Understanding sfdisk and df results
Hi,

Using fdisk I created a partition of 15.7 GB. I entered +15700M

Using sfdisk there is a heading called blocks and there is a number which is approximatly 400 BM less. When I mount the partition and use df -l the 1K block column displays only 15GB!

I need to understand these numbers if I am going to create a partition of an appropriate size. Can anyone tell me the mathematics behind these numbers please!

Preliminarily I am thinking it has to do with "rounding off" of file sizes according to different schemes:

take a look at the fstab man page as it has options for

fstab -b = sectorsize of disk

fstab -C = cyls

fstab -H = heads

fstab -S = sectors per track of the disk (used for partition tables)

I think this is what you are asking.............?

the man page for df states that using the -l option gives results of the local filesystem only.

not sure what that means exactly right at the moment, but also you can use df -h

for "human readable" either in kb, MB, or GB

hope this helps.
