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:
http://docsview.sfbay/app/docs/doc/817-2271/6mhupg6ft?a=view
I think I need to provide a summary of what you can do with
both raidz and mirrored configs since you all had trouble finding
it.
Thanks for the feedback,
Cindy

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.

zpool(1M):
zpool attach [-f] pool device new_device
Attaches new_device to an existing zpool device. The
existing device cannot be part of a raidz configuration.
