This is a very common error and it happens when some parameters are missing or wrong in the /etc/ceph/ceph.conf file. Looking at your ceph.conf file, it seems your error is due to following three parameters:

  • mon_initial_members =.....
  • mon_host =.....
  • public_network=.....

For network configurations and particularly public network configuration check following three options:

Also make sure that the hostname on the server is the same in the ceph.conf file.

Apart from it, it can also be related to firewall like this.
