cannot defrag volume, fragmentation factor 21.73%

[Richard Ems]

Hi all,

this is on openSUSE 11.3.

# uname -a
Linux fs1 2.6.34.7-0.3-default #1 SMP 2010-09-20 15:27:38 +0200 x86_64 
x86_64 x86_64 GNU/Linux

# echo frag | xfs_db -r /dev/disk/by-label/data1
xfs_db> actual 6451844, ideal 5050129, fragmentation factor 21.73%

# xfs_db -V
xfs_db version 3.1.2

# xfs_fsr -V
xfs_fsr version 3.1.2

# df -h /dev/sdb1
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdb1              17T   13T  4.3T  75% /data_1


The volume is new, 12TB were rsync'ed from another volume, some new 
files came after the sync.

I ran several times xfs_fsr, but the 21.73% factor stays there.
There where some busy or modified files on which I started xfs_fsr later 
again, but this ones where small files and the 21.73% is still there.

Any ideas?

Richard
