<p class="MsoNormal">Hi nova devs,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Just wanted to ask regarding request zero root disk for boot-from-volume instances patches [2] [3].<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When user boot instance using bootable volume and flavor having non-zero disk_gb<o:p></o:p></p>
<p class="MsoNormal">then in that case it considers flavor disk_gb which is incorrect the calculation of host<o:p></o:p></p>
<p class="MsoNormal">disk space.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b><u>Request</u>:<o:p></o:p></b></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What are reconditions from the community to resolve the LP bug Reference: [1]?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Through multiple discussion on the patches there are two options to address this issue:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b><u>Option 1</u>:<o:p></o:p></b></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Merging of patches Reference: [2] and [3] <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b><u>Option 2</u>:<o:p></o:p></b></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Operators will need to create new flavor with root_disk=0 for BFV<o:p></o:p></p>
<p class="MsoNormal">and ask users to use this new flavor if they want to boot the instance from volume.<o:p></o:p></p>
<p class="MsoNormal">(Release note may need to be updated in this case)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Could you please give opinion above two options.<o:p></o:p></p>
