Installing artifact - Unexpected EOF

[Sebastian Bauhaus]

Hello!

I am new to Mender and currently trying to deploy artifacts to a Raspberry Pi 3 device.

The full size of storage is set to approx. 25 GB resulting in 12 GB per partition.

The compressed artifact size is 50 MB. When I try to deploy the update, I can see that the activity-LED on the raspberry pi is lid for about 3h. The syslog of the raspberry:

I cannot tell if this update is going to end after a few more hours - is this normal behaviour? Do I need to decrease the size of space in the partition? 

Thank you

Sebastian

1. You don't need to have 12GB partitions if your artifact is just 50MB. You should make A/B partition say 2GB (in case if your artifact will grow that far) and the rest used as data partition. A/B partitions should be read only and so making them extremely big is just waste of space.

2. Looking at your log I can say that it progresses forward and eventually likely to complete. If it will fail you will see it in Mender UI. Mender updates over slow/bad connections are not super fast but they are like a freight train: once they on the go they will likely arrive.

Wriing 12GB might be slow on a raspberry, depending on the sd card used..

Also take a look at this as well. https://tracker.mender.io/browse/MEN-1511

Which client version are you using?

Thank you. This is indeed much better. I moved the application data to /data and resized the partitions. Deployment is working now! :-)
