See my reply to cwillu for the data.
Can you try with the compression option enabled? Eg: # filefrag foo.dat foo.dat: 11 extents found # find . -xdev -type f -print0 | xargs -0 btrfs filesystem defragment -c # filefrag foo.dat foo.dat: 1 extent found Seems to work fine on 2.6.39-rc5; I mounted with '-o compress,clear_cache' though.
