Ah, sorry, I'm too focused on the problem that Anand's script pointed out.

As you said, running balance & cp lead to such messages, so I think there are some unintentional redundency works over the mounted devices when dealing with umounted ones. I'll try to o stalling: This may be due to concurrency problem either. After the first problem handled, let's see what happens.
