Bug 1316183

Created attachment 1134558 [details]
/var/log/neutron/server.log from Controller

Description of problem:

Repos setup as follows :-

Install the yum-plugin-priorities package:
yum -y install yum-plugin-priorities

For CentOS 7 and RHEL 7, install the required .repo files:
cd /etc/yum.repos.d/
curl -O http://trunk.rdoproject.org/centos7/delorean-deps.repo
curl -O http://trunk.rdoproject.org/centos7/current-passed-ci/delorean.repo

Upon completion of packstack install

[root@ip-192-169-142-127 ~]# nova-manage version
13.0.0-0.20160304162843.c5a45a2.el7.centos
 

System Controller && Compute is configured and successfully running DVR  
Configuration was done exactly as it is supposed to be done on Liberty

Update neutron.conf:-

l3_ha = True
min_l3_agents_per_router = 2
l3_ha_net_cidr = 169.254.192.0/18

# openstack-service restart neutron - success

Two L3 agents are running on the system ML2&OVS&VXLAN setup via packstack

Not enough l3 agents available to ensure HA. Minimum required 2, available 1.

python-neutron-8.0.0.0b4-0.20160304174813.0ae20a3.el7.centos.noarch


How reproducible:


Steps to Reproduce:
1. Build Controller/Network && Compute nodes cluster
2. Convert to DVR (OK)
3. Enable l3_ha in neutron.conf
4. Restart neutron services

Actual results:

neutron router-create --distributed True --ha True   --tenant-id c10e12e26c67477ebe1c1127b2e810aa Router01
Not enough l3 agents available to ensure HA. Minimum required 2, available 1


Expected results:

Distributed and L3_HA neutron router gets created due to plesence two L3
routers on cluster ( DVR is running with no problems )
