Thanks for the responses guys. It looks like I'll probably use RaidZ2 with 8
drives. The write bandwidth isn't that great as it'll be a hundred gigs every
couple weeks but in a bulk load type of environment. So, not a major issue.

Hi Michelle,
Your previous mail about the disk label reverting to EFI makes me wonder
whether you used the format -e option to relabel the disk, but your disk
label below looks fine.
This also might be a known bug (6419310), whose workaround is to use the
-f option to zpool attach.
An interim
Personally, I'd go with 4x raidz2 vdevs, each with 6 drives. You may not get
as much raw storage space, but you can lose up to 2 drives per vdev, and you'll
get more IOPS than with a 3x vdev setup.
Our current 24-drive storage servers use the 3x raidz2 vdevs with 8 drives in
each. Performance

It looks like there is not a free slot for a hot spare? If that is the case,
then it is one more factor to push towards raidz2, as you will need time to
remove the failed disk and insert a new one. During that time you don't want to
be left unprotected.
