I have to identical partitions I formatted with the same tool.
I copied everything from one partition to the other still
the file system usage is different. Why?
.
rsync -a /mnt1/ /mnt2
.
Interestingly the file systems usage is not the same for
the two partitions (part7 is mnt1, part8 is mnt2):
.
df -h
Filesystem Size Used Avail Use% Mounted on
.
/dev/sdc7 28G 6.1G 21G 24% /mnt1
/dev/sdc8 28G 6.7G 20G 26% /mnt2
.
Why is this difference?

man rsync tells you:
-a, --archive archive mode; equals -rlptgoD (no -H,-A,-X)
...
-H, --hard-links preserve hard links

My reading is unless you preserve hard links, you get at least two separate
files on the target for each hard linked file on the source. So if you really
want a clone, either clone, or use rsync -aHAX.

I will try this if it makes any difference.

Thanks,

Istvan
