So in summary, currently on (2.6.39-rc3), the following will (usually?) report a single unwritten extent, on both ext4 and xfs fallocate -l 10MiB -n k dd count=10 if=/dev/urandom conv=notrunc iflag=fullblock of=k filefrag -v k # grep for an extent without unwritten || fail This particular issue has been discussed so far at: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8411 Note there it was stated there that ext4 had this fixed as of 2.6.39-rc1, so maybe there is something lurking? cheers, Pádraig. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
