<div dir="ltr">The flow for all images for this process is to download from Glance to a temporary file, and then write to volume. This is not necessary for raw images, but that optimization has not been done. I did leave a comment about that in the code though 2.5 years ago, but never implemented it - you can give it a go if you'd like :-)<div><br></div><div>Are you using two different Ceph clusters, one for images and one for volumes?

<p class="MsoNormal">When creating a volume from an image(Using Horizon), why does the Cinder server need to do what appears to be a conversion of the image before it can create the volume?<u></u><u></u></p>
<p class="MsoNormal">All of my images in Glance are uploaded in RAW format, images and volumes are stored in Ceph.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">The reason I know the images are being processed on my glance server is because it runs out of disk space when trying to make volumes from large images and the process fails. I can see the temporary file in /var/lib/cinder/conversion<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Is it not possible to have glance simply copy the image form the images store into the volumes store? I am going to regularly be creating new Windows Server instances, so it would take quite some time for a 20gb image to be processed by
Cinder before it can be uploaded into Ceph.<u></u><u></u></p>
