[4.0] Fix neutron-ha-tool restart on configuration changes#2120
Merged
Conversation
When we toggle ssl/non-ssl in keystone, neutron-ha-tool gets a new config file but doesn't get restarted, so it just repeatedly crashes all the way until it causes a pacemaker failcount exceeded and then its dead. We should try better. (cherry picked from commit 65bdb6c)
When we restart via systemd, it can happen that the service already crashed and then 'service neutron-l3-ha-service status" will (correctly) report that the service isn't running. And then the restart is not being executed due to: INFO: Ignoring restart action for neutron-l3-ha-service service since not running on this node (d52-54-77-77-01-01) which will then later cause a pacemaker failcount. the pacemaker resource restart hopefully does not have this problem. (cherry picked from commit 3615437)
