Greeting, I had a bit time, free slice on the disk with MBR and the desire to play with the new installation of FreeBSD 9.0-RC1 . Below is just a simple example ; there will be one ZFS filesystem on /, no swap, no keys for GELI, passphrase only. Nevertheless, I decided to share the method which can be used in different setups and configurations.

My setup consists of: ada0 - hard drive ada0s1 - slice will be used for boot 1G ada0s2 - slice will be used for swap 4G ada0s3 - slice will be used for ZFS 50G

1. Boot with your FreeBSD install disk and choose “Live CD” when prompted, login as root, no password is required. 2. This step is optional but it's a good idea. Code:

dd if=/dev/urandom of=/dev/ada0s1 dd if=/dev/urandom of=/dev/ada0s3

3. bsdlabeling: Code:

bsdlabel -w /dev/ada0s3

4. Loading the required modules: Code:

kldload geom_eli zfs

5. Labeling partition: Code:

glabel label zrpool /dev/ada0s1a

6. Initiation and attachment GELI: Code:

geli init -b /dev/label/zrpool geli attach /dev/label/zrpool

7. Creation ZFS pool and FS: Code:

zpool create -O mountpoint=/mnt -O canmount=off zrpool /dev/label/zrpool.eli zfs create -o mountpoint=legacy zrpool/FreeBSD

8. Installation FreeBSD: Code:

mount -t zfs zrpool/FreeBSD /mnt tar -xf /usr/freebsd-dist/base.txz -C /mnt tar -xf /usr/freebsd-dist/kernel.txz -C /mnt

You can select and install something else, please take a look at /usr/freebsd-dist/ 9. ada0s1, preparation: Code:

bsdlabel -B -v /dev/ada0s1 newfs /dev/ada0s1a

10. Copying /boot to ada0s1: Code:

mkdir /tmp/boot mount /dev/ada0s1 /tmp/boot cp -Rp /mnt/boot /tmp/boot/

11. Creation fstab and loader.conf: a) create /tmp/usbboot/boot/loader.conf and add the following lines: Code:

geom_eli_load="YES" zfs_load="YES"

  1. aesni_load="YES" # option see man aesni

vfs.root.mountfrom="zfs:zrpool/FreeBSD"

b) create /mnt/etc/fstab: Code:

  1. cat > /mnt/etc/fstab

zrpool/FreeBSD / zfs rw 0 0 ^D

12. Generation and recording zpool.cache to USB stick: Code:

zpool export zrpool zpool import -o cachefile=/tmp/usbboot/boot/zfs/zpool.cache zrpool

13. Change pool mountpoint to / Code:

zfs set mountpoint=/ zrpool

14. Finish. Code:

shutdown -r now
