Iris is a Kimsufi KS 2G dedicated server hosted at OVH, running an Atom N2800 (1.86GHz, 2 cores) with 2GB RAM and a 500GB disk.

The naming

In Greek mythology, Iris is the personification of the rainbow and messenger of the gods. She is also known as one of the goddesses of the sea and the sky. Iris links the gods to humanity. She travels with the speed of wind from one end of the world to the other, and into the depths of the sea and the underworld.


Iris runs FreeBSD 9.1-RELEASE, installed from scratch on a ZFS root via the rescue mode. I used the tarball from mfsbsd and their script zfsinstall.

# mdmfs -M -S -o async -s 1000m md4 /tmp/
# cd /tmp
# wget
# wget --no-check-certificate
# chmod +x zfsinstall
# bsdtar xf mfsbsd-se-9.1-RELEASE-p2-amd64.iso 9.1-RELEASE-p2-amd64.tar.xz
# gpart destroy -F ada0
# ./zfsinstall -d ada0 -t 9.1-RELEASE-p2-amd64.tar.xz -s 4G -c -4

This fails creating the zpool.cache, but that problem is “solved” by rebooting into the rescue mode again and importing the tank without specifying an altroot.
