played with --availability-zone, so after specifying:<br>

I can create volumes just fine without --availability-zone, however they are always created on "primary" cinder node that runs cinder-api, cinder-scheduler and cinder-volume and not on secondary that runs cinder-api and cinder-volume. <br>
<br>
I have added to /etc/cinder/cinder.conf:<br>
<br>
iscsi_ip_prefix= 1.1.1.2<br>
<br>
and <br>
<br>
iscsi_ip_prefix= 1.1.1.3<br>
<br>
<br>
on both hosts but I get nothing. creation with availability zone specified fails every time. <br>
<br>
from /var/log/cinder/scheduler.log on primary node I get:<br>

does that mean I have to run Qpid on secondary as well?<br>
