<b><font face="ARIAL NARROW,HELVETICA">XFS for Linux Pre-Release 0.10 New Features</font></b></h2>

<p>
XFS for Linux Pre-release 0.10 differs from Pre-release
0.9 in the following ways:
</p>

<ul>
<li>
Pre-release 0.10 is based on the Linux 2.4.2 kernel.
</li>

<p>
<li>
Synchronous and direct I/O are now supported through 
the use of the O_SYNC and O_DIRECT file options.
</li> 

<p>
<li>
XFS 0.10 includes LVM 0.9.1 beta6 support.  To use it you need the
userland utilities from:

<p>
<pre><tt>ftp://ftp.sistina.com/pub/LVM/0.9.1_beta/lvm_0.9.1_beta6.tar.gz</tt></pre>
</p>

<p>
XFS 0.10 now supports MD RAID0, RAID1 and RAID5.
</p>
</li>
</p>

<p>
<li>
mkfs.xfs will now attempt to make a qualified guess of the logsize
depending on the size of the filesystem.
<p>
On MD-based volumes, mkfs.xfs will automatically extract the stripe
unit and stripe width.
</li>
</p>

<p>
<li>
Major performance improvements have been made for the NFS write path,
fixes to allow exporting XFS via the NFS V3 protocol have been made.
</li>
</p>

<p>
<li>
Rebooting with an xfs root filesystem is now much faster than
with XFS Pre-release 0.9.
</li>
</p>

<p>
<li>
The XFS code has been resynced with the IRIX code base.
</li>
</p>


</ul>
