Hi,
edit by k-plan:
This Tutorial is outdated!
You can now use DietPi-Drive Manager.
It’s more simple and do all the steps for you with more options.
System:
DietPi V117 | ODROID-C1+ (e.g. in my case a fresh installation)
Micro SD-Card: - Verbatim 8GB Class 10 Micro SDHC
USB Device: - SanDisk Ultra Fit 64GB USB 3.0 drive
Boot up time: - ca. 25 sec
Note:
- should work on Hardkernel ODROID devices like: C0, C1, C1+, C2 (tested) and XU4, XU3 (tested by user)
Why to use this “extended version”?
Because it’s possible to use more than only one drive attached to your device.
# Preparation
- Install some tools we’ll need later:
root@oDroid-C1-TEST:~# apt-get install rsync
- Insert USB drive and check to see if usb is recognized:
rroot@oDroid-C1-TEST:~# lsusb
Bus 001 Device 003: ID 0781:5583 SanDisk Corp.
Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
- Locate the USB device name ( /dev/sdx ):
root@oDroid-C1-TEST:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 57.9G 0 disk
└─sda1 8:1 1 57.9G 0 part
mmcblk0 179:0 0 7.4G 0 disk
├─mmcblk0p1 179:1 0 128.5M 0 part /boot
└─mmcblk0p2 179:2 0 7.3G 0 part /
In this example, USB device is on sda. From this point on we use /dev/sda for the USB drive.

- Formatting the USB drive:
root@oDroid-C1-TEST:~# /DietPi/dietpi/dietpi-external_drive_setup
--------------------------------
D I E T - P I

root@oDroid-C1-TEST:~# dietpi-config

# Preparing to change root device (system)
- Now we need Partition unique UUID (UUID) of the USB device:
root@oDroid-C1-TEST:~# lsblk -f
NAME FSTYPE LABEL UUID MOUNTPOINT
sda
└─sda1 ext4 abe28749-d59f-415b-9b60-75b1007eeee9 /mnt/usb_1

└─mmcblk0p2 ext4 rootfs e139ce78-9841-40fe-8823-96a304a09859 /
e.g. Partition unique UUID: abe28749-d59f-415b-9b60-75b1007eeee9
- Backup your boot.ini file and edit it to include your new partition:
root@oDroid-C1-TEST:~# cp /DietPi/boot.ini /DietPi/boot.ini.sdcard
root@oDroid-C1-TEST:~# nano /DietPi/boot.ini
- Edit the file and change your root=UUID=… to point to new filesystem partition with the find out Partition unique UUID (UUID)

- Copy the filesystem over to your new partition:
root@oDroid-C1-TEST:~# rsync -axv / /mnt/usb_1/
...
sent 485,999,479 bytes received 431,075 bytes 7,314,745.17 bytes/sec
total size is 484,388,706 speedup is 1.00
Be patient - this will take some time!
- Get your partition UUID for fstab:
root@oDroid-C1-TEST:~# lsblk -f
NAME FSTYPE LABEL UUID MOUNTPOINT
sda
└─sda1 ext4 abe28749-d59f-415b-9b60-75b1007eeee9 /mnt/usb_1
...
e.g. UUID=abe28749-d59f-415b-9b60-75b1007eeee9
- Backup and edit the fstab file on your new filesystem:
root@oDroid-C1-TEST:~# cp /mnt/usb_1/etc/fstab /mnt/usb_1/etc/fstab.sdcard
root@oDroid-C1-TEST:~# nano /mnt/usb_1/etc/fstab
- Comment out the old filesystem at /dev/mmcblk0p2 and add the new line pointing to your new filesystem and add your UUID as indicated.

and save the file!
root@oDroid-C1-TEST:~# umount /dev/sda1
- Cross the fingers and reboot your ODROID:
root@oDroid-C1-TEST:~# reboot
If your USB device have a activity LED, you can check here R/W activity.
Boot up time is now: ca. 20 sec
- After your device has booted up, check the filesystem information:
root@oDroid-C1-TEST:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 57G 581M 54G 2% /
udev 10M 0 10M 0% /dev
tmpfs 190M 5.4M 185M 3% /run
tmpfs 475M 0 475M 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 475M 0 475M 0% /sys/fs/cgroup
tmpfs 10M 1.1M 9.0M 11% /DietPi
tmpfs 20M 12K 20M 1% /var/log
tmpfs 475M 0 475M 0% /tmp
/dev/mmcblk0p1 129M 25M 104M 20% /boot
- Create a new swap file (e.g. 101 MB):
root@oDroid-C1-TEST:~# dietpi-config
dietpi-config => 4 Advanced Options => 1 Swapfile Size
- Now benchmark filesystem and RAM IO performance again:
… and reboot.
Note:
- To boot your device, you must have insert SD-Card any time. Without it will not boot.
- If somethings goes wrong or your device doesn’t boot, power off your device, put SD-Card into your PC and restore "boot.ini.sdcard " to "boot.ini " on the DOS (FAT) partition named "boot "
Put edited SD-Card back into your device and power on. It will boot and run the system (DietPi) now from SD-Card like before your modifications.
