<p class="MsoNormal">Currently using openstack Xena and
Ceph backend (Pacific 16.2.7)</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">It seems there is a bug (since
Wallaby?) where the efficient use of a CEPH Pacific
RBD backend (i.e with copy-on-write-cloning) is not
working .</p>
<p class="MsoNormal">Show_image_direct_url needs to be
False to create volumes (or ephemeral volumes for
nova)</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">This can of course be tremendously
slow (Nova , ephemeral root disk) without
copy-on-write cloning feature of Ceph.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">As Ceph RBD is THE most favourite
backend for block storage in openstack I am wondering
how others are coping (or workarounds found ?)</p>
<p class="MsoNormal">Which combinations of Openstack and
Ceph are known to work well with
copy-on-write-cloning?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">How is the noted <i>GRAVE Security
RISK of enabling </i>Show_image_direct_url
mitigated ? (i.e I think , for CEPH RBD, it needs
to be True to get cloning to work efficiently)</p>
