[Gluster-users] (3.1.6-1) How should I add extra peers to existing file systems ?

[Mohit Anchlia]

What's in your logs?

Did you have  foo-3-private before in your gluster cluster ever or
adding this host for the first time?

Try gluster peer detach and then remove any left over configuration in
/etc/glusterd config directory. After that try again and see if that
works.
