If you have installed Arch to an ext2 filesystem, it is a good idea to enable the journal and turn it into an ext3 filesystem. Journaling provides a range of benefits.

1. Identify the partition(s) for conversion by inspecting /etc/fstab and the output of the mount command

2. Add a journal to the partition(s):

sudo tune2fs -j PARTITION

Where PARTITION is /dev/hda1, /dev/sda1, /dev/discs/disc0/part1, etc.

2. Edit /etc/fstab and change ext2 to ext3 for the partition.

For example:

/dev/sda3 / ext2 defaults 0 1


/dev/sda3 / ext3 defaults 0 1

3. Add the ext3 module to /etc/mkinitcpio.conf


4. Rebuild the initrd image (for a standard kernel):

sudo mkinitcpio -p linux
