RaspiNAS – DIY nas with a Raspberry

After more than one year with my NAS build over an ALIX, I bought a Raspberry pi 2 and I want to check if the “USB POWER BUG” is resolved now.

I don’t need an high speed NAS so the speed issue with the shared PCI link between USB hub and network adapter is not so important.

Advantages of a Raspberry pi 2 setup are:

  • Less power consumption: raspberry drain half the power of an Alix card
  • Flexibility: 4 USB ports instead of 2
  • Smaller: Raspberry Pi 2 is smaller than Alix board

So this is a copy&paste from my previous post, adapted for the new environment

Install Raspbian lite

Go to Raspbian download page and download the lite version

Install VIM
# apt-get install vim
Add new user
# useradd -m -s /bin/bash sarbyn
# passwd sarbyn
Add user to sudo
# visudo --- add user
Install NTFS-3G
# apt-get install ntfs-3g
Fstab and volumes
# mkdir /mnt/TimeMachine
# mkdir /mnt/MUSIC
# chown sarbyn:sarbyn /mnt/MUSIC
# chown sarbyn:sarbyn /mnt/TimeMachine

UUID=206606FF6606D606 /mnt/MUSIC ntfs-3g   rw,defaults     0       0
UUID=03c90579-88f0-4478-ae8d-adc64972a07d /mnt/TimeMachine ext4 defaults 0 0
# apt-get install samba samba-common-bin
# service samba stop
# mv /var/lib/samba /var/tmp/samba
# ln -s /var/tmp/samba /var/lib/samba
# smbpasswd -a sarbyn
path = /mnt
read only = Yes
guest only = Yes
guest ok = Yes

path = /mnt
read only = No
valid user = sarbyn
browseable = yes
writable = yes
$ mkdir .ssh
$ chmod 0700 .ssh/
$ cd .ssh
$ ls
$ vim authorized_keys
$ chmod 600 authorized_keys

Disable root login and plaintext login in /etc/ssh/sshd_config file

# apt-get install transmission-daemon
# service transmission-daemon start
FIX cracklib config

I don’t know if it is required with new Jessie debian version…but I’ve repeated it

# apt-get install cracklib-runtime
# create-cracklib-dict /usr/share/dict/*

root@voyage:/var/cache/cracklib# ls -la
-rw-r--r-- 1 root root 1024 Oct 4 13:28 cracklib_dict.hwm
-rw-r--r-- 1 root root 16 Oct 4 13:28 cracklib_dict.pwd
-rw-r--r-- 1 root root 16 Oct 4 13:28 cracklib_dict.pwi
-rw-r--r-- 1 root root 65 Oct 4 13:17 src-dicts

root@voyage:/var/cache/cracklib# ls -la
-rw-r--r-- 1 root root 1024 Oct 7 22:46 cracklib_dict.hwm

The older version of netatalk are VERY…VERY unstable. Download the sources from Netatalk site and follow —> this tutorial <—

# apt-get install build-essential libevent-dev libssl-dev libgcrypt11-dev libkrb5-dev libpam0g-dev libwrap0-dev libdb-dev libtdb-dev libmysqlclient-dev avahi-daemon libavahi-client-dev libacl1-dev libldap2-dev libcrack2-dev systemtap-sdt-dev libdbus-1-dev libdbus-glib-1-dev libglib2.0-dev tracker libtracker-sparql-1.0-dev libtracker-miner-1.0-dev 
# apt-get install avahi-daemon

# insserv avahi-daemon
# insserv netatalk
# /etc/init.d/avahi-daemon start
# /etc/init.d/netatalk start

Edit “/usr/local/etc/afp.conf”.

; Global server settings
uam list = uams_dhx.so,uams_dhx2.so
set password = yes

    path = /mnt/MUSIC

    path = /mnt/TimeMachine
    time machine = yes

Add user to Netatalk (using the SHORT password)

# afppasswd -an sarbyn

The NTFS volume does not mount at boot, so add some lines on /etc/rc.local

# vim /etc/rc.local

service transmission-daemon stop
mount -a
swapon /mnt/MUSIC/swapfile
service transmission-daemon start

# chmod +x /etc/rc.local
NOIP client
# wget http://www.no-ip.com/client/linux/noip-duc-linux.tar.gz
# tar xzf noip-duc-linux.tar.gz
# cd no-ip-2.1.9
# make
# make install
# sudo noip2 -U 60
Install RPI monitor

Rpi monitor is a small web application that shows usage statistics of a raspberry pi board. Install rpi monitor following this link
Configure /etc/rpimonitor/storage.conf in order to setup storage monitoring and edit the /etc/rpimonitor/data.conf in order to include the storage.conf entry.

Optional – MiniDLNA support

If you need miniDLNA support follow this link

Final step – do a MicroSD backup

Now is all setted up but it’s better to do a MicroSD backup using dd

# dd if=DISK of=raspinas-backup.img bs=1m

Rsync : daily backup

This is a simple reminder.
I’m doing a lot of changes in my NAS and my “domotic” RaspBerry (One of these days I’m going to write down something about the Raspberry project) and I need a simple backup solution for a running linux machine.

It’s very simple, use this script and add to /etc/cron.daily

rsync -aAXv --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} --delete /* /path/to/backup/folder
