Device runs out of space, files are zeroed on other devices

I have an interesting situation here. One of the devices in my setup appearantly (Arm Linux on Android) ran out of space while synching (ie getting files form another node). I did not know it. But I saw that some of the files on my other Linux devices were showing up as 0kb, but those files were some megabytes before. The files in question were sent to other devices including the Arm Linux ones. So this Linux x86_64 device was the source of these files. Some how some of them started showing up as zero. When I copied them to the Linux device they were at least 60 mb each.

Curious situation.

This deserves an issue on github:)
