---------------------------------
Sorry the alignment I posted here is a mess. It's not related to the patch.
> Minimally replicated blocks counting from fsck is misleading

> "Minimally replicated blocks" actually means "*at least* Minimally replicated
> blocks" here.
> I want to know how many blocks are in danger, whose number of replicas is
