</div></div>Hi,<br>
<br>
When properly set with the right configuration and the right system and<br>
OpenStack packages, Cinder, OS-Brick, and Nova no longer have race<br>
conditions with iSCSI operations anymore (single or multipathed), not<br>
even with drivers that do "shared target".<br>
<br>
So I would assume that Glance won't have any issues either as long as<br>
it's properly making the Cinder and OS-Brick calls.<br>
<br>
Cheers,<br>
Gorka.<br>
