df -h showing full filesystem
I have today again such a problem. I have tried to write on the affected
partition and there is no problem.
Again "df -h" is showing a full partition. The btrfs details aren't showing
this full state.
It seems that only df has a problem.
To solve the problem i have started a scrub and after the start the df is
showing the "right" state.
