Two things you have to remember when looking at file
sizes/file system sizes:
- Reserved space
- Inode size
When you create a file system, a small percentage of it
is reserved. You can see this in 'man mke2fs':
-m reserved-blocks-percentage
Specify the percentage of reserved blocks for the
super-user. This value defaults to 5%.
Inode size determines the amount of disk space a file
actually takes up on the disk. A small 1k file could be
taking up 4k of space on the disk if your file system
uses 4k inodes. When a program counts the size of all
the files, you'll get one number; but when you look at
the actual free space on the disk, you'll get a different
number. (Disk waste due to large inodes was even worse
in DOS, up until they introduced FAT32. It's still not
as good as Linux/ext2, but at least considerably better
than it was.)
I'm not sure how inodes and such work with journalling
file systems. If you're using one, this may not apply.
