Convert ext2 to ext3
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):
# tune2fs -j partition
Where partition is /dev/sda1, /dev/hda1, /dev/discs/disc0/part1, etc.
3. Edit /etc/fstab and change ext2 to ext3 for the partition.
For example:
/dev/sda3 / ext2 defaults 0 1
becomes:
/dev/sda3 / ext3 defaults 0 1
4. Add the ext3 module to /etc/mkinitcpio.conf:
MODULES="ext3"
5. Rebuild the initrd image (for a standard kernel):
# mkinitcpio -p linux
