How to convert a ext3 filesystems in to an ext2 filesystem in linux?

petulia3478

To convert from a ext3 (journalling filesystem) to an ext2 (no journalling filesystem) run the following commads:

Unmount the filesystem first

# umount /test

Run tune2fs to remove the journal option

# tune2fs -O ^has_journal /dev/mapper/vg01-test
tune2fs 1.35 (28-Feb-2004)

Perform a filesystem check

# e2fsck -y /dev/mapper/vg01-test
e2fsck 1.35 (28-Feb-2004)
/dev/mapper/vg01-test: clean, 12/2048 files, 1335/8192 blocks

Mount the filesystem

# mount -t ext2 /dev/mapper/vg01-test /test

Remove the .journal file

# cd /test
# rm -f .journal
