Some of the physical volumes show "Allocatable yes (but
full)" while others don't. How does one relate this to the actual
capacity? THe reason I am confused is that 3 of my PV's show up as
full and each is 1.63 TB. Thus the total full space would come to 4.89
TB. But the sum of full space of all my LV's is only around 3 TB
(based on the output of df)
I've reproduced the outputs of pvdisplay, lvdisplay and df below.
I'm confused! Any pointers?
