[ovirt-users] hosted-engine migration problems on 3.6, 3.6.1, 3.6.2

I am running oVirt 3.6.2 (original install was 3.6) hosted-engine on a couple of Centos 7.2 servers with SAS attached storage using the new FC support to connect to the LUNs. Neither the hosted-engine storage nor the hosted-engine VM show up in the GUI. I know there have been a lot of bugs that have been fixed for this but I still can't import anything. This may be the basis of my problem. The problem is that I can't reliably get the hosted-engine to migrate to the other head. If all VMs and HE are running on node1 and I try to put it in maintenance the VMs will migrate but the HE will not and node1 will show 1 VM remaining on the node (even though the HE VM doesn't show up in the VM list) and will not go into maintenance. I try setting 'hosted-engine --set-maintenance --mode=local' but that doesn't always help. The output of 'hosted-engine --vm-status' eventually changes to show the local node in maintenance with score 0 but often it doesn't move. In /var/log/ovirt-hosted-engine-ha/agent.log I see MainThread::INFO::2016-01-28 03:15:42,951::config::205::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config::(refresh_local_conf_file) Trying to get a fresher copy of vm configuration from the OVF_STORE MainThread::WARNING::2016-01-28 03:15:43,296::ovf_store::105::ovirt_hosted_engine_ha.lib.ovf.ovf_store.OVFStore::(scan) Unable to find OVF_STORE MainThread::ERROR::2016-01-28 03:15:43,297::config::234::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config::(refresh_local_conf_file) Unable to get vm.conf from OVF_STORE, falling back to initial vm.conf MainThread::WARNING::2016-01-28 03:15:43,316::hosted_engine::767::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(_stop_domain_monitor_if_possible) The VM is running locally or we have no data, keeping the domain monitor. I've restarted servers and/or processes but I'm not getting anywhere. I appreciate any help.
