ODROID-XU4 with OpenMediaVault


Nearly 3 years ago I have bought myself a PogoplugV2 (see Post). It is still an awesome device for this price and worked without any issue the whole time.

However it is time for an upgrade.  USB 2.0 was a little bit too slow for me (~30MB/s). In addition I have a lot of external USB 3.0 HDDs and it is time to use their full potential. So there are 4 key points a device needs to become my next NAS (Network-attached storage) and home server system:

  1. reasonable fast ARM processor with at least 2 cores (I prefer ARM over x86 for this use case because of its low energy consumption)
  2. Gigabit ethernet
  3. at least 2 USB 3.0 ports because I want to attach 2 active 4-port USB hubs. Almost all USB hubs >4 ports are cascaded 4 port hubs. This is quite bad because it can cause a lot of compatibility and of course performance issues.
  4. all together <150€. I do not want to pay 300-400€ for a simple NAS with USB disks…


After a bit of research I have bought an ODROID-XU4.
Let’s look at the specs:

  • ODROID-XU4Samsung Exynos5422 Cortex™-A15 2Ghz and Cortex™-A7 Octa core CPUs
  • Mali-T628 MP6(OpenGL ES 3.0/2.0/1.1 and OpenCL 1.1 Full profile)
  • 2Gbyte LPDDR3 RAM PoP stacked
  • eMMC5.0 HS400 Flash Storage
  • 2 x USB 3.0 Host, 1 x USB 2.0 Host
  • Gigabit Ethernet port
  • HDMI 1.4a for display
  • Size : 82 x 58 x 22 mm
  • Price: ~80 € + PSU ~8 € + Case ~8€ = ~96 €

I do not need the GPU and display output but whatever… the price is quite good for this performance. It is less expensive in US than it is in germany. But that is always the case 😉

Additional equipment

I am using a microSD Card for OS because eMMC is quite expensive. Boot times and program loading times are not that important my use case.
With two additional 4 port active USB 3.0 hubs I have 8 USB 3.0 ports and 1 USB 2.0 port. At the moment 5 disks are connected with a total of 7.5 TB storage.
Connecting a 2 TB disk to each USB 3.0 port would be 16 TB storage which should be good enough for some time.

  • SanDisk Extreme 32GB microSDHC UHS-I  ~20 €microSD card
  • 2x EasyAcc® Superspeed USB 3.0 4 Port Bus-Powered and Self-Powered 2-in-1 Hub  2x ~11 €easyacc-superspeed-usb-3-0-4-port-bus-powered-and-self-powered-2-in-1-hub
  • Anker 20W Dual-Port USB Wall Charger to power USB Hubs  ~10 €Anker wall charger


OS Choices

The ODROID-XU4 SOC is the same as its predecessor ODROID-XU3. That is why they share a common kernel and os images are compatible.
Nevertheless Exynos5422 SOC is not fully integrated in mainline kernel yet. That is why you have to use a custom kernel from hardkernel. But that is not a big issue because there a quite a few OS choices with the custom kernel like Android (ofc pretty useless for NAS), Ubuntu 15.04, Arch Linux, Fedora, Kali Linux, …

Also I really like Arch Linux I have chosen a different path this time. There is OpenMediaVault (OMV) for some Odroids. I thought hey let’s give it a try the web interface looks quite nice.
After a few days I can say I really like it. The web interface is really good and looks modern.
OMV is running on Debian Wheezy 7.9.


Download OpenMediaVault Image from: http://sourceforge.net/projects/openmediavault/files/Odroid-XU3_XU4/

Extract the downloaded image

Search for the path of your microSD Card with lsblk  or sudo fdisk -l

Write the image to your microSD card with the following commands:

Insert your microSD card and power your Odroid.
Then you can login via SSH or web interface:

username: root
password: odroid

Web interface
username: admin
password: openmediavault

I will not go into detail on how to configure stuff in the web interface because that is really easy and straightforward. I will focus on optimizing performance and adding a few neat features.

Basic configuration

Connect to your Odroid via SSH with default login credentials (see above).

Afterwards change your root password with passwd

You should change your web interface password, too.

Colorful Shell

Because we will use the shell for quite some time let’s add some color to it:

vi ~/.bashrc and comment out the following lines:

vi /etc/vim/vimrc and comment out the following line:

and some more set’s from the bottom of the file as you like.

Note: If you are not familiar with vi/vim  you can use  nano  to edit all files.

Performance tuning

Performance with default settings was really bad. Disk read and write was around 30MB/s to ext4 and SSH was laggy. After a few minutes I have found the issue. Per default OMV sets the conservative governor. This may work well with x86 CPUs or other ARM CPUs but with Odroid it is a pain.

