Description of problem:
=======================
Choose directory instead of disk for OSDs in osds file. Installation fails 'start and add that the OSD service to the init sequence' task .


Version-Release number of selected component (if applicable):
=============================================================
ceph-ansible-1.0.5-5.el7scon.noarch


How reproducible:
=================
always


Steps to Reproduce:
==================
1. perform pre flight checkin on all nodes
2.choose directory instead of disk for OSDs in osds file.
3. install ceph by executing below command
ansible-playbook site.yml -vv -i  /etc/ansible/hosts  --extra-vars '{"ceph_stable": true, "ceph_origin": "distro", "ceph_stable_rh_storage": true, "monitor_interface": "eno1",  "journal_size": 100, "public_network": "10.8.128.0/21"}' -u root

Actual results:
===============

TASK: [ceph-osd | start and add that the OSD service to the init sequence] **** 
fatal: [magna063] => error while evaluating conditional: ansible_service_mgr != "systemd"
fatal: [magna067] => error while evaluating conditional: ansible_service_mgr != "systemd"
fatal: [magna066] => error while evaluating conditional: ansible_service_mgr != "systemd"

FATAL: all hosts have already failed -- aborting

PLAY RECAP ******************************************************************** 
           to retry, use: --limit @/root/site.retry

magna051                   : ok=68   changed=11   unreachable=0    failed=0   
magna063                   : ok=96   changed=10   unreachable=1    failed=0   
magna066                   : ok=96   changed=10   unreachable=1    failed=0   
magna067                   : ok=96   changed=10   unreachable=1    failed=0   


---> all osds are down

Expected results:
=================
1. It should start osds.
2. Ansible should not show unreachable in node summry when all nodes where reachable
