Because ext3 is relatively new, some disk utilities do not yet
support it. For example, you may need to shrink a partition with
resize2fs, which does not yet support
ext3. In this situation, it may be necessary to temporarily revert
a file system to ext2.
To revert a partition, you must first unmount the partition by
logging in as root and typing,
umount /dev/mapper/VolGroup00-LogVol02
|
Next, change the file system type to ext2 by typing the
following command as root:
/sbin/tune2fs -O ^has_journal /dev/mapper/VolGroup00-LogVol02
|
Check the partition for errors by typing the following command
as root:
/sbin/e2fsck -y /dev/mapper/VolGroup00-LogVol02
|
Then mount the partition again as ext2 file system by
typing:
mount -t ext2 /dev/mapper/VolGroup00-LogVol02 /mount/point
|
In the above command, replace /mount/point with the mount point of the
partition.
Next, remove the .journal file at the
root level of the partition by changing to the directory where it
is mounted and typing:
You now have an ext2 partition.
If you want to permanently change the partition to ext2,
remember to update the /etc/fstab
file.
