Having recently returned to FreeBSD from a 4 year stint with Gentoo, I decided to switch most of my systems back to FreeBSD (a few still run Gentoo). I've been using FreeBSD since 1998 and it proved to be a solid OS back then while I was a Radioman in the Navy (operating on a small P166 server in the ships library). I'm glad things are better now that ZFS is out.
Enough about me, let's get down to getting ZFS working on your Sparc64-based system.
1. Build your disk partitions. You can adjust the sizes to your taste.
2. Load the appropriate modules to get ZFS working.
3. Create the ZFS pool and adjust checksum and compression settings. I would suggest keeping the checksum settings. If you want to change the compression or disable it altogether, go ahead.
4. Mount your UFS /bootdir partition.
5. Extract the .txz files onto your system.
*NOTE* I have the /usr/ports on a dedicated server due to having several FreeBSD servers running. That way I don't waste valuable space. If you want to add the ports collection, just add ports.txz after doc.txz below.
6. Chroot into your system so you can change some of the system files.
7. Edit your /etc/fstab to include these lines:
8. Create a password for your system, change your timezone, and create aliases for the mail system.
9. Leave the chroot.
10. Unmount the entire filesystem and create mountpoints for the ZFS filesystem.
11. Reboot the system and you're done with the initial install.
This entire script took a SunFire V100 about 10 minutes to install FreeBSD 9.0-RELEASE on a ZFS filesystem with lzjb compression. Not bad for an UltraSPARC IIe.
Enough about me, let's get down to getting ZFS working on your Sparc64-based system.
1. Build your disk partitions. You can adjust the sizes to your taste.
Code:
sunlabel -B ada0
gpart destroy -F ada0
gpart create -s vtoc8 ada0
gpart add -s 192M -t freebsd-ufs /dev/ada0
gpart add -s 1G -t freebsd-swap /dev/ada0
gpart add -t freebsd-zfs /dev/ada02. Load the appropriate modules to get ZFS working.
Code:
kldload /boot/kernel/opensolaris.ko
kldload /boot/kernel/zfs.ko3. Create the ZFS pool and adjust checksum and compression settings. I would suggest keeping the checksum settings. If you want to change the compression or disable it altogether, go ahead.
Code:
zpool create -f -m /mnt zroot /dev/ada0d
zpool set bootfs=zroot zroot
zfs set checksum=fletcher4 zroot
zfs set compression=lzjb zroot
zfs create zroot/usr
zfs create zroot/var
zfs create zroot/tmp
zfs create zroot/data
chmod 1777 /mnt/tmp
zpool export zroot
zpool import -o cachefile=/tmp/zpool.cache zroot4. Mount your UFS /bootdir partition.
Code:
mkdir /mnt/bootdir
newfs -m 0 /dev/ada0a
mount /dev/ada0a /mnt/bootdir5. Extract the .txz files onto your system.
*NOTE* I have the /usr/ports on a dedicated server due to having several FreeBSD servers running. That way I don't waste valuable space. If you want to add the ports collection, just add ports.txz after doc.txz below.
Code:
cd /usr/freebsd-dist
export DESTDIR=/mnt
for file in base.txz kernel.txz doc.txz games.txz ; do (cat $file | tar --unlink -xpJf - -C ${DESTDIR:-/}) ; done
cp /tmp/zpool.cache /mnt/boot/zfs/zpool.cache6. Chroot into your system so you can change some of the system files.
Code:
chroot /mnt
Code:
echo 'zfs_enable="YES"' > /etc/rc.conf
echo 'hostname="server.example.lan"' >> /etc/rc.conf
echo 'ifconfig_dc0="DHCP"' >> /etc/rc.conf
echo 'sshd_enable="YES"' >> /etc/rc.conf
echo 'zfs_load="YES"' > /boot/loader.conf
echo 'vfs.root.mountfrom="zfs:zroot"' >> /boot/loader.conf
echo 'vfs.zfs.prefetch_disable="1"' >> /boot/loader.conf
echo 'console="ofw"' >> /boot/loader.conf
mv boot bootdir/
ln -s bootdir/boot /boot
chflags -h sunlink /boot7. Edit your /etc/fstab to include these lines:
Code:
# Device Mountpoint FStype Options Dump Pass#
/dev/ada0a /bootdir ufs rw 0 0
/dev/ada0b none swap sw 0 08. Create a password for your system, change your timezone, and create aliases for the mail system.
Code:
passwd
Code:
tzsetup
Code:
cd /etc/mail
make aliases9. Leave the chroot.
Code:
exit10. Unmount the entire filesystem and create mountpoints for the ZFS filesystem.
Code:
cd
umount /mnt/bootdir
zfs umount -a
zfs set mountpoint=legacy zroot
zfs set mountpoint=/tmp zroot/tmp
zfs set mountpoint=/var zroot/var
zfs set mountpoint=/usr zroot/usr
zfs set mountpoint=/data zroot/data11. Reboot the system and you're done with the initial install.
