Description of Changes:

Before upgrading, users are encouraged to read the OCFS2 1.4 User's
Guide to learn about the new features, compatibility issues and also
about the new file system defaults.

Please note that this release only works on Enterprise Linux Release 5
U2 or later. The earliest supported kernel version is 2.6.18-92.el5. It
will not work with the older kernels. Needless to add, users looking to
use OCFS2 1.4 will have to upgrade to Enterprise Linux Release 5 U2.

NEW FEATURES

The list of new features added since the OCFS2 1.2 release is as follows:

  * Ordered Journaling Mode
  * File Attribute Support
  * Performance Enhancements
        - Directory Readahead
        - File Lookup
        - File Remove and Rename
  * Splice IO
  * Access Time Updates
  * Flexible Allocations
        - Sparse File Support
        - Unwritten Extents
        - Punching Holes
  * Shared Writeable mmap(2)
  * Inline Data ##
  * Online File System Resize
  * Clustered flock(2)

For the full description of these features, please refer to the
OCFS2 1.4 User's Guide.

FILESYSTEM COMPATIBILITY

OCFS2 1.4 can mount volumes created and used by OCFS2 1.2 release,
as-is.

However, some new features will not be enabled by default. These include
sparse files, unwritten extents and inline data. These features will
need to be explicitly enabled using tunefs.ocfs2. Once enabled, the same
volume can still be mounted by the older file system but only after the
said feature is disabled using tunefs.ocfs2. Refer to the User's Guide
and the man pages for more.

TOOLS COMPATIBILITY

The latest release of the tools always supports all existing versions of
the file system. This includes OCFS2 1.2, OCFS2 1.4 and the version of
the file system in the mainline Linux kernel.

Having said that, we are not recommending OCFS2 1.2 file system users
to install the 1.4 tools. This is because the defaults in the new tools
have been selected for the 1.4 file system release.

NEW FILESYSTEM DEFAULTS

Sparse files and Unwritten extents are enabled by default by the new
mkfs.ocfs2. Users wishing to retain full compatibility with the older
file system release should specify "--fs-feature-level=max-compat"
during format.

The file system now defaults to the ordered data journaling mode. Users
wishing to use the writeback data journaling mode will need to mount
with the "data=writeback" mount option. Refer to the User's Guide to
learn about the differences between the two modes.
