[linux-lvm] show free space _inside_ logical volume

[Mark H. Wood]

Well, the LVM tools will tell you the size of the LV, and filesystem
tools will tell you the size of the filesystem.  You have to do the
subtraction yourself.

Depending on what's most important to you, to have either set of tools
work with the other's data would either be a layering violation, cause
unnecessary and fragile coupling of unrelated tools, or make them
needlessly complex.  Both toolsets need to remain small, light,
rugged, and simple, because they're used for standing up and repairing
systems that may not be ready for daily use.
