[opensuse] file system usage?
Hello:

Shortly:
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?

Longer version:

I have two extended partitions on the same hard disks.
They have identical sizes and block numbers.
fdisk report is:

Device Boot Start End Blocks Id System
/dev/sdc7 399155791 457744782 29294496 83 Linux
/dev/sdc8 457744846 516333837 29294496 83 Linux

I formatted both partitions as ext4 using Leap 42.2 yast2
partition tool with its default options. I installed Leap
42.2 onto partition 7. Partition 6 also has Leap 42.2 installed
earlier. I booted part6 Leap 42.2, mounted partitions 7 and 8
(as /mnt1 and /mnt2) and rsynced everything from partition 7 to 8:

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?

Thanks,

Istvan
