Mai provato, ma dalla man-page di tune2fs:
opzione -j
-j Add an ext3 journal to the filesystem. If the -J
option is not specified, the default journal parameters will be used to
create an appropriately sized journal (given the size of
the filesystem) stored within the filesystem. Note that you must be
using a kernel which has ext3 support in order to actually
make use of the journal.
If this option is used to create a journal on a mounted
filesystem, an immutable file, .journal, will be created in the top-
level directory of the filesystem, as it is the only safe
way to create the journal inode while the filesystem is mounted.
While the ext3 journal is visible, it is not safe to
delete it, or modify it while the filesystem is mounted; for this reason
the file is marked immutable. While checking unmounted
filesystems, e2fsck(8) will automatically move .journal files to the
invisible, reserved journal inode. For all filesystems
except for the root filesystem, this should happen automatically and
naturally during the next reboot cycle. Since the root
filesystem is mounted read-only, e2fsck(8) must be run from a rescue
floppy in order to effect this transition.
Quest'ultima sembra fare al caso tuo:
On some distributions, such as Debian, if an initial
ramdisk is used, the initrd scripts will automatically convert an ext2
root filesystem to ext3 if the /etc/fstab file specifies
the ext3 filesystem for the root filesystem in order to avoid
requiring the use of a rescue floppy to add an ext3
journal to the root filesystem.
Quindi, se ho capito bene, dovrebbe bastare la modifica da ext2 in ext3
nella fstab.
In ogni caso, prima sempre il backup ...
Facci sapere.
