Package: e2fsprogs
Version: 1.41.3-1
Severity: normal
It seems like the filefrag doesn't report the correct results for files
without any allocted blocks:
mkfs.xfs /dev/vdb5
mount /dev/vdb5 /mnt/scratch
touch /mnt/scratch/foo
filefrag /mnt/scratch/foo
/mnt/scratch/foo: 1 extent found
While xfs_bmap gets the right results:
qemu1:~/xfstests-dev# xfs_bmap /mnt/scratch/foo
/mnt/scratch/foo: no extents
When actually having extents it seems fine:
qemu1:~/xfstests-dev# echo "foo" > /mnt/scratch/foo
qemu1:~/xfstests-dev# filefrag /mnt/scratch/foo
/mnt/scratch/foo: 1 extent found
qemu1:~/xfstests-dev# xfs_bmap /mnt/scratch/foo
/mnt/scratch/foo:
0: [0..7]: 96..103
The behaviour is similar on ext3, but no tool to verify it there:
qemu1:~/xfstests-dev# mkfs.ext3 /dev/vdb5
mount /dev/vdb5 /mnt/scratch/
qemu1:~/xfstests-dev# touch /mnt/scratch/foo
qemu1:~/xfstests-dev# filefrag /mnt/scratch/foo
/mnt/scratch/foo: 1 extent found
