<p class="MsoNormal"><span style="color:black;mso-fareast-language:EN-US">Hi all,</span><span style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black;mso-fareast-language:EN-US"> </span><span style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black;mso-fareast-language:EN-US">The problem what I noticed is, in update stats we send thick and thin volume support as true. This issue can be reproduced.
</span><span style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black;mso-fareast-language:EN-US"> </span><span style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black;mso-fareast-language:EN-US">So the over provision and thick and thin parameters are reason, scheduler is not blocking for thick volume based on the capacity if it is thick, it Is passing to the driver which forces
driver to handle a particular use case!!</span><span style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black;mso-fareast-language:EN-US"> </span><span style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black;mso-fareast-language:EN-US">I believe this has to handle at the above layer, however it will not know what kind of volume is created using volume types, I think this also has to be considered in scheduler!</span><span style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black;mso-fareast-language:EN-US"> </span><span style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black;mso-fareast-language:EN-US"> </span><span style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black;mso-fareast-language:EN-US">Any one has a better approach? For this or is it better to write own filters to avoid writing in driver?</span><span style="color:black"><o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.5pt;color:#1F497D">Generally, Cinder scheduler will consume the free_capacity_gb after chose the host for a volume creation, could see the consume_from_volume function in host_manager.py.</span><span style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.5pt;color:#1F497D">That keep the pool capacity gb updated correctly when multi users are creating volume.</span><span style="color:black"><o:p></o:p></span></p>
