Description

Almost at the bottom of this section: http://doc.freenas.org/9.3/freenas_intro.html#zfs-primer

It says:
It is recommended to use drives of equal sizes. While ZFS can create a pool using disks of differing sizes, the capacity will be limited by the size of the smallest disk.

I think this should be:
It is recommended to use drives of equal sizes in a vdev. While ZFS can create a vdev using disks of differing sizes, the capacity will be limited by the size of the smallest disk.

My understanding is that a pool is made up of vdevs and not disks, so I don't see how it makes sense to talk about disks in the context of a pool.

I also base this on the following articles about ZFS:

There's a lot of contradicting information about ZFS online, so I think it is important to correct this.

Thanks for a great product!
