ha not working when deployed in phycal nodes

[Samantha Jian-Pielak]

When deploying quantum-gateway with ha-legacy-mode enabled, it only works when deployed to the lxc containers. The corosync and pacemaker won't start if deployed to physical nodes.

Please can we get the full juju logs from /var/log/juju from this deployment, the output of juju status and all of the configuration options being used for quantum-gateway and hacluster in this deployment.

Hi James,

Thanks for looking into this. Here is the steps to reproduce the issue:

1. Deploy service (ex, mysql) to 3 of physical nodes by using Juju. -> OK

2. Deploy trusty/hacluster-18 -> OK

3. Hook up relation between mysql – hacluster -> Hookup failed.

4. Use “juju resolved –retry” command to fix issue -> no help. Still shows red line.

5. Login to one of physical node to run a check.

a. Verify the corosync & pacemaker status -> both of services not start

b. Verify corosync.conf -> mysql HA setting hasn’t been written to this file.

c. Run “sudo crm_mon” -> connection refused. Node cluster failed.

*I can also reproduce the issue by following the steps:

Mine step was:

1. bootstrap
2. juju deploy -n 3 -constrains tags=physical keystone
3. juju deploy hacluster hacluster-keystone
4. juju add-relation hacluster-keystone keystone

juju stat keystone gives:

even if I deploy services to the container, the hooks will fail as well.

Attach logs for analysis

ha-legacy-mode was always a bit of a stop gap until Neutron grew support for HA router support, so I'm going to mark this as Won't Fix - we should also drop support from the charm at a suitable point in time.
