Hi
Does anyone know how to move the filesystem to a USB Drive.
I'm working with ODroid-XU4 with Dietpi OS that is being display at http://odroid.com/dokuwiki/doku.php?id=en:odroid-xu4.
I saw couple of post here , one for raspberry pi, which does not work for Dietpi, I was not able to find /boot/cmdline.txt file. And another one that speed up USB device
I was able to do this on Raspberry Pi 2, but would like to try with Odroid-XU4 and USB SDD drive. I really want to speedup my read/write time.
Hope someone could help me with this task
Thanks
Jorge
[Tutorial - Outdated] Odroid: - Move the filesystem to a USB Drive
Re: Move the filesystem to a USB Drive
Hi Jorge,
do not own a Odroid-XU4, but make a guide for all DietPi supported ODROID device.
You can give it a try and let us know, if it will work for you.

OUTDATED: Move the filesystem to a USB Drive
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This Tutorial is outdated!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:
- Insert USB drive and check to see if usb is recognized:
- Locate the USB device name ( /dev/sdx ):
In this example, USB device is on sda. From this point on we use /dev/sda for the USB drive.
- Formatting the USB drive:
- Mounting USB device:
- Benchmark Filesystem and RAM IO performance
10 Tools => Benchmarks Filesystem and RAM benchmarks => Flash Storage, USB Drive, RAM => Benchmark IO performance.
# Preparing to change root device (system)
- Now we need Partition unique UUID (UUID) of the USB device:
e.g. Partition unique UUID: abe28749-d59f-415b-9b60-75b1007eeee9
- Backup your boot.ini file and edit it to include your new partition:
- Edit the file and change your root=UUID=... to point to new filesystem partition with the find out Partition unique UUID (UUID)
Watch for "rootdelay=10 " and save the file!
- - - - - - - -
* Examples for other ODROID devices:
* - - - C2 - - -
* - - - XU4 / XU3 (tested by user) - - -
As well watch for “ root=UUID= ... ” and " rootdelay=10 " !
- - - - - -
- Stop the services:
- Copy the filesystem over to your new partition:
Be patient - this will take some time!
- Get your partition UUID for fstab:
e.g. UUID=abe28749-d59f-415b-9b60-75b1007eeee9
- Backup and edit the fstab file on your new filesystem:
- Comment out the old filesystem at /dev/mmcblk0p2 and add the new line pointing to your new filesystem and add your UUID as indicated.
- Comment out External Drives at /dev/sda1 ___ /mnt/usb_1 :
and save the file!
- Unmount your USB device:
- Cross the fingers and reboot your ODROID:
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:
- Create a new swap file (e.g. 101 MB):
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.

Hey k-plan,
thx a lot for this great tutorial!
Worked like a charm!
This one should get a sticky in the board.
Thx again for your time, support and sharing your knowledge. :mrgreen:

Hi k-plan
I was able to do what I needed. Great tutorial and pictures. Easy to follow. I couldn't have ask for more. Thanks a lot. You can say that UX4 has been tested successfully.
Thanks once again

Re: Move the filesystem to a USB Drive
Great guide thanks - just got this going on an XU4.
Re: Move the filesystem to a USB Drive
I had moved my root to usb SSD before months on Odroid XU4. Today my SD died so it did not boot. How can I keep the installation on SSD and perform a new installation on a new SD?
Any idea? Please HELP!



Any idea? Please HELP!
Re: Move the filesystem to a USB Drive
First are you sure the SD card has died? Have you tried to read/copy it on a Windows machine?
I would backup the SSD just in case, flash a new SD card with dietpi and use the instructions earlier in this thread to rebuild your system as it was.
Refer specifically to the sections on UUID and editing the boot.ini file.
