In reply to Thanh Tung.

Please change permission of /etc/ceph directory and their internal file.

#chown cephadm /etc/ceph/*
#chogro cephadm /etc/ceph/*

In reply to Thanh Tung. Ran into the same problem. Was running on openstack centos 7 and found the security group in which my servers were part of did not have the correct ports open(as suggested in the firewall section in the article)
