When I run ceph-install.yml  I some how get the following error:
TASK [ceph-facts : set_fact monitor_name ansible_hostname] *********************************************************************************************************************************************************************************************************************
fatal: [storko1]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'ansible.vars.hostvars.HostVarsVars object' has no attribute 'ansible_hostname'\n\nThe error appears to be in '/etc/ansible/roles/ceph-ansible/roles/ceph-facts/tas
ks/facts.yml': line 27, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: set_fact monitor_name ansible_hostname\n  ^ here\n"}
