Hello,
> Strangely I get "ssh: connect to host infra1_repo_container-20deb465 port 22: No route to host"
This could mean the hosts file doesn’t have an entry. It looks like the Ansible inventory has corresponding entries, so you’re probably fine there. From ‘infra1’, you can try ‘lxc-attach -n infra1_repo_container-20deb465’ to attach to the container directly, and run those same commands mentioned earlier. For the infra2 container, you’ll want to connect from infra2 with ‘lxc-attach’.
Can you confirm if this is Yoga or Master? Also, are you running w/ Rocky Linux 8.6 (as a previous thread indicates)? TBH I have not tested that, yet, and am not sure of the gotchas.

Here is the output from "setup-infrastructure.yml -vvv" https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpaste.opendev.org%2Fshow%2FbCGUOb177z2oC5P3nR5Z%2F&data=05%7C01%7Cjames.denton%40rackspace.com%7Cf947b56a0f9249d40cec08da80bfca26%7C570057f473ef41c8bcbb08db2fc15c2b%7C0%7C0%7C637963858891500677%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=DV2%2Bji7aeHe7HhAwGFmT8tkCWh2SS%2BKeHpAm1JVMIhs%3D&reserved=0

Strangely I get "ssh: connect to host infra1_repo_container-20deb465 port 22: No route to host"

A similar error for this too "ssh: connect to host infra2_repo_container-6cd61edd port 22: Network is unreachable"

Here is the verbose output for the glusterfs error: https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpaste.openstack.org%2Fshow%2Fbw0qIhUzuZ1de0qjKzfK%2F&data=05%7C01%7Cjames.denton%40rackspace.com%7Cf947b56a0f9249d40cec08da80bfca26%7C570057f473ef41c8bcbb08db2fc15c2b%7C0%7C0%7C637963858891500677%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=j2S5KZZnTHH9vD0oKEZfLxaNmjGxlEyCKbzoxxvXm5M%3D&reserved=0

I used the command: openstack-ansible lxc-containers-destroy.yml
I answered affirmatively to the two questions asked about the removal of the containers and the container data.
Thank you once again!

FYI: LXC containers will automatically be assigned IPs from the ‘container’ network outside of the ‘used_ips’ range(s). The infra host will communicate with the containers via this br-mgmt interface.

You can verify this by issuing a ‘curl -vhttps://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2F192.168.3.9%3A8181%2F%25E2%2580%2599&data=05%7C01%7Cjames.denton%40rackspace.com%7Cf947b56a0f9249d40cec08da80bfca26%7C570057f473ef41c8bcbb08db2fc15c2b%7C0%7C0%7C637963858891500677%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=%2BK4QPjACSUzlGKvXGmijRhDooI5CjuEvyIo%2BPJIM3is%3D&reserved=0. You might check the haproxy service status and/or keepalived status to ensure they are operating properly. If the IP cannot be bound to the correct interface, keepalive may not start.
