zero or more pools/volumes, each composed of one or more vdevs, each composed of one or more HDs.
You can add pools at any time, and you can add vdevs to pools at any time.
You can't add/remove HDs to/from a RaidZ[123] vdev.
And you can't remove vdevs from a pool.
Is that to say that if for instance I have a vdev made up of 4 2TB drives, that I can't upgrade the drives to a bigger size? I could presumably replace a bad 2TB with another drive, but not expand the vdev, either by enlarging the drives or adding more drive to the vdev?
That would seem to make a person not want to have more than one vdev per pool to avoid inherent limitations? That would then mean you couldn't have one large volume?
Thanks!
