<p class="MsoNormal">During the TWG concall this morning, we walked through the comments several reviewers had made to our 2012 requirements document. Several of us spent the rest of the day editing the text and resolving the remaining comments (thanks, Alex,
Andreas, Cory, Josh and Nathan!)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It’s now your opportunity to review the document (<a href="http://goo.gl/63u9Q">http://goo.gl/63u9Q</a>) to help us select the requirements we will recommend to the OpenSFS Board for development in 2013.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As we did last year, we need to create a short list of 4-5 items we think are most important to the Lustre community. The OpenSFS Board must agree with our recommendation before we can pursue proposals to meet these requirements.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now that we have finished gathering requirements, the first step is for community members to send their top 10 requirements from the list below in priority order to
<a href="mailto:discuss@lists.opensfs.org">discuss@lists.opensfs.org</a>. We will discuss how to resolve our lists and make the recommendation to the board at the TWG face to face meeting (Weds 4/25 after LUG in Austin). <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please send questions or comments to the <a href="mailto:discuss@lists.opensfs.org">
discuss@lists.opensfs.org</a> reflector. <o:p></o:p></p>

<p class="MsoNormal">The following table summarizes the 31 gathered requirements described in our document (<a href="http://goo.gl/63u9Q">http://goo.gl/63u9Q</a>). Category definitions are only meant to help organize requirements for discussion. There is
no significance to the order in which the requirements are listed. <o:p></o:p></p>