In the web interface under “Power Management” is an option called “Monitoring – Specifies whether to monitor the system status and select the most appropriate CPU level.” This sounds quite good, problem is this option sets the cpu governor to conservative. Conservative governor with default settings works really bad on Odroid in combination with I/O.
Disabling this option sets governor to performance. All 8 cores at max clock speed the whole time produce quite a bit of heat (fan spinning a lot) and it is not really energy efficient.

CPU governor

But no problem we can change the governor to ondemand and with a little bit tuning your Odroid will fly. The following settings will replace conservative with ondemand governor if you enable the Power Management option.

vi /etc/default/openmediavault and append the following lines to this file:

Then regenerate the config with

Note: There seems to be a bug in OpenMediaVault. After disabling Power Management and enabling it again it does not change cpu governor anymore. To fix this do the following:

Ondemand governor tuning

I did a few benchmarks and this showed I/O performance (my main focus) depends a lot on the cpu frequency. Therefore we further have to tune ondemand governor to get full I/O throughput. To do so do the following:

Copy the following to this file

Afterwards change to ondemand governor and activate these values with

I did benchmarks with all these settings and for me this is the sweet spot. Nearly same performance as performance governor but lower frequency and less power consumption when idle.

Some explanation of all 3 settings:

sampling_down_factor: this parameter controls the rate at which the kernel makes a decision on when to decrease the frequency while running at top speed. When set to 1 (the default) decisions to reevaluate load are made at the same interval regardless of current clock speed. But when set to greater than 1 (e.g. 100) it acts as a multiplier for the scheduling interval for reevaluating load when the CPU is at its top speed due to high load. This improves performance by reducing the overhead of load evaluation and helping the CPU stay at its top speed when truly busy, rather than shifting back and forth in speed. This tunable has no effect on behavior at lower speeds/lower CPU loads.

up_threshold: defines what the average CPU usage between the samplings of ‘sampling_rate’ needs to be for the kernel to make a decision on whether it should increase the frequency. For example when it is set to its default value of ’95’ it means that between the checking intervals the CPU needs to be on average more than 95% in use to then decide that the CPU frequency needs to be increased.

io_is_busy:  if 1 waiting for I/O will increase the calculated cpu usage. The governor will calculate iowait as busy and not idle time. Thus cpu will reach higher frequencies faster with I/O load.

NTFS mount options

Besides the ondemand governor we will add the big_writes mount option to all NTFS mounts. In addition we will add noatime.

big_writes: this option prevents fuse from splitting write buffers into 4K chunks, enabling big write buffers to be transferred from the application in a single step (up to some system limit, generally 128K bytes).

noatime this option disables inode access time updates which can speed up file operations and prevent sleeping (notebook) disks spinning up too often thus saving energy and disk lifetime.

vi /etc/default/openmediavault and append the following

Then you have to unmount, apply, mount, apply all your NTFS volumes in the web interface.

With default mount options you get around 16 MB/s write. With big_writes you get up to 62 MB/s write. See this comparison below:

NTFS diagram

This looks fairly fast but keep in mind NTFS is very cpu intensive on such a system. Therefore real network throughput via samba (which is cpu heavy as well) is way less compared to a native linux filesystem. I tested this disk with samba and measured only ~30MB/s read and write speeds. This is considerably less than a native linux filesystem (see Samba benchmarks).

If you want to get full performance you have to use a native linux filesystem like ext4 or xfs. You really should!

More Monitoring

I really like the monitoring setup of OMV with rrdtool. Nevertheless I miss 2 graphs which I am interested in. It would be nice to have CPU frequency and CPU temperature graphs, therefore I extended the existing monitoring plugin.

Monitoring cpu frequency is no big deal because there is a native collectd plugin for CPU frequency. For CPU temperature we have to write our own collectd plugin which looks like this:

In addition to the script above you have to create new collectd configs and additional tabs in the web interface. I have done all that and uploaded the full sourcecode (including the script above) to GitHub: https://github.com/Obihoernchen/openmediavault-monitoring-odroid-xu4

Install these CPU frequency and temperature monitoring plugins with the following commands:

The default diagrams are a little small for my taste, that is why I have increased the size a bit:

vi /etc/default/openmediavault and add the following to this file

Afterwards update OMV’s config files with

Afterwards you will have 2 new tabs which show graphs like these:



Finally reboot to see if everything is working as expected.


All benchmarks were done with performance governor to get consistent results.


