I'm not sure that you can, unless you remove the file, unmount the filesystem, and then add the journal again. Something like (assuming /dev/blah is mounted at /blah): % # make backups!! % chattr -i /blah/.journal % rm /blah/.journal % umount /dev/blah % tune2fs ^has_journal /dev/blah % e2fsck /dev/blah # if tune2fs asks for it % tune2fs -j /dev/blah % e2fsck /dev/blah # if tune2fs asks for it % mount /dev/blah Andrew.
