I want the ability to add/remove disks to an array, and I'm still unsure of the stability of zfs as a whole. I'm looking for an easy way to resize and manage disks that are greater than 2 terabytes. If I have a single block device, /dev/da0, on my system that is represented by a zfs disk vdev, and the size of this block device grows (because the underlying hardware raid expands), will zfs correctly expand? And will it correctly expand in place?
