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:
In the above command, replace hdb with the
drive letter and X with the
partition number. For the remainder of this section, the sample commands will
use hdb1 for these values.
Next, change the file system type to ext2 by typing:
/sbin/tune2fs -O ^has_journal /dev/hdb1 |
Check the partition for errors by typing:
/sbin/e2fsck -y /dev/hdb1 |
Then mount the partition again as ext2 file system by typing:
mount -t ext2 /dev/hdb1 /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.
