Does it really this command? I consider it will fill up
whole /dev/vdb. And is it not subvolume/bigfile.img
but bigfile.img?

If bigfile.img is just under /mnt/test, I can't understand
why this command succeeded to write more 3 GiB.

It normally would fill the fs if left for long, but I've pressed ctrl+c
after about 6 GB.

If I recall correctly, it was not inside the subvolume.

The previous command wrote 6 GB, this one wrote 3.1 GB - there was still
plenty of free space.
