The Ceph Deploy Mon Create Initial Fails

The error happens when some parameters are missing from the /etc/ceph/ceph.conf file.

[global]
fsid = 5xcxxc76-a6x5-23x9e-ecdd-e7c9x3f4d
mon_initial_members = ceph1,ceph2
mon_host = 19x.1xx.xx.xx,1xx.16x.xx.xx
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
filestore_xattr_use_omap = true
public_network = 1xx.1xx.x1.0/24
