Or to configure an existing ext3 filesystem to support extents: # tune2fs -O extents /dev/hda1 .... To convert from ext2 (a very old filesystem :) ) to ext4, it's necessary to add more options. I'm not sure which one made the trick. tune2fs -O has_journal,dir_index,filetype,extent,flex_bg,sparse_super,large_file,huge_file,uninit_bg,dir_nlink,extra_isize Also, /etc/filesystems does not contain an entry for ext4. /etc/efs2prog.conf is ok. -- Berendsen
