Man page of mkfs.ext4 suggests using "-O ^feature" to disable an ext4 feature. This seems to work: $ dd if=/dev/zero of=test1 bs=4M count=20 [...] $ mkfs.ext4 -F test1 [...] $ file test1 test1: Linux rev 1.0 ext4 filesystem data, UUID=408f6da2-c4ef-4335-9574-985f3a349ed2 (extents) (huge files) $ mkfs -O ^extent -F test1 [...] $ file test1 test1: Linux rev 1.0 ext4 filesystem data, UUID=23c046d6-db7a-419d-a1d5-0cba3c5b52d0 (huge files) Hope this helps, Vlad _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
