Hello,
I want to build a new nas and i'm still figuring out which pool type I want to use. I could buy 3 disks first and configure it as a Z1 array. Then, when needed, upgrade with another 3-disk Z1 array (Stripe over two Z1 arrays).
The other option i'm debating is to build a 4 disk Z2 array and eventually I expand with 2 extra disks.
In order to decide I need to understand what happens when you expand a Z1 or Z2 array.
I've browsed the internet for an answer but I still don't understand.
Lets say i've got that 4 disk Z2 array and expand it with 2 identical disks. Does ZFS integrate the extra storage or is it still the old Z2 array with a "raid0" like stripe to the other disk?
I know ZFS only rearranges the data when it's written again so the old data will stay where it was before the expand.
