What's in your logs?
I can obtain logs needed. could you tell me the instruction to take the logs?
Did you have foo-3-private before in your gluster cluster ever or
adding this host for the first time?
It was first time.
All foo-X-private has no entries in /etc/glusterd/peers/ and
/etc/glusterd/vols/.
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.

Hi,
following instructions work fine with 3.1.5-1 but with 3.1.6-1.
1. make a new file system without peers. [OK]
foo-1-private# gluster volume create foo foo-1-private:/mnt/brick

How should I add extra peers to existing file systems ?
Best,
