I have been testing masakari's host evacuation functionality and have observed that it does not always evacuate the VMs on a host when that host is powered off.
I have a 10 node bionic-stein openstack running (1 neutron-gateway and 9 nova-computes).
I created 10 instances and also created the following failover segment:
https://pastebin.canonical.com/p/4JV7p4tf2V/
I proceeded to SSH into the hosts with instances on them and run sudo poweroff to shut them down.
I would do this one by one until I got into a situation where the host was powered off, but the instance was not evacuated. Once the powered off hosts come back up, I can see with virsh list --all that the instance is still there but not running. In the latest test, this happened to the 3rd node I powered off.
I am using the following bundle:
https://pastebin.canonical.com/p/M2zMWMHjf8/
My bundle is using the latest masakari charm from cs:~openstack-charmers-next/masakari to use the
check-expired-interval: 60
notification-expiration: 60
config options. I had a similar experience though with the latest charms from cs:~openstack-charmers/masakari. |
