I'm still developing my new system, I'm a newbie on FreeNAS so some confusion. I'm thinking about which configuration use and I'm oriented to a raid 1+0. So i think to create 2 vdevs each with 2 disks mirrored and join them together into one zpool. Here come my problem, maybe I use 4 drive each 2tb so 4 tb space available. When this space was over can i change only 2 disk from the same vdev (one at time) and expand my zpool available space? Ie. I change 2 disk from vdev1, with 2 hdd 3tb each, can I expand the zpool so to use the 1tb free space?
Thank you