I have several USB disks connected to my Odroid. Expect one disk all are 2.5″ USB 3.0 disks. All USB 3.0 disks are connected to two active USB 3.0 hubs. The USB 2.0 disk is connected to the USB 2.0 port.
In the following you can find hdparm read and dd read/write benchmarks for all connected disks. As you can see the performance is quite good and should be near the maximum the disks can handle.

dd benchmark


All network settings are default OMV/debian settings.

Receive: 832 Mbit/s = 104 MByte/s
Send: 896 Mbit/s = 112 MByte/s

I am satisfied with these results as it is close to the theoretical maximum of 1Gbit/s.


Disk and network speed looks fine. Because there are windows machines in my network I have to use samba to share files. As you can see samba speed is quite good and very stable.

If you have any additional questions feel free to ask 🙂
I will try to update this post regularly with new optimizations etc.

  1. Hi Obihörnchen,

    thank you for this great article!
    Unfortunately it does not work for me. Even though the individual
    benchmark values are similar to yours, the samba performance is very poor, around 10 MB/s.

    I am using gigabit Ethernet, a USB3 drive with ext4.

    Just summarizing my benchmark values:

    write: 44.7 MB/s
    read: 107 MB/s

    iperf: ~ 900 Mbits/sec both directions

    The CPU governor is set to ondemand (‘cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor’
    shows 8x ondemand) and i also applied the IRQ tuning.

    In addition to the poor samba performance I noticed that I get a similar low performance for
    copying data from the mmc to the drive and back.
    While copying (samba or local) I see a lot of io-wait for the cpu. This can also be seen in the iostat:

    $ iostat -x 3
    avg-cpu: %user %nice %system %iowait %steal %idle
    1.28 0.00 2.81 19.47 0.00 76.44

    Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util
    mmcblk0 0.00 2.67 38.00 0.67 9558.67 3.33 494.59 0.11 2.80 2.85 0.00 2.72 10.50
    sda 0.00 1.67 0.00 81.33 0.00 9601.33 236.10 142.83 1754.59 0.00 1754.59 12.30 100.00

    Where is the bottleneck?
    Any advice to solve this problem is welcome.


  2. Dear Obihoernchen,
    am having major issues with the harddisk not being mounted properly. mount – a doesn’t do the trick, neither a reboot.
    This can only get fixed (no idea why) by shutting down the odroid and then restarting it. And only, if while it is booting there are no PCs connected to the network who are trying to establish a link automatically.
    What I found is that this happens always when using the OMV front-end to shutdown the odroid and in abiut 70% of the cases when using the console via ssh to shutdown the box.

    Any idea what is going wrong?

    1. just an additional idea: it is a 1tb SATA. When “listening” during the boot it sounds as if the odroid is ready even before the disk has started spinning up.

        1. yes, I do have a dedicated power supply. dmesg is not showing anything wrong.
          Reboot (shutdown -r) never works, Shutdown – h with power cord off and on for a reboot does work after 3rd-4th attempt

  3. Great article, thanks!
    However, I’m having problems getting the big_writes option to work. I added the line as you suggested to /etc/default/openmediavault, but after mounting the NTFS partition the mount command always returns:
    /dev/sdb2 on /media/7A60CBAF60CB7085 type fuseblk (rw,noexec,noatime,user_id=0,group_id=0,allow_other,blksize=4096)

    This is what is in syslog:
    Feb 24 12:02:21 beaglebone ntfs-3g[8399]: Version 2014.2.15AR.2 integrated FUSE 28
    Feb 24 12:02:21 beaglebone ntfs-3g[8399]: Mounted /dev/sdb2 (Read-Write, label “Movies”, NTFS 3.1)
    Feb 24 12:02:21 beaglebone ntfs-3g[8399]: Cmdline options: rw,noexec,noatime,big_writes,nofail
    Feb 24 12:02:21 beaglebone ntfs-3g[8399]: Mount options: rw,noexec,nofail,allow_other,nonempty,noatime,fsname=/dev/sdb2,blkdev,blksize=4096
    Feb 24 12:02:21 beaglebone ntfs-3g[8399]: Ownership and permissions disabled, configuration type 7

    So it seems that the big_writes option is included by OMV, but is ignored when mounting?

    I’m running the latest OMV3 following your upgrade post.

    Any ideas on how I could get the big_writes to work?


  4. greetings Obihoernchen!

    can you guide me how to enable HDD Temperature Graph, just like you enabled CPU temp and freq graphs, if possible?
    and do review my earlier Comment regarding samba transfer rates 🙂

    thank you for work for odroid

  5. Really nice guide, I will most likely use it when my XU4 arrives. What type of HDD are you using: 2.5 or 3.5 inches? And what capacity? Are you using the more powerful power adapter, recommended for the CloudShell?

