<div dir="ltr">We're currently running two systems (in the middle of a migration). In both, we just have the basic brick level replication, using 2 way replication in one case, and 4 way in the other. We're running a relatively small image archive; about 1TB. <div>

<br>How can I have multiple glance nodes in a way that, when I
create an image from the controler, it would be coppied to all of the
glance nodes?<br>Now, when I define multiple glance endpoints in the controler (keystone), the images would only go to the first glance node.<br><br>I also want to avoid putting the name of all glance nodes in the nova nodes.<br>
