Having Fun While Converting ext2 to ext3 and Vice Versa

23.07.2005 at 12:50

Ok this time I was playing around with different filesystem types. I found this page quite useful by doing so, here is a short summary of the most important commands:

# make a normal ext2 filesystem
mke2fs /dev/hda1
# add a journal and therefore make it to an ext3 fs
tune2fs -j /dev/hda1
# ok now lets remove the journal
tune2fs -O ^has_journal /dev/hda1
# check if still everything is ok
e2fsck -f /dev/hda1

Maybe I should have read the documentation before starting to code.
