<p class="MsoNormal">Hello All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m proposing a feature of LVM driver to support LVM on a shared LU.<span style="mso-fareast-language:JA"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:JA">The proposed LVM volume driver provides these
</span>benefits<span style="mso-fareast-language:JA">.</span><br>
<span style="mso-fareast-language:JA"> </span>- <span style="mso-fareast-language:JA">
R</span>educe hardware based storage workload by offloading the workload to software based volume operation.<br>
<span style="mso-fareast-language:JA"> </span>- Provide quicker volume creation and snapshot creation without storage workloads.<br>
<span style="mso-fareast-language:JA"> </span>- Enable cinder to any kinds of shared storage volumes without specific cinder storage<span style="mso-fareast-language:JA">
</span>driver.<span style="mso-fareast-language:JA"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:JA"> </span>-<span style="mso-fareast-language:JA"> Better I/O performance using direct volume access via Fibre channel.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:JA"><o:p> </o:p></span></p>
<p class="MsoNormal">In the attachment pdf, following contents are explained.<o:p></o:p></p>
<p class="MsoNormal"> 1. Detail of Proposed LVM volume driver<o:p></o:p></p>
<p class="MsoNormal"> 1-1. Big Picture<o:p></o:p></p>
<p class="MsoNormal"> 1-2. Administrator preparation<o:p></o:p></p>
<p class="MsoNormal"> 1-3. Work flow of volume creation and attachment<o:p></o:p></p>
<p class="MsoNormal"> 2. Target of Proposed LVM volume driver<o:p></o:p></p>
<p class="MsoNormal"> 3. Comparison of Proposed LVM volume driver<o:p></o:p></p>
