After restart from a 3.8.15 server:
root at 1-gls-dus10-ci-efood-real-de:/home/ubuntu# gluster peer status
Number of Peers: 4

After restart from the 3.10.10 server:

root at 2-gls-dus21-ci-efood-real-de:/home/ubuntu# gluster peer status

I have deleted the "tier-enabled=0" line and without restart "gluster peer
status" is the same as above. I also tried to re-peer that upgraded server but
got:

root at 1-gls-dus10-ci-efood-real-de:/home/ubuntu# gluster peer detach
2-gls-dus21-ci-efood-real-de.openstacklocal
peer detach: failed: Brick(s) with the peer
2-gls-dus21-ci-efood-real-de.openstacklocal exist in cluster
root at 1-gls-dus10-ci-efood-real-de:/home/ubuntu# gluster peer probe
2-gls-dus21-ci-efood-real-de.openstacklocal
peer probe: success. Host 2-gls-dus21-ci-efood-real-de.openstacklocal port
24007 already in peer list
