Migration to Balena

Product support
1

Hey all,

We’ve been testing out Balena and it seems like it is the solution to our problems. Before we go full steam ahead we wanted to see how we can migrate our devices remotely as we have several hundred devices out in the wild.

Our devices are composed of BeagleBone Black components with Debian 9/10.

I found the takeover script, however there is an unmerged PR from 2022 that says that takeover is under limited maintenace as the will be a new method. You can find more about here.. In addition, I have also found several forum posts that support this.

Using the takeover script, the debug logs seem fine however after it reboots, nothing has changed. I connected via serial to see if there is something happening during boot, however there were no clues there either.

The output can be found at the bottom of this post. However I would like to know what the up to date method is to do a brownfield migration.

sudo ./takeover --log-level debug --image beaglebone-black-5.3.4+rev3-v16.1.10.img.gz --no-wifis --no-nwmgr-check -c config.json

Hello @aslansutu let me ask to the OS team how to help you more with the takeover script or further initiatives we are working on.

In the meantime, if you do any other successful (or not) test, let us know!

3

Hey @aslansutu is it possible that you could share the logs of the stage2?

Read more about the stage 2 here in the README

Feel free to share the next steps!

Thanks, Marc. Also see the Logging section of the README to specify stage2 logging. Let us know how it goes.

If I understand correctly, the RAMFS is /tmp/balena-takeover, or am I mistaken?

Hello @aslansutu the takeover script needs to copy the required files (including the balenaOS image) to the RAM memory, because storage (disk, SD, etc.) will be fully overwritten when the device is reflashed.

What is surprising is that the logs say Found 484 MiB total, 253 MiB free memory. It’s odd to see the device with only 253MB of RAM free even after we killed all the other running processes.

Could you please share more details of the model and the application that you are running currently? Our team is researching to enable you with the takeover script!

Thanks

Absolutely.

The device is a Beagle Bone Black Rev. C. We are currently using the Debian image provided by BeagleBoard. Some are Debian 9.3, some are be Debian 8. The one I was trying with was Debian 9.3.

There are no complex changes to the system. It has a simple frontend and backend (Python) and communicates with other external components via its pins.

I will go ahead and try with a fresh Debian image in the meantime to check if it has something to do with any changes we made. Also thanks in advance for the help.

@aslansutu very soon one of my colleagues is going to test in one of his Beagle Bone Black and we will let you know more!

Please do test on another Beagle Bone with a different Debian version and feel free to share the logs here!

Thanks!

Thanks for reporting the failure with takeover @aslansutu. I was able to migrate a Beaglebone Black running Debian 9.5 using the 5.3.4+rev3 image. Let’s see if my experience helps your effort.

I see you specified the image as beaglebone-black-5.3.4+rev3-v16.1.10.img.gz Are you sure this image is a raw image and not a flasher image? The download from balenaCloud provides a flasher image. You need to extract the raw image from it. The raw image is stored in the /opt directory of the flash-rootA partition. See the balena-image-flasher-unwrap repo for a straightforward way to extract the raw image.

On my device, Apache2 was running. The takeover script apparently was unable to dispose of some process related to it. Once I manually stopped Apache before running takeover, the device migrated as expected.

I have attached the logs from my success run. Let us know how it goes.

stage1.log (53.3 KB)
stage2-init.log (3.4 KB)
stage2.log (26.0 KB)

So I finally got a chance to retry. I had initially tried downloading the image and passing it over to the script because without it, I would get the error that can be found in stage1-failed.log

I dunno why, but after trying again it seemed to work better. This time the issue seems to stem from the fact that it is unable to remount because the file system is readonly. The device I was using had a fresh Debian image flashed that can be found here (bone-debian-9.3-iot-armhf-2018-03-05-4gb.img.xz). I am going to try a couple more things to see if I can get it to work.

