How to get rid of Online (VPN only) mode in a beaglebone-black device

agaurav · November 20, 2020, 2:49am

Hi, I have a couple of questions/doubts.
1.) After getting “No Space Left On Device” message in the log window, my device has gone into Online (VPN only) mode and I am not able to restart/reboot it any more.
It gives the below error.

How can I go back to normal without re-flashing the device?

2.) I also see that the storage if full but I am not sure what caused this and I am somewhat certain it was not my applications. I am also not able to see the logs anymore because I am not able to ssh inside the container.

What could have caused the memory to be full?

Is the docker diffs in /var/lib/docker/?

If Yes, Can I clean some of these?

Can someone please give me insight of what is going on.

Thanks

Hi there, if you are able to connect to this device still with a terminal, running df -h would be the first thing I would run to see where the disk space has been consumed. If you grant support access to the device and share the uuid, we could also take a look for you.

@ab77
Hi, The device came back to normal itself after sometime. I am keeping an eye on it. I will let you know if it happens again.
Thanks

Hi

It would be nice if you can also enable persistent logging on the device. This will help debug this issue faster if it happens again.

Hi,

I encounter the same issue but on Jetson Nano devices. Persistent logging is enabled. I see following messages in journaling:

Jan 12 14:40:51 37b512f systemd[1]: This usually indicates unclean termination of a previous run, or service implementation deficiencies.

Hi.

Did you also get the No space left on your device on these devices? What is the output of the df -h command? Could you also provide the output of running the following command on your devices?

journalctl -u resin-supervisor --no-pager

If you can run ‘Device Diagnostics’ and share the output with us, that would also be very helpful. Thank you!

I didn’t saw the “No space left …” message but I know the devices are full. When I check using df and du, I see almost all data is consumed by /mnt/data/docker/overlay2.

The output of the command journalctl -u resin-supervisor --no-pager (most important part):

Hi again, if the drives are full, that would explain the Cannot connect to the balenaEngine daemon at unix:///var/run/balena-engine.sock. You could try getting the engine log using journalctl -u balena --no-pager -n 500 to see if there is any relevant information there.

Otherwise to clean up the data dir, you could first see if you can get the engine up with systemctl restart balena and check for status systemctl status balena. If that works, you can try doing a balena system prune as well as deleting any unused images you see listed with balena images.

If restarting the engine fails, you can try cleaning up the /var/lib/docker directory, but this will delete all your application images and data. If you are ok with that, you can do the following to perform a cleanup

systemctl stop resin-supervisor
systemctl stop balena
rm -rf /var/lib/docker/{aufs,overlay,containers,image,tmp}
systemctl start balena
systemctl start resin-supervisor

Do you have any clues about why your data partition might be full, what is the size of your drive? What is the size of the application images?

I resolved the issue once removing the biggest folder in /mnt/data/docker/overlay2. And then do balena system prune which removes the dangling data.

I have no idea why the data partition went full, I can say the size of images/containers is approximately 60% of the full storage size.

Great to hear that you were able to resolve the issue after removing some stuff.

Can you share the size of your images?
Did you happen to see if there were a lot of errors (failed timeouts, etc) when updating your images?

Clint · January 13, 2021, 3:49pm

I solved the issue on a device once, but now I still have 2 devices running with the issue.

Maybe a good idea to give you guys access to the devices?

ab77 · January 13, 2021, 9:34pm

Hi there, well you do have one 5GB+ image there, so this one is most likely going to take some time to download/calculate deltas between releases and/or eat up disk space if there isn’t a lot to begin with. How much disk space do you have available on this device (/mnt/data)?

ab77 · January 14, 2021, 12:29am

You may also benefit from reviewing your build as a ~ 6GB docker image in IoT space is unusual. Perhaps this build can be optimised to use multi-stage builds, not to persist all of the build dependencies in the final runtime?

Clint · January 14, 2021, 10:48am

The mount /mnt/data is 14GB.
We have different layers and Dockerfiles in the images/containers, but it looks like when a Balena service is defined one final runtime is created.
The image is so big because of all the NVIDIA stuff. It’s a NVIDIA Jetson Nano device

rahul-thakoor · January 15, 2021, 10:59am

Hey there! I’m not sure I follow what you mean by

but it looks like when a Balena service is defined one final runtime is created.

Can you please clarify? or better, can you please share your Dockerfile?
