Ext3 users - Sep 2001 - Removing ext3 to use GNU Parted

Hi. What are the right steps to convert a file system from
ext3 back to ext2 ? I need to use GNU Parted to resize my
root file system and Andrew Clausen said I have to convert it
to ext2, resize, and then convert back to ext3. My journal is
visible.

My initrd.img (from which I plan to use Parted) contains both
ext2 and ext3.

I compile ext2 as a module in my other boot images.

You can run the commands:

tune2fs -O ^has_journal <dev>	# Clear journal flag
e2fsck <dev>			# Make sure everything is OK
parted <disk>			# Resize partition/filesystem
tune2fs -j <dev>		# Make a new journal

I'm surprised, however, that parted can't work with ext3.  As long as
the filesystem has been cleanly unmounted, it shouldn't need any extra
code except to recognize the COMPAT_HAS_JOURNAL flag.

Cheers, Andreas
