Basic installation

Installation is quite simple. Grab the current version of Raspbian-Jessie-Lite and install it to an micro SDHC card. Configure the system to taste.

Then attach an external usb-disk, and execute the following command:

sudo fdisk /dev/sda

If the disk is already partitioned, you should first delete all existing partitions. Use the p-command (print) to check for existing partitions and the d-command to delete them. Once the print-command does not show any partitions anymore, create a new one with n. You can accept all defaults, this will create a single partition which takes up all available space. Leave the fdisk-program with the w-command (write). This will erase all data already on the disk, so make sure you don't loose any important data.

Next, you should format the partition, create a mount-point and mount the partition:

sudo mkfs.ext4 /dev/sda1
sudo mkdir /data
sudo mount /dev/sda1 /data

All space is now available in the /data-directory. Since the mount is temporary, you should now open the file /etc/fstab with your favorite editor andd add the following line

/dev/sda2 /data ext4 user_xattr,noatime,acl 0 0

Reboot and check with the df-command that the external drive is mounted and the space is available.

If you are a Linux-user you can automate all the above steps. For details, see auto_install.md.

In case you just want to test the image-tank, you can also go standalone without an HDD/SDD. In this case, you should at least create the directory /data as described above.
