ceph Jewel ceph-deploy mon criar com falha

Question

Estou tentando fazer um cluster ceph com 3 nós no Ubuntu 16.04.

Eu segui esta e este guia mas estou tropeçando na parte ceph-deploy mon create-initial .

Eu também tentei ceph-deploy --overwrite-conf mon create ceph-node1 ceph-node2 ceph-node3 , mas o resultado foi o mesmo:

A mensagem começa a repetir novamente para os outros 2 nós e depois pára.

Alguém pode ajudar?
