How to build FreeNAS from Scratch
Quickstart Guide for Developers and interested User
by Christian Degen aka bubulein [email protected]
Synopsis
After reading this Guide you will know how to Setup a FreeBSD System for compiling FreeNAS from Scratch. This Document will use the current FreeNAS Version based on FreeBSD 7.3. If you want to know more about FreeBSD 7.3 i refer to the FreeBSD 7.3-RELEASE Announcement
You need!
a dedicated PC or Virtual Mashine
a connection to the Internet
8GB Harddiskspace
FreeBSD 7.3 Installation CD ( bootonly or disc1) (see FreeBSD 7.3-RELEASE Announcement)
It isn't necessary to use a dedicated box to compile FreeNAS. In this Guide we will setup our FreeNAS build environment inside a VirtualBox. This virtualisation software can be downloaded for free. Get VirtualBox. Virtualbox is available for Windows, Mac, Linux and OpenSolaris. ( also for FreeBSD
Also You can use VMware or Qemu.
Note on i386 and amd64
For compiling you need to setup a FreeBSD system according to the target architecture. This means if you like to build FreeNAS for amd64 you need to setup a FreeBSD amd64 system. ( same for i386). You can install an i386 system without problems on VirtualBox running on a amd64 Host.
If you want to setup FreeBSD amd64 on an i386 Host you have to use Qemu for emulating amd64. Please follow the Qemu Manual for doing this.
Please read the documentation of your Virtualisation Software for how to setup. Following a short explanation for VirtualBox.
VirtualBox
Installing VirtualBox
Get VirtualBox http://www.virtualbox.org/wiki/Downloads
Follow the Installation instruction acording to your Operatingsystem. Manual
Create a Virtual Machine for FreeBSD
Create “New” Virtual Maschine
Selecte the Name you want to use ( FreeBSD 7.3 - FreeNAS from Scratch)
Operating System: BSD - Version: FreeBSD
Select Memory you want to assign to your VirtualBox ( 256 MB suggested)
Create New Harddrive with atleast 8 GB of Diskspace
Installing FreeBSD 7.3
Now its time to download FreeBSD 7.3 if you have not already done that. There is no better Setup Guide for FreeBSD then the original one from the FreeBSD Handbook.
see: FreeBSD Handbook - Chapter 2 Installing FreeBSD
Preparing FreeBSD
After successful installation there are some steps needed to prepare the system.In this example we install prebuild binaries Let'z Go!!
Connecting via SSH
The easiest way to work with the VirtualBox is connecting via SSH.On Linux and Mac boxes your can use the Terminal to connect via SSH. On Windows you can use a SSH-Client like
Putty which can be downloaded here: PuTTY Download Page
If you don't know the IP of your FreeBSD system type
freenas-dev# ifconfig
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=8<VLAN_MTU>
ether 00:e0:4c:d2:7e:ba
inet 192.168.1.250 netmask 0xffffff00 broadcast 192.168.1.255
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
[...]
Now you can connect via ssh. Use the username you created during setup and the IP of your FreeBSD/Virtual Machine. To become the superuser root type
freenas-dev# su
Why I cannot su to root?
Be sure that your user is member of the group “wheel”. This group is able to become superuser. If not, following command will add your user to group wheel:
freenas-dev# pw usermod YOUR_USERNAME -G wheel
If you don't have a user run
freenas-dev# adduser
Be sure to assign the user to group “wheel”.
Updating FreeBSD
The first step is to update our FreeBSD system.The command
freenas-dev# uname -a
shows you the current FreeBSD version. For example on my Virtual Maschine
FreeBSD freenas-dev.freenas.org 7.3-RELEASE FreeBSD 7.3-RELEASE #0: Sun Mar 21 06:15:01 UTC 2010 [email protected]:/usr/obj/usr/src/sys/GENERIC i386
Start updating your FreeBSD with
freenas-dev# freebsd-update fetch install
This will fetch and install all updates.After a reboot with
freenas-dev# reboot
The command
freenas-dev# uname -a
Should show you that you updated FreeBSD. see the -p1 in my example. This means we updated to “patchlevel 1”.
freenas-dev# uname -a
FreeBSD freenas-dev.freenas.org 7.3-RELEASE-p1 FreeBSD 7.3-RELEASE-p1 #0: Wed May 26 04:29:05 UTC 2010 [email protected]:/usr/obj/usr/src/sys/GENERIC i386Installing necessary applications
Following the commands you should execute to install the applications we need for compiling FreeNAS from scratch.
If you like to install them prebuild ( the easiest way) use:
freenas-dev# pkg_add -r subversion /
pkg_add -r cdrtools /
pkg_add -r portupgrade /
pkg_add -r php5 /
pkg_add -r perl /
pkg_add -r ruby /
pkg_add -r m4 /
pkg_add -r bison /
pkg_add -r xproto /
pkg_add -r nano /
pkg_add -r bash /
pkg_add -r cvsup-without-gui
Depending on your shell execute “rehash” to publish new commands
Fetching the ports-tree
Now we fetch the ports-tree. The ports-tree conatains all information we need to compile an application from source.
freenas-dev# portsnap fetch extract
This takes a few minutes. After fetching and extracting you find everything under/usr/ports. For more information about the ports-tree see Using the Ports Collection
If you later want to update the ports-tree you can use
freenas-dev# portsnap update
Also cvsup can be used - more on this topic later.
