FreeBSD 9.1 - setup

We use 2 disks. First for mbr, boot and swap partition. Second for system/data. vtbd2 is our first disk and vtbd3 is a second disk in our example.

1) List available disks:

[root@ ~]# geom disk list

Prepare disk partitioning using GPT schema (help: http://www.wonkity.com/~wblock/docs/html/disksetup.html)

Create GPT schema on both disks:

gpart create -s gpt vtbd2
gpart create -s gpt vtbd3

We need boot,ufs and swap partitions. Boot partition cannot exceed 512kB. Ufs partition on first disk contain just one textfile, 50MB will be enough. Remain space will be used by swap. Second disk is dedicated for system. (-b is used for better allignment/performance).

gpart add -t freebsd-boot -l gpboot -b 40 -s 512K vtbd2
gpart add -t freebsd-ufs -l gpmin -s 50M vtbd2
gpart add -t freebsd-swap -lgpswap  vtbd2
gpart add -t freebsd-ufs -l gproot -b 1M vtbd3

Create FS on desired partitions:

newfs -U /dev/gpt/gpmin
newfs -U /dev/gpt/gproot

Mount boot ufs partition and create textfile with appropriate name and content:

mount /dev/gpt/gpmin /mnt/new/
echo "1:ad(1p1)/boot/loader" > /mnt/new/boot.config

This assume boot from second bios drive, first partition, see: https://www.freebsd.org/cgi/man.cgi?boot%288%29 for explanation

Set "bootme" flag on this "gpmin" partition by invoking gpart (see https://www.freebsd.org/cgi/man.cgi?gpart%288%29):

gpart set -a bootme -i 2 vtbd2

Dowload and restore Fs image to gproot partition:

mount /dev/gpt/gproot /mnt/tmp/
cd /mnt/tmp
[root@ /mnt/tmp]# wget http://www.vizus.cz/sl3b7.gz
[root@ /mnt/tmp]# gzip -dc sl3b7.gz | restore -rvf -

Use restored data and install bootloader to freebsd-boot p.:

[root@ /mnt/tmp]#  gpart bootcode -b /mnt/tmp/boot/pmbr -p /mnt/tmp/boot/gptboot -i 1 vtbd2
bootcode written to vtbd2

Edit fstab in appropriate way to correspond to gpart label.

Nastaveni site: Prejmenujeme vtnet0 na em0 a pak se normalne nastavi, viz example rc.conf:

ifconfig_vtnet0_name="em0"
ifconfig_em0="inet 109.205.76.xx netmask 255.255.255.128"
