| #### Fallback to proxy mode with discovery service | |||
| If you bootstrap a etcd cluster using [discovery service][discovery-service] with more than the expected number of etcd members, the extra etcd processes will fall back to being `readwrite` proxies by default. They will forward the requests to the cluster as described above. For example, if you create a discovery url with `size=5`, and start ten etcd processes using that same discovery url, the result will be a cluster with five etcd members and five proxies. Note that this behaviour can be disabled with the `proxy-fallback` flag. | |||

| ### Promote a proxy to a member of etcd cluster | |||
|
|
|||
| A Proxy is not part of the core etcd cluster. A proxy will not promote itself to an etcd member automtically in any case. | |||
There was a problem hiding this comment.
Can we use the word consensus in here somewhere? "subset of the cluster participating in consensus" or similar.

@robszumski All fixed. Can you take another look. @robszumski @yichengq For the systemd drop-in, I have no strong opinion. I feel people should be able to figure it out though. If @robszumski really want that I will add it again. If @yichengq strongly disagrees on that, I think you guys can figure it out. |
