Converting from Ext3 to Ext2

There may come a time when you want to convert EXT3 to Ext2. For directories other than the root directory or /usr, it’s pretty easy. The following uses the example of /dev/hda10 mounted to directory /test:

* umount /dev/hda10

* tune2fs -O ^has_journal /dev/hda10

* e2fsck /dev/hda10

* Edit /etc/fstab to change /dev/hda10 to mount type ext2

* mount /dev/hda10

The tune2fs command removes the journal inode, and the e2fsck command completes that removal.
