<p class="MsoNormal">Hi all:<o:p></o:p></p>
<p class="MsoNormal"> I encouted a problem when I tried to create vm from a big-size image(4G) on a AIO node, and get error messages like:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">‘’’VolumeNotCreated: Volume 4c186b68-542e-453c-ab77-0e5272337289 did not finish being created

<p class="MsoNormal" style="margin-left:.5in">Tuning parameters “<span style="font-size:10.5pt;font-family:"Arial",sans-serif;color:#4B4B4B;background:white">block_device_allocate_retries”, “block_device_allocate_retries_interval” in nova.conf of compute node
can resolve the problem.<o:p></o:p></span></p>
<p class="MsoNormal"> But after checking current nova.conf in nova-compute pods, found nova.conf have already been set like that<o:p></o:p></p>
<p class="MsoNormal"> [DEFAULT]<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:.5in">‘’’<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in">Seem retries(2400)*interval(3)=7800 sec didn’t take effect on my env.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">Did anyone encounter that problem before ? Glad for any suggestion.<o:p></o:p></p>