Downloading FreeBSD Sourcecode
For downloading the FreeBSD sources we use cvsup which we have already installed. Cvsup can also be used for updating the ports-tree. Do:
freenas-dev# cp /usr/share/examples/cvsup/ports-supfile /etc
freenas-dev# cp /usr/share/examples/cvsup/standard-supfile /etc/source-supfile
Then use your favorite editor ( nano, ee, vi) to change following lines in the files we copied above:
freenas-dev# ee /etc/source-supfile
from:
*default host=CHANGE_THIS.FreeBSD.org
to:
*default host=cvsup2.de.FreeBSD.org
see http://www.freebsd.org/doc/handbook/mirrors.html for a mirror next to you.
After editing the files run:
freenas-dev# cvsup -L 2 -g /etc/source-supfile
freenas-dev# cvsup -L 2 -g /etc/ports-supfilefor updating. ( ports-tree should be already uptodate)
Updating installed Ports
Earlier in this Guide we have installed the applications we need as prebuild binaries.Sometimes these binaries are not 100% uptodate. To avoid this you can now run
portupgrade -av
This well use your ports-tree to compile this applications again with the most actual source from the ports-tree. While updating “portupgrade” ask you some options you ould use for building the applications from source. Its ok to use the default settings.
To avoid building X11 ( Graphical Desktop related) we create or edit/etc/make.conf and add the line
WITHOUT_X11=yes
Perhaps this the right time to create a Snapshot of your system. See The manual of your Virtual Machine for a “HowTo”
For VirtualBox see: First steps - Snapshots
Building FreeNAS
Setup FreeNAS build environment
Now we are going to setup the necessary directories and download the FreeNAS SVN.Developers use Subversion to maintain current and historical versions of files such as source code, web pages, and documentation.see: Apache Subversion on Wikipedia.org
Then i will guide you step by step through the interactive buildscript.
Getting FreeNAS from svn
Everything is build under/usr/local/freenas, so we create the directory and checkout the svn code.
freenas-dev# mkdir /usr/local/freenas
freenas-dev# cd /usr/local/freenas/
freenas-dev# svn co https://freenas.svn.sourceforge.net/svnroot/freenas/branches/0.7 svn
Error validating server certificate for 'https://freenas.svn.sourceforge.net:443':
- The certificate is not issued by a trusted authority.//
Use the fingerprint to validate the certificate manually!
Certificate information:
- Hostname: *.svn.sourceforge.net
- Valid: from Mon, 04 Jan 2010 14:21:55 GMT until Sat, 05 Feb 2011 09:03:23 GMT
- Issuer: Equifax Secure Certificate Authority, Equifax, US
- Fingerprint: ea:d1:3e:01:cc:16:e9:9b:c2:ab:4b:0c:cc:26:5f:25:78:ea:89:b4
(R)eject, accept (t)emporarily or accept (p)ermanently?
Here you can answer with (p), cause this isn't a error. You just don't have downloaded the certificate.
Compiling FreeNAS
To start the FreeNAS build script run
freenas-dev# /usr/local/freenas/svn/build/make.sh
The first screen appears and we can start
Welcome to the FreeNAS build environment.
Menu:
1 - Update the sources to CURRENT
2 - Build system from scratch
10 - Create 'Embedded' (IMG) file (rawrite to CF/USB/DD)
11 - Create 'LiveCD' (ISO) file
12 - Create 'LiveCD' (ISO) file without 'Embedded' file
13 - Create 'Full' (TGZ) update file
* - Quit
>
For a first run you should go through all steps. Following i will guide you from here to your first FreeNAS LiveCD and embedded image.
Everything should be uptodate, but we do this step again just to illustrate later builds.
Select 1 - Update the sources to CURRENT
and if everything work as expected the answer should be
Checked out revision 5235.
=> Successful
Seclect 2 - Build system from scratch
Bulding system from scratch
Menu:
1 - Update source tree and ports collection
2 - Create filesystem structure

If unsure keep all settings as is. This will compile the same Kernel who is released with the official FreeNAS builds!Now your System need some time to build the Kernel.
Now you are back on the previous screen, and we start building the world
Select 4 - Building World
This will copy all necessary files from the build system the your FreeNAS environment.
Now we start building the Ports.
Select 5 - Build ports
And select “build”.Then you can select which ports you like to build. Select “ALL” for a standard FreeNAS build.

Select 5 - Build ports
Select this option again, but now choose “install” instead of “build”
install Install ports
This will install all your prebuild ports along with needed files from you base FreeBSD system.
Select 6 - Build bootloader
To build and install the bootloader.
Select 7 - Add necessary libraries
Should be self explained.
Select 8 - Modify file permissions
The last step will set the correct permissions for you FreeNAS files.
Now quit with * and you are back on the previous screen.
Welcome to the FreeNAS build environment.
Menu:
1 - Update the sources to CURRENT
2 - Build system from scratch
10 - Create 'Embedded' (IMG) file (rawrite to CF/USB/DD)
11 - Create 'LiveCD' (ISO) file
12 - Create 'LiveCD' (ISO) file without 'Embedded' file
13 - Create 'Full' (TGZ) update file
* - Quit
Now the last step in our build process. Choose one of the option from 10 - 13 to create the final FreeNAS ISO-Image or embedded file.
In this example i choose option 11 for creating a LiveCD.
Thats all
After a successful build you find your Ready to Use FreeNAS ISO and/or IMG in/usr/local/freenas
[root@harry /]# ls /usr/local/freenas
FreeNAS-i386-0.7.2.5234.checksum builds
FreeNAS-i386-LiveCD-0.7.2.5234.iso rootfs
FreeNAS-i386-embedded-0.7.2.5234.img svn
bootloader work
Hopefully this document helps you to build your own FreeNAS from scratch.
