I tried upgrade my production Environment using fuel 6.1 to 7.0 but i have a error:

"Failed to call refresh: ceilometer-dbsync --config-file=/etc/ceilometer/ceilometer.conf returned 1 instead of one of [0]"

I followed the this procedure https://docs.mirantis.com/openstack/f... the error happens at step 4:

octane upgrade-node --isolated $SEED_ID <id>

I pasted the full log output in http://paste.openstack.org/show/483951/

My original environment is online, but one controller was removed. How can I resolved this problem or rollback the controller ?