    1. Have a look at my benchmark snippet all HDDs are described there.
      All are 2,5″ 0,5 – 2TB each.
      And I’m using a USB power supply as described in the post as well 🙂

      1. Ok, thank you. I started browsing all your posts and I found the answer already 🙂 I will definitely get a powered USB 3.0 hub. I find it a lot easier to use a 2.5 inches HDD, even with a powered USB hub.

  6. Can’t quite figure out why my writes are still ~30MB.

    Bottom of my file looks like:

    # Ondemand Scheduler
    # Optimize NTFS Performance
    # RRDTool graph width and height

    I am admittedly new to linux but I thought I followed the guide pretty well. I am using a usb3 external drive and just got my odroid xu4 today. Any idea what it could be?

  7. Hi there. Thanks four your tutorial.

    Is there such one for an environment with Linux and Mac only?

    I am intersted in an Odroid-XU4, Ubuntu Core/DietPi combination.

    1. I don’t know whether there is a tutorial out there, but just use NFS instead of Samba and you are good to go 🙂
      But even with Linux + Mac you can use Samba as well.

  8. Excellent tutorial.

    I got a XU4 and planning to try OMV with it. I have been using a Pine64 as a NAS (samba share) but the speeds are very low (approx. 15mb/s write speed to the attached USB hard drive in my LAN).

    My question is how does this combo performs in terms of power consumption (idle/peak)? I’m considering attaching 2 x USB 3.0 4TB hard Drives in RAID mode.

    Many thanks.

    1. Hi,

      thank you.
      For me it consumes about 10W idle with 5 HDDs (idle as well) attached. The odroid itself consumes maybe 3W idle. Under load and with some spinning hard disks it goes up to about 20W.

      1. I decided to give this a go after all.
        All were set up OK apart from the fact that I can’t get my HD’s (both USB 3.0) to be recognised by the 2 x USB 3.0 ports. On the other hand, they are recognised no problem when plugged one by one to the USB 2.0 port of the XU4. Any idea why is this happening? Is there any missing driver or anything else I could amend?

        Many thanks

        1. Hi Markus.

          Please disregard my previous post as I figured out what the problem was. I had to clean the 2 x USB 3.0 ports with rubbing alcohol. Therefore, anyone with a similar problem should try to clean the ports which tend to collect dust particles over time. Now both ports can see my drives without a problem.

          However, real life tests do not show good speed results so far. I can move files from my host pc to the XU4 nas with 7-10mb/s (write) which is about 50% the speed of my other nas setup featuring a Pine64 board and a USB 2.0 drive.

          My drives are both formatted to NTFS and wouldn’t want to change the file system if possible. Of course, these speeds still have nothing to do with the speeds you presented above, even under the NTFS file system. Something like 60/30 mb/s would be perfectly fine for my needs.

          Is there a way to check whether the governor has changed to ”on demand” (I have followed all steps above one by one) or a safe way to determine if my system can achieve optimal read/write speeds?

          I also wonder if you updated from Stone burner to Erasmus version? Do I have to run omv updater or is this going to ruin my setup and will eventually have to re-flash?


          1. Hey,

            regarding OMV upgrade have a look at my newest post: https://obihoernchen.net/1451/upgrade-odroid-xu4-to-openmediavault-3/

            Do you use the big_writes mount option? Should look like this:

            ps -ef | grep ntfs
            root 851 1 0 Feb10 ? 00:00:24 /sbin/mount.ntfs /dev/sda1 /media/B4D48115D480DB4E -n -o rw,noexec,noatime,big_writes,nofail
            root 938 1 0 Feb10 ? 00:00:23 /sbin/mount.ntfs /dev/sdc1 /media/4A98777798775FFD -n -o rw,noexec,noatime,big_writes,nofail

            To check your governor run:

            cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

            Please run lsusb -t and post the output.

            Did you try to benchmark your drives with dd (like I did in my post)?

    1. Simply use the built-in OMV RAID menu entry (I didn’t test it myself but this should work). Or if your data doesn’t change often a simple rsync to a 2nd drive might be enough?

