Re: 3 etcd nodes don't work well in single zone

Amit Kumar Gupta

You should definitely not run etcd with 2 instances. You can read more about
recommended cluster sizes in the etcd docs:

I will look at the attached logs and get back to you, but wanted to make
sure to advise you to run either 1 or 3 nodes. With 2, you can wedge the
system, because it will need all nodes to be up to achieve quorum. If you
roll one of the two nodes, it will not be able to rejoin the cluster, and
the service will be stuck in an unavailable state.
