No one has said that you can't increase the size of a zpool. What can't
be increased is the size of a RAID-Z vdev (except by increasing the size
of all of the components of the RAID-Z). You have created additional
RAID-Z vdevs and added them to the pool.
If following is nonsense, please bear with
Malachi,
The section on adding devices to a ZFS storage pool in the ZFS Admin
guide, here, provides an example of adding to a raidz configuration:

I think I need to provide a summary of what you can do with
both raidz and mirrored
Here's the correct link:

The same example exists on page 52 of the 817-2271 PDF posted on
the opensolaris.../zfs/documentation page.

You cannot add 1 drive at a time to a raid-z or raid-2z. You need to add the
same number of disks that were used per stripe.. So, if you start with 5 disks,
you would have to add 5 more in the future to add disk space. There is also a
method of swapping each disk one at a time with a larger
One option is you can replace all the existing devices in a raidz vdev with
larger devices, and then export/import the pool and the vdev will grow in size.
I agree that you simply can't add a single device to grow a raidz vdev.

You cannot add drives to a raid-z or raid-z2, period.

Hmmm... I definitely missed this one... I thought the documentation said
that using zpool attach would add a new drive to the existing raidz(2) and
then it would start resilvering...

Yeah, I am not sure what docs I was originally looking at...
Although we may want to ensure that the ZFS Admin Guide is a bit more clear
on the matter:
Additional disks can be added similarly to a RAID-Z configuration.

The man page is a little unclear. zpool attach is for adding drives to

Yeah, what I had been hoping (and to be honest kinda counting on) was that I
could do a raidz2 across the 7x250GB drives (which is not actually going to
happen since I am going to mirror 2 of them for boot) and then just add
another 250GB drive when more space is needed.
Realistically, I am not
Since no one seems to believe that you can expand a raidz pool, I have attached
the following output from solaris 11/06 showing me doing just that. The first
expanision is with like sized disks, and the second expansion is with larger
disks. I realize that the documentation only has examples
