Ever wished to have an energy-efficient NAS with just a Raspberry Pi, and an Hard Drive? Just follow these steps to setup your own Samba share with automatic spindown. Short on time? Skip to TL;DR section.
Let’s start by plugging our drive to the Raspberry Pi and adding the partition to fstab with
sudo nano /etc/fstab (just add the following line at the end of the config file). We use the
noauto flag to avoid our Pi freezing if drive is not connected at boot.
1 UUID=8776d0a3-875a-47e9-8f26-33b261fb834a /media/nasdisk ext4 rw,defaults,noauto 0 0
NOTE: you can find your drive’s UUID with
blkid /dev/sda1(replacing /dev/sda1 with your partition).
Since we used the
noauto flag, the system won’t mount this drive. We have to mount this drive ourselves. Since we run the command in the background with
& the Raspberry Pi will still boot without delay even when the drive is not connected.
Open your crontab configuration with
sudo crontab -e and, at the end of the file, add the following lines.
1 2 PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin @reboot mount /media/nasdisk >/dev/null 2>&1 &
NOTE: if you don’t want to add the
PATHvariable to your crontab you can use full path to the binaries you run (find full path of
You should also manually create the mountpoint directory to avoid unexpected surprises.
1 sudo mkdir /media/nasdisk
Since we don’t want to waste power, we spin down the drive after 15 minutes of inactivity. The following line does the trick and it must be added to crontab configuration.
1 @reboot hdparm -B127 -S180 /dev/disk/by-id/ata-ST2000DM001-1ER164_W4Z06AY0 >/dev/null 2>&1 &
NOTE: you can find your drive’s ID by manually checking the output of
ls -l /dev/disk/by-id/.
Reboot and ensure your drive is accessible at /media/nasdisk. You might also want to leave the Raspberry Pi unused for 15 minutes and check that the drive actually spins down.
Install Samba and create a new user specific for your share and give it a Samba password (Samba password doesn’t have to be the same as the UNIX password).
1 2 3 sudo apt-get install samba sudo useradd sambauser sudo smbpasswd -a sambauser
Then configure your share with
sudo nano /etc/samba/smb.conf; append the following lines.
1 2 3 4 [sharename] path = /media/nasdisk read only = no valid users = sambauser
Note: if you want to customize your share you can find more info about smb.conf file on on it’s manpage.
Do not forget to restart Samba service with
sudo service smbd restart.
Share will be accessible at \\raspberrypi\sharename\ (if it doesn’t work, replace raspberrypi with your Raspberry Pi’s IP address).
Thanks for reading, I hope this guide will be useful to you! Do not forget to leave your opinion in the section below.
The following sample commands will result in mounting /dev/sda6 in /media/nasdisk on boot and sharing it at \\raspberrypi\shared\, with the user sambauser and password mypassword. Spinning down the drive ata-ST2000DM001-1ER164_W4Z06AY0 after 15 minutes of inactivity.
WARNING: do not forget to customize the
driveidvariables. Besides that, if you are on Raspbian, you can just copy/paste this commands and everything will magically work!
