Hello, I have 2 cinder-volume servers, each one with 2 storage backends. Each of those cinder-volume servers are on different availability zones (tdc-a and tdc-b), and there are 8 nova-compute servers (4 on tdc-a and 4 on tdc-b) When I launch a new instance using the zone tdc-a Nova choose the right zone to place the instance, but the volume some times is placed on different zone. I tried with many nova/cinder configurations changing scheduler_driver, scheduler_default_filters but always with the same result. I'm not sure about how to debug it. I added to /usr/lib/python2.7/dist-packages/cinder/openstack/common/scheduler/filters/availability_zone_filter.py one line to print at the log file what AZ is receiving and looks like Nova is sending a random zone no matter what zone I have chosen. I appreciate any help! Thanks!!
