<p class="MsoNormal">Hi Irina<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Code review: <a href="https://review.openstack.org/#/c/618976/">
https://review.openstack.org/#/c/618976/</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m working of upstreaming this patch. Could you please help to address one doubt: why image is converted in the same location with image itself? This patch is to create a volume from image, right?
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I take a look of related code, the destination location would be the newly created volume and the source location is configured in cinder.conf, something like:<o:p></o:p></p>
<p class="MsoNormal">image_conversion_dir = /mnt/d100m/image_conversion_dir<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I did an experiment, in the latest master branch of cinder upstream repo:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l2 level1 lfo3"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>If image_conversion_dir has no space to store the downloading image, the exception ImageTooBig will be caught in the beginning of _create_from_image_cache_or_download().
<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l2 level1 lfo3"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>If has space to store the image, but dest volume size is smaller than image’s virtual size, an exception “ImageUnacceptable” will raised by check_virtual_size.
<o:p></o:p></p>
<p class="MsoNormal">So it seems no chance to go to the situation this patch aimed to solve.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Could you please help to give more background of this patch? Or if you think this patch is invalid now, please just tell me, I will mark this patch as abandoned.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks<o:p></o:p></p>
<p class="MsoNormal">Liang<o:p></o:p></p>
