[SOLVED] HA failover not working

hello all,
first of all thank you for providing such a good system.
i’ve a question about HA. Right now, in our staging system, I’ve deployed my HA Cluster in the following configuration:
1x rancher/rancher server
2x all roles server
2x worker server.

for testing purpose, I’ve shutted down 1 of the 2 “all roles server” (kube3) and the cluster stopped working with the following error message:

This cluster is currently Unavailable; areas that interact directly with it will not be available until the API is ready.

Failed to communicate with API server: Get net/http: request canceled (Client.Timeout exceeded while awaiting headers)

what’s wrong in my configuration?
thank you very much
best regards

I think an odd number of servers is required for etcd and controlplane roles (specifically 1, 3, or 5). Try adding another “All roles” server to see if it works then.

Hi Pib,
you were right. Adding a 3rd server with all roles worked correctly, once a server is unavailable.
thank you very much.
best regards
