Hi, This is working as expected. As files are not split up (unless you are using shards) the size of the file is restricted by the size of the individual bricks. > > This resulted in the absurd situation that the user could see a filesystem > with massive amount of free space, but still got a filesystem full error. > > This is misleading, yes.