However the original issue was about not enough memory, that could mean I will have to manually kill some of the processes that we have started. I just wanted to update my journey in case anyone else also gets stuck. I have also went ahead and attached my logs as well.

stage1-failed.log (8.1 KB)
stage1.log (17.3 KB)
stage2-init.log (816 Bytes)
stage2.log (28.4 KB)

I experienced the same divide by zero with the image download as you report in stage1-failed.log. That was fixed with PR #82.

Your stage1.log got past that point, but it reported a 404 failure on the download and only downloaded 37 bytes. Been there, done that. :slight_smile: See Issue #83. That one has not been fixed yet.

Your stage2.log fails with an inability to unmount a partition. I see traces of Apache2 logs, so I expect this problem is the same as I encountered. See Issue #84.

Suggestions:

I don’t see evidence that you have the required balenaOS image because the download within the takeover script failed. Be sure to verify from my last message on how to collect the raw image. The gzipped raw image is around 185 MB, while the gzipped flasher image is around 290 MB.

Once you are sure you have the right image, follow #84 to stop the Apache2 process, and give it another try. I expect from start to finish takeover will require 5 or 10 minutes to complete. Once the stage1 log display finishes, eventually you should see the blink patterns on the BBB stop as it reboots, then the next indication is the device showing on the balenaCloud dashboard in the fleet you defined in config.json.

You’re making progress. Thanks for your patience as we get this working.

After finally finding time to work on this again I was able to migrate it following @kb2ma’s steps. Just so if anyone else get stuck, I want to document what I did.

Takeover Script

The take over script can be found here in its repo. No need to clone the repo, just download the relevant release. For the BeagleBone Black, it was takeover-armv7-unknown-linux-musleabihf.tar.gz . Extract and you should have the takeover script.

Config

Using the Balena dashboard, once you create a fleet, you can add a device. On the bottom right hand corner, you can choose to only download the config file.

Image

Using the dashboard again, instead of choosing to download the config I downloaded the balena-os image. I believe you can also use the images found in Balena’s website.

You will also need to clone the Balena Image Flasher Unwrap.

The Balena image you have downloaded should have the extension .img.gz so go ahead and unzip that. Copy the .img file to the Balena Image Flasher Unwrap folder. In that folder you can find instructions on how to use it. But essentially it is
./docker-run /absolute/path/to/balena-os.img
Once executed, you can find the file in the output folder. Navigate to the output folder and you will see an img file. We need to now gz zip that. gzip balena-os.img which should output a file with the extension .img.gz.

Execution

Copy the config.json, takeover, and (newly zipped) balena-os.img.gz files to your device.

In order to not leave everything to the script, I wrote a small script that should kill all non essential process. Here is the script if anyone wants to use it.

#!/bin/bash

# Get the process IDs of essential services
ESSENTIAL_PIDS=$(pgrep -f 'sshd|bash|sh')

# Print all processes except the essential ones
ps aux | grep -v -E 'sshd|bash|sh' | awk '{print $2}' | while read pid; do
  if [[ ! "$ESSENTIAL_PIDS" =~ "$pid" ]]; then
    echo "Killing process ID $pid"
    kill -9 $pid
  fi
done

Afterwards I just ran the following commands;
sudo su -
./takeover -c config.json -i balena-cloud-auto-flow-beaglebone-black-5.3.4+rev3-v16.1.10.img.gz --no-nwmgr-check --no-wifis --log-file /root/migrate/stage1.log --log-level trace -l /dev/sdb1 --s2-log-level trace

Obviously, make sure that the paths are correct. (I dunno if having the files in /root and running from there has an effect). The first time I ran it, I ran into some issues. Turns out I had tar.gz zipped my image instead of just gz. The second time I was told that there is not enough memory. However third time worked like a charm.

The only thing I do not know is where to get the config file if one is using openBalena instead of the dashboard. But I guess that problem is for another day. To anyone needing help with this, let me know if anything I’ve said is vauge, I can try to elaborate more.
