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-RELEASE .
Below is just a simple example ; there will be one ZFS filesystem on /, 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
ada0s1a- slice will be used for swap 4G
ada0s1b - slice will be used for boot 1G
ada0s1d - slice will be used for ZFS  51G (crypto)
gpart create -s MBR ada0
gpart add -t freebsd -s 56G ada0
gpart create -s BSD ada0s1
gpart add -t freebsd-swap -s 4G ada0s1
gpart add -t freebsd-ufs -s 1G ada0s1
gpart add -t freebsd-zfs ada0s1
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/ada0s1b
dd if=/dev/urandom of=/dev/ada0p4
3. bsdlabeling:
Code:
bsdlabel -w /dev/ada0s1d
4. Loading the required modules:
Code:
kldload geom_eli zfs
5. Labeling partition:
Code:
glabel label zrpool /dev/ada0s1d
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/ada0p3
newfs /dev/ada0s3
10. Copying /boot to ada0p3:
Code:
mkdir /tmp/boot
mount /dev/ada0p3 /tmp/boot
cp -Rp /mnt/boot /tmp/boot/
11. Creation fstab and loader.conf:
a) create /tmp/boot/boot/loader.conf and add the following lines:
Code:
geom_eli_load="YES"
zfs_load="YES"
# aesni_load="YES"  # option see man aesni
vfs.root.mountfrom="zfs:zrpool/FreeBSD"
b) create /mnt/etc/fstab:
Code:
# cat > /mnt/etc/fstab
/dev/ada0p4 / zfs rw 0 0
/dev/ada0p3    /boot ufs rw 0 0
/dev/ada0p2  swap sw 0 0
12. Generation and recording zpool.cache to /boot stick:
Code:
zpool export zrpool
zpool import -o cachefile=/tmp/boot/boot/zfs/zpool.cache zrpool
13. Change pool mountpoint to /
Code:
zfs set mountpoint=/ zrpool
14. Finish.
Code:
shutdown -r now
