This isn’t much of an article, the information here is quite readily available elsewhere, but I’m just documenting how I set up a Raspeberry Pi 3 with a removable hard drive to work as a DIY NAS at home. Just so I can come back to it if I have to do it again.
Note: was fun and all, and it does work, but not very smoothly, and it’s a bit of a pain. I should pay Dropbox | Google | Amazon and be done with it. Anyway… [hits publish]
Set up the Pi (no monitor) from a Mac
Download the latest Raspbian release at http://downloads.raspberrypi.org/raspbian_latest
unzip the file to get a
Insert micro-SD card in plastic adapter into the SD slot for my mac
spot the mounted SD card from the command line:
$ df -h Filesystem Size Used Avail Capacity iused ifree %iused Mounted on [...] /dev/disks3 xxGi xGi xxGi xx% xxxxxx xxxxxxx 0% /Volumes/MYCARD
My SD Card is on /dev/disks3, now (substituting the actual number to the 3 given here) I can transfer the .img to the card.
$ sudo diskutil unmount /dev/disk3s1 # unmount (but do not eject) $ sudo dd bs=1m if=./whatever-version-raspbian.img of=/dev/rdisk3 # copy on disk 3 (substitute proper number)
add an empty file on the SD Card, simply called
eject the card:
$ sudo diskutil eject /dev/rdisk3
transfer the SD card to the pi, plug it with an ethernet cable to the router, and power it up.
log in to the router’s admin page in your browser. For me it’s at http://10.0.0.1/. You should be able to see your Pi in the list of attached devices, with its IP address and network name, say
10.0.0.6 / raspberrypi
ssh to the pi with
ssh email@example.com the default
raspberrypassword (good idea to change it)
complete the install process :
expand the filesystemand reboot when it’s done
- connect again with ssh and do some house cleaning:
sudo apt-get updateand
sudo apt-get upgrade
Let the Pi share its screen:
pi@raspberrypi ~ $ sudo apt-get tightvncserver # download VNC server pi@raspberrypi ~ $ tightvncserver # start VNC server pi@raspberrypi ~ $ vncserver :0 -geometry 1920x1080 -depth 24 # start VNC session
Access the screen on the Mac: in Finder: Go > Connect To Server >
vnc://10.0.0.6:5901and provide the pi’s password.
Your Pi is ready and you should see a nice window within your mac.
Basically follow https://www.raspberrypi.org/documentation/configuration/external-storage.md, id est
sudo lsblk -o UUID,NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL,MODEL # identify the name of the disk partition that points to your HDD, e.g. sda1. sudo blkid # get the location of the disk partition e.g. /dev/sda1. Also take not of the drive's UUID, which you'll need later. Should look something like 810A-1B1D sudo mkdir /mnt/PIHDD sudo mount /dev/sda1 /mnt/PIHDD
But you also want the Pi to automatically mount the disk on boot, and at the same place. So get the UUID of the Hard Drive using
sudo vi /etc/fstab and add a line at the end looking like thus:
UUID=5C24-1453 /mnt/PIHDD exfat defaults
man fstab for more info.
Sharing with your mac
On the Pi
- install netatalk:
sudo apt-get install netatalk
- edit the default configuration to allow the Pi user to access the /mnt/PIHDD we just created:
sudo nano /etc/netatalk/AppleVolumes.default``` At the end of the file, after or instead of Home Dir, add /mnt/PIHDD and name it, e.g. MyMedia, then restart netatalk: ```sudo /etc/init.d/netatalk restart```
On the Mac:
- Finder > Go > Connect to server >
- make the mount sticky on the Mac side in System Preferences > User account > adding the volume to the login items.
