Hi Tim,
In a pool with mixed disk sizes, ZFS can use only the amount of disk
space that is equal to the smallest disk and spares aren't included in
pool size until they are used.
In your RAIDZ-2 pool, this is equivalent to 10 500 GB disks, which
should be about 5 TBs.
I think you are running a current Nevada release. Did you try setting
the autoexpand property to on?
See the example below, I created a RAIDZ-2 pool with 2 68 GB disks and 1
136 GB disk. I replaced the 2 68 GB disks with 2 136 GB disks and set
autoexpand to on. My pool space increased from 204 GB to 410 GB on
Nevada, build 127, which sounds about right. The autoexpand property
integrated into build 117.

So I've finally finished swapping out my old 300GB drives. The end
result is one large raidz2 pool. 10+2 with one hot spare.
The drives are:
7x500GB
4x1TB
2x1.5TB
One of the 1.5TB is the hot spare. zpool list is still showing capacity
of 3.25TB (the 1TB drives replaced 300GB drives). I've tried exporting
and importing the pool, and it doesn't make a difference.
