Hi,

--- Quote Start ---

But I actually want to know that ,

when I create a volume by 55 MiB size and I get it as 49 MiB size after df -h, then

for what purpose 6 MiB (55MiB - 49MiB) is used ?

Why I could not able to see 55 MiB size, as allocated total space. ?

I think that the reason is written here.
