG]

Hi All,
Hoping to find You ALL Well.
I see here that mybe extending-a-pool is just possible but as a newbie I would like to be sure 100 %
so, for example, from a set up of 6 HDs I will have to add another 2 HDs ( same size ) on my RAIDZ2 ( not encrypted ) :
It will be possible to expand from 6 to 8 Disks my existent RAIDZ2 without move all saved data ?
thanks !

After a vdev is created, more drives cannot be added to that vdev. However, a new vdev can be striped with another of the same type of existing vdev to increase the overall size of the pool.

You can add another RAIDZ2 vdev of 6 drives, but you cannot add 2 drives to your existing RAIDZ2 vdev.
