HA cluster restore doesn't work

[felipegouveiae]

Summary

I setup a HA 3 node cluster. I ran daily backup on the main node. After restoring the VM microk8s hangs and running inspect is says that:

cp: cannot stat '/var/snap/microk8s/6641/var/kubernetes/backend/localnode.yaml': No such file or directory

The IP address changed so I also tried to update the /var/snap/microk8s/6641/var/kubernetes/backend/cluster.yaml and /var/snap/microk8s/6641/var/kubernetes/backend/info.yaml with the new IP and doesn't work as well.

I noticed that the localnode.yaml looks like info.yaml and copied so local node.yaml would be available. no dice.

What Should Happen Instead?

The server should be available in a single node mode.

Reproduction Steps

1. Setup a new HA 3 node cluster
2. Backup the main node (snapshot the VM)
3. Restore the snapshot into a new VM;
4. Login on the VM and try to start microk8s