  9. Awesome tutorial! this actually encouraged me to get an XU4 a couple of weeks ago (had a C2 previously but accidentally shorted the GPIO pins while moving, so it was a bitter sweet upgrade)
    I followed your posts in threads to this blog (as I also have a ProBox 4 bay plugged in via USB 3.0). hitting approx 70ish MB/s pulling data from the odroid but maxes out ~ 11-15 MB/s writing to it.

    firstly through it may have been the network running at half duplex but ran iperf with -r for up/down streams:

    Server listening on TCP port 5001
    TCP window size: 85.3 KByte (default)
    [ 4] local port 5001 connected with port 31980
    [ ID] Interval Transfer Bandwidth
    [ 4] 0.0-10.0 sec 877 MBytes 735 Mbits/sec
    Client connecting to, TCP port 5001
    TCP window size: 68.1 KByte (default)
    [ 4] local port 41271 connected with port 5001
    [ 4] 0.0-10.0 sec 785 MBytes 658 Mbits/sec
    -not a network issue
    -As you’d know the ProBox has its own power supply, so its not a power issue

    You also wrote a separate article indicating the second USB3 port shares a IRQ with the ethernet port, but Im not sure which port is the first port

    Timing cached reads: 1990 MB in 2.00 seconds = 996.44 MB/sec
    Timing buffered disk reads: 128 MB in 1.66 seconds = 77.11 MB/sec

    Ive been researching during the holidays for 2 weeks straight trying all different things (thought it may have been the OMB build so I swapped to a jessie build and built OMV on it, same speeds)

    Close to going bald from pulling my hair out trying to figure out what is limiting my write speeds

    Absolutely any incite/advice/help you could provide in relation to this issue would be greatly appreciated!

  10. Awesome, about to buy an ODROID-XU4 for the exact same reason! Could certainly use USB3 & Gigabit Lan. Does the fan ever get loud for you at all?

  12. hi,
    i am not able to use cloudshell-lcd plugin with this OMV image!
    Did you get it working? any help appreciated

  13. Hi Obihörnchen,

    thank you for this great tutorial!
    Especially the monitoring of cpu freq. and temp. is very cool.
    I would like to enhance this with an additional graph for the fan speed (so I can check the impact of different fan speed strategies on cpu temperature and the time the fan is active).
    Can you give me a hint how to do this?


    1. Hey,

      first of all you have to check whether you can read the fan speed from /proc/… or /sys/… (I don’t know whether the kernel exports this).
      Then you can create a script like this one: https://github.com/Obihoernchen/openmediavault-monitoring-odroid-xu4/blob/master/usr/local/bin/cputemp
      Afterwards you have to create all the other files you can find in this repo (collect.d and .js file).

      Let me know if you can get the fan speed from somewhere.
      If yes I may add it myself because I think it’s a nice addition.

      1. you can find fan_speed (and many others) from


        it sure would be a nice addition to get fan_speed graph
        thank you for your awesome tutorial

  14. i found a guide for fan setting:
    you can set a rule for udev, by creating a file in /etc/udev/rules.d with the desired settings, I used 60-odroid_fan.rules as the name on my system. The following should work on either an XU3 or XU4 as it matches based on the driver name of odroid-fan rather than the kernel name which is different in the two versions:

    DRIVER==”odroid-fan”, ACTION==”add”, ATTR{fan_speeds}=”1 20 50 95″, ATTR{temp_levels}=”50 70 80″

    maybe it interest you

  15. Hey,
    thank you for you for your amazing work.

    one question:
    is it possible to install a desktop enviroment on top of this?
    after installing lxde the ip still pops up and nothing happens

      1. Thank you for your reply.

        do you maybe know where the script is running that shows the ip on the screen? i think that that script is blocking the bootup of the desktop enviroment

  16. Thank you for this awesome set of instructions. I set all the CPU governor settings; however, I am seeing very slow iperf tests in (-d) simultaneously bidirection. Send: 400+ Mbits/sec Receive: 70Mbits/sec. I suspected a duplex issue; however, it appears the duplex is correct. Any suggestions of where to look?

  17. thanks, problem disappeared with a refresh of OMV.. strange but good it’s sorted!

    thanks again for the help


  18. Hi, titles are fine and it does update automatically every 15 minutes. The only problem is that once I click refresh I get the “RPC service not found (name=Rrd)”

    Can you confirm everything works on your end with OMV 2.2.2?


  19. Hi On refresh of the graphs I get

    RPC service not found (name=Rrd)

    Error #2000:
    exception ‘OMVException’ with message ‘RPC service not found (name=Rrd)’ in /usr/share/php/openmediavault/rpc.inc:93
    Stack trace:
    #0 /usr/sbin/omv-engined(500): OMVRpc::exec(‘Rrd’, ‘generate’, NULL, Array, 1)
    #1 {main}

    Any idea?

    Thanks a lot, great post btw
