Hello all, I am getting ready to start allocating storage for my FreeNAS server and need some feedback from ya'll on how to achieve my goals.
I am starting off with 4 x 2TB WD Red Drives. My goal is to have a RaidZ2 so that I have a two disk fault tolerant storage. I would like to be able to expand the volume size in a year from now without having to destroy the whole storage volume and need some help on how to setup the initial volume with vdevs.
I have read the document by cyberjock which outlines very nicely the concepts of ZFS but how to create this in the GUI and if I understand correctly the concept is what I need assistance with.
If I setup my initial ZPool or Volume as below it would be a RaidZ2 Volume with 4 x 2TB drives in a VDEV giving me 4 TB usable space. If in a year from now when I want to add more space am I limited to the number of drives I can put in the new VDEV to add to the Pool? Example could I add 2 x 2TB drives or would it have to be 4 x 2TB drives? Once I added the appropriate number of drives I would create a new VDEV and the add that VDEV to the orignal ZPool?
Can some one please confirm if my understanding is right and that what I am doing will allow for future expansion?
