There are no very big files, surely some with a couple of GBs but not
more. All files are defragmented.

Attached the gzipped output of 3 runs of xfs_fsr generated with the command:

{ set -x ; for i in 1 2 3 ; do date ; echo frag | xfs_db -r
/dev/disk/by-label/data1 ; date ; xfs_fsr -v /data_1/ ; date ; echo frag
| xfs_db -r /dev/disk/by-label/data1 ; date ; done ; set +x ;} >
~/logs/defrag/data1/xfs_fsr-HOME-2010.10.18-1.log 2>&1 &

Thanks, Richard
