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
To revert a partition, you must first unmount the partition by logging
in as root and typing,
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
You now have an ext2 partition.
If you want to permanently change the partition to ext2, remember to
update the /etc/fstab file.
