AGL storage issue

[m-lenz]

When working with AGL the whole OS takes up ~5GB of the SD-cards 16GB

raspberrypi3:~# du -hs / 
=> 2.4G	/

raspberrypi3:~# df -h /
=> Filesystem      Size  Used Avail Use% Mounted on
=> /dev/root       2.5G  2.3G  1.4M 100% /

raspberrypi3:/usr/bin/kuksa-hawkbit# du -hs /tmp/        
=> 152K	/tmp/

raspberrypi3:/usr/bin/kuksa-hawkbit# df -h /tmp/         
=> Filesystem      Size  Used Avail Use% Mounted on
=> tmpfs           438M  152K  438M   1% /tmp

Even though there is enough space inside the /tmp/-directory, the app-manager` is unable to download apps:

[Errno 28] No space left on device

I tried it with small (33MB), medium (70MB) and large(350MB) apps and non of them can be loaded.

When using the foreverChecker and Hawkbit however, there is no issue downloading multiple images and saving them inside the /tmp/ directory.

Until this is fixed we won't be able to test the app-manager any further.

@rai20 What is different in our setup of appmanager on the dongle? We are using appmanager, and downloading also the fat 80MiB traccar docker without problem. And the emmc variant has only 4 GiB... Can you show df -hand mountof our setup and clarify where we are downloading to?

[m-lenz]

df -h shows empty space in /tmp (Apps are downloaded to the /tmp-directory):

at the moment /tmp yields ~500mb of free space, but the appmanager will need 350 of those and won't allow further downloads. When the SD-card is mounted ion another it shows 16GB in size, while df and du suggest a maximum usage of 6-7GB.

and this is the output of mount:

Since everyone in the call hadn't had this issue, please tell me how you deviated from the original build-instructions to achieve this.

I don't think this is an issue with the way you build the Image. So here are the steps I follow to flash the SD card.

1. Use gparted to delete the existing partition (if any) on the SD card.
2. Create a new partition occupying all the available memory on the card and format it as ext4.
3. Now use Etcher to flash the card.

Another question would be, how have you deployed the appmanager? native or as docker container?

I use the appmanager in a docker container and have faced no space related issues.
I have not tested the native deployment.

@rai20 Since this issue is still a thing, so we deploy the app-manager using docker.
Edit2: I heard the new AGL ships with the app-manager inside the kuksa-layers, but we have no way of testing it for now.

Edit: Apparently the SD card was flashed on a Macintosh so we gonna look into that as soon, as the new image is done building. I will close this issue, until these things happen again on the new image
