Env: ubuntu (3 controllers + 3 computes)
Steps: 1. ssh to one of the slave nodes 2. run curl to vip management ip
while :; do curl -s -w "%{http_code} %{time_total}" -i -X POST -H "Content-Type: application/json" -d '{"auth":{ "identity":{"methods":["password"],"password" :{"user":{"name":"admin","domain":{"id": "default" },"password": "admin"}}}}}' http://10.109.2.2:5000/v3/auth/tokens -o /dev/null; echo; sleep 1; done
sample result: 201 0.108 201 0.110 201 0.093 201 0.102 201 0.103
3. shutdown one of controllers (shutdown -P now)
sample result from curl: 201 1.080 201 0.391 201 0.102 201 0.110 201 0.303 201 0.123 201 0.107 502 0.689 201 0.133 201 0.158 503 3.005 201 0.101 201 0.093 503 40.004 201 0.205 201 0.127 201 3.188 201 3.135 201 0.304 201 0.110 201 3.186 201 0.122 201 3.098 201 0.105 201 0.102 201 0.177 201 0.094 201 3.108 201 3.101 201 3.124 201 3.105 201 3.128 201 0.148 201 0.214 201 0.086 201 0.101 201 0.090 201 0.157 201 0.092 201 3.118 201 0.095 201 3.112 201 3.141 201 3.173
Expected result: No changes in delays if one of controllers shutted down
Actual result: Delay changed from 0.1s to 3s (in 30%)
